Define a new component class.
If a slot should be a property-, rather than a standard-slot, you must supply
the :PROPERTY slot initarg. The :PROPERTY initarg must name a property class.
Property-slots allow constraints to be enforced on their values using the
:CONSTRAINT initarg. Constraints must have the following form:
CONSTRAINT ::= MULTIPLICITY | RELATION
MULTIPLICITY ::= :REQUIRED | :OPTIONAL | :MULTIPLE
RELATION ::= (and SLOT-NAME) | (not SLOT-NAME)
SLOT-NAME — The name of another property-slot on the component.
If the multiplicity is :REQUIRED, the slot may not be unbound. If it is :MULTIPLE, the slot may contain a list of property instances. If it is a relational and, the other slot must be bound as well if this slot is bound. If it is a relational not, the other slot must not be bound if this slot is bound.

This parameter describes a time zone identifier for the property’s value.
Must be a TEXT.
From RFC5545:
This parameter MUST be specified on the DTSTART,
DTEND, DUE, EXDATE, and RDATE properties when either a
DATE-TIME or TIME value type is specified and when the value is
neither a UTC or a floating time. Refer to the DATE-TIME or
TIME value type definition for a description of UTC and floating
time formats. This property parameter specifies a text value
that uniquely identifies the VTIMEZONE calendar component to be
used when evaluating the time portion of the property. The value
of the TZID property parameter will be equal to the value of the
TZID property for the matching time zone definition. An
individual VTIMEZONE calendar component MUST be specified for
each unique TZID parameter value specified in the iCalendar
object.
The parameter MUST be specified on properties with a DATE-TIME
value if the DATE-TIME is not either a UTC or a floating time.
Failure to include and follow VTIMEZONE definitions in iCalendar
objects may lead to inconsistent understanding of the local time
at any given location.
The presence of the SOLIDUS character as a prefix, indicates that
this TZID represents a unique ID in a globally defined time zone
registry (when such registry is defined).
Note: This document does not define a naming convention for
time zone identifiers. Implementers may want to use the naming
conventions defined in existing time zone specifications such
as the public-domain TZ database [TZDB]. The specification of
globally unique time zone identifiers is not addressed by this
document and is left for future study.
The following are examples of this property parameter:
DTSTART;TZID=America/New_York:19980119T020000
DTEND;TZID=America/New_York:19980119T030000
The TZID property parameter MUST NOT be applied to DATE
properties and DATE-TIME or TIME properties whose time values are
specified in UTC.
The use of local time in a DATE-TIME or TIME value without the
TZID property parameter is to be interpreted as floating time,
regardless of the existence of VTIMEZONE calendar components in
the iCalendar object.

From RFC5545:
This parameter can be specified on properties that
specify an alarm trigger with a "DURATION" value type. The
parameter specifies whether the alarm will trigger relative to the
start or end of the calendar component. The parameter value START
will set the alarm to trigger off the start of the calendar
component; the parameter value END will set the alarm to trigger
off the end of the calendar component. If the parameter is not

Must be a string or one of :BINARY :BOOLEAN :CAL-ADDRESS :DATE :DATE-TIME :DURATION :FLOAT :INTEGER :PERIOD :RECUR :TEXT :TIME :URI :UTC-OFFSET.
From RFC5545:
This parameter specifies the value type and format of
the property value. The property values MUST be of a single value
type. For example, a RDATE property cannot have a combination
of DATE-TIME and TIME value types.
If the property’s value is the default value type, then this
parameter need not be specified. However, if the property’s
default value type is overridden by some other allowable value
type, then this parameter MUST be specified.
Applications MUST preserve the value data for x-name and iana-
token values that they don’t recognize without attempting to
interpret or parse the value data.

Description of a date and time on the calendar.
From RFC5545:
If the property permits, multiple DATE-TIME values
are specified as a COMMA-separated list of values. No additional
content value encoding (i.e., BACKSLASH character encoding, see
Section 3.3.11) is defined for this value type.
The DATE-TIME value type is used to identify values that contain
a precise calendar date and time of day. The format is based on
the [ISO.8601.2004] complete representation, basic format for a
calendar date and time of day. The text format is a concatenation
of the date, followed by the LATIN CAPITAL LETTER T character,
the time designator, followed by the time format.
The DATE-TIME value type expresses time values in three forms:
The form of date and time with UTC offset MUST NOT be used. For
example, the following is not valid for a DATE-TIME value:
19980119T230000-0800 ;Invalid time format
FORM #1: DATE WITH LOCAL TIME
The date with local time form is simply a DATE-TIME value that
does not contain the UTC designator nor does it reference a time
zone. For example, the following represents January 18, 1998, at
11 PM:
19980118T230000
DATE-TIME values of this type are said to be floating and are
not bound to any time zone in particular. They are used to
represent the same hour, minute, and second value regardless of
which time zone is currently being observed. For example, an
event can be defined that indicates that an individual will be
busy from 11:00 AM to 1:00 PM every day, no matter which time zone
the person is in. In these cases, a local time can be specified.
The recipient of an iCalendar object with a property value
consisting of a local time, without any relative time zone
information, SHOULD interpret the value as being fixed to whatever
time zone the ATTENDEE is in at any given moment. This means
that two Attendees, in different time zones, receiving the same
event definition as a floating time, may be participating in the
event at different actual times. Floating time SHOULD only be
used where that is the reasonable behavior.
In most cases, a fixed time is desired. To properly communicate a
fixed time in a property value, either UTC time or local time with
time zone reference MUST be specified.
The use of local time in a DATE-TIME value without the TZID
property parameter is to be interpreted as floating time,
regardless of the existence of VTIMEZONE calendar components in
the iCalendar object.
FORM #2: DATE WITH UTC TIME
The date with UTC time, or absolute time, is identified by a LATIN
CAPITAL LETTER Z suffix character, the UTC designator, appended to
the time value. For example, the following represents January 19,
1998, at 0700 UTC:
19980119T070000Z
The TZID property parameter MUST NOT be applied to DATE-TIME
properties whose time values are specified in UTC.
FORM #3: DATE WITH LOCAL TIME AND TIME ZONE REFERENCE
The date and local time with reference to time zone information is
identified by the use the TZID property parameter to reference
the appropriate time zone definition. TZID is discussed in
detail in Section 3.2.19. For example, the following represents
2:00 A.M. in New York on January 19, 1998:
TZID=America/New_York:19980119T020000
If, based on the definition of the referenced time zone, the local
time described occurs more than once (when changing from daylight
to standard time), the DATE-TIME value refers to the first
occurrence of the referenced time. Thus, TZID=America/
New_York:20071104T013000 indicates November 4, 2007 at 1:30 A.M.
EDT (UTC-04:00). If the local time described does not occur (when
changing from standard to daylight time), the DATE-TIME value is
interpreted using the UTC offset before the gap in local times.
Thus, TZID=America/New_York:20070311T023000 indicates March 11,
2007 at 3:30 A.M. EDT (UTC-04:00), one hour after 1:30 A.M. EST
(UTC-05:00).
A time value MUST only specify the second 60 when specifying a
positive leap second. For example:
19970630T235960Z
Implementations that do not support leap seconds SHOULD interpret
the second 60 as equivalent to the second 59.

Describes a period of time.
From RFC5545:
If the property permits, multiple period values are
specified by a COMMA-separated list of values. There are two
forms of a period of time. First, a period of time is identified
by its start and its end. This format is based on the
[ISO.8601.2004] complete representation, basic format for DATE-
TIME start of the period, followed by a SOLIDUS character
followed by the DATE-TIME of the end of the period. The start
of the period MUST be before the end of the period. Second, a
period of time can also be defined by a start and a positive
duration of time. The format is based on the [ISO.8601.2004]
complete representation, basic format for the DATE-TIME start of
the period, followed by a SOLIDUS character, followed by the
[ISO.8601.2004] basic format for DURATION of the period.
See MAKE-PERIOD
See PERIOD-START
See PERIOD-LIMIT
Describes the rules for a recurring component.
From RFC5545:
This value type is a structured value consisting of a
list of one or more recurrence grammar parts. Each rule part is
defined by a NAME=VALUE pair. The rule parts are separated from
each other by the SEMICOLON character. The rule parts are not
ordered in any particular sequence. Individual rule parts MUST
only be specified once. Compliant applications MUST accept rule
parts ordered in any sequence, but to ensure backward
compatibility with applications that pre-date this revision of
iCalendar the FREQ rule part MUST be the first rule part specified
in a RECUR value.
The FREQ rule part identifies the type of recurrence rule. This
rule part MUST be specified in the recurrence rule. Valid values
include SECONDLY, to specify repeating events based on an interval
of a second or more; MINUTELY, to specify repeating events based
on an interval of a minute or more; HOURLY, to specify repeating
events based on an interval of an hour or more; DAILY, to specify
repeating events based on an interval of a day or more; WEEKLY, to
specify repeating events based on an interval of a week or more;
MONTHLY, to specify repeating events based on an interval of a
month or more; and YEARLY, to specify repeating events based on an
interval of a year or more.
The INTERVAL rule part contains a positive integer representing at
which intervals the recurrence rule repeats. The default value is
1, meaning every second for a SECONDLY rule, every minute for a
MINUTELY rule, every hour for an HOURLY rule, every day for a
DAILY rule, every week for a WEEKLY rule, every month for a
MONTHLY rule, and every year for a YEARLY rule. For example,
within a DAILY rule, a value of 8 means every eight days.
The UNTIL rule part defines a DATE or DATE-TIME value that bounds
the recurrence rule in an inclusive manner. If the value
specified by UNTIL is synchronized with the specified recurrence,
this DATE or DATE-TIME becomes the last instance of the
recurrence. The value of the UNTIL rule part MUST have the same
value type as the DTSTART property. Furthermore, if the
DTSTART property is specified as a date with local time, then
the UNTIL rule part MUST also be specified as a date with local
time. If the DTSTART property is specified as a date with UTC
time or a date with local time and time zone reference, then the
UNTIL rule part MUST be specified as a date with UTC time. In the
case of the STANDARD and DAYLIGHT sub-components the UNTIL
rule part MUST always be specified as a date with UTC time. If
specified as a DATE-TIME value, then it MUST be specified in a UTC
time format. If not present, and the COUNT rule part is also not
present, the RRULE is considered to repeat forever.
The COUNT rule part defines the number of occurrences at which to
range-bound the recurrence. The DTSTART property value always
counts as the first occurrence.
The BYSECOND rule part specifies a COMMA-separated list of seconds
within a minute. Valid values are 0 to 60. The BYMINUTE rule
part specifies a COMMA-separated list of minutes within an hour.
Valid values are 0 to 59. The BYHOUR rule part specifies a COMMA-
separated list of hours of the day. Valid values are 0 to 23.
The BYSECOND, BYMINUTE and BYHOUR rule parts MUST NOT be specified
when the associated DTSTART property has a DATE value type.
These rule parts MUST be ignored in RECUR value that violate the
above requirement (e.g., generated by applications that pre-date
this revision of iCalendar).
The BYDAY rule part specifies a COMMA-separated list of days of
the week; SU indicates Sunday; MO indicates Monday; TU indicates
Tuesday; WE indicates Wednesday; TH indicates Thursday; FR
indicates Friday; and SA indicates Saturday.
Each BYDAY value can also be preceded by a positive (+n) or
negative (-n) integer. If present, this indicates the nth
occurrence of a specific day within the MONTHLY or YEARLY RRULE.
For example, within a MONTHLY rule, +1MO (or simply 1MO)
represents the first Monday within the month, whereas -1MO
represents the last Monday of the month. The numeric value in a
BYDAY rule part with the FREQ rule part set to YEARLY corresponds
to an offset within the month when the BYMONTH rule part is
present, and corresponds to an offset within the year when the
BYWEEKNO or BYMONTH rule parts are present. If an integer
modifier is not present, it means all days of this type within the
specified frequency. For example, within a MONTHLY rule, MO
represents all Mondays within the month. The BYDAY rule part MUST
NOT be specified with a numeric value when the FREQ rule part is
not set to MONTHLY or YEARLY. Furthermore, the BYDAY rule part
MUST NOT be specified with a numeric value with the FREQ rule part
set to YEARLY when the BYWEEKNO rule part is specified.
The BYMONTHDAY rule part specifies a COMMA-separated list of days
of the month. Valid values are 1 to 31 or -31 to -1. For
example, -10 represents the tenth to the last day of the month.
The BYMONTHDAY rule part MUST NOT be specified when the FREQ rule
part is set to WEEKLY.
The BYYEARDAY rule part specifies a COMMA-separated list of days
of the year. Valid values are 1 to 366 or -366 to -1. For
example, -1 represents the last day of the year (December 31st)
and -306 represents the 306th to the last day of the year (March
1st). The BYYEARDAY rule part MUST NOT be specified when the FREQ
rule part is set to DAILY, WEEKLY, or MONTHLY.
The BYWEEKNO rule part specifies a COMMA-separated list of
ordinals specifying weeks of the year. Valid values are 1 to 53
or -53 to -1. This corresponds to weeks according to week
numbering as defined in [ISO.8601.2004]. A week is defined as a
seven day period, starting on the day of the week defined to be
the week start (see WKST). Week number one of the calendar year
is the first week that contains at least four (4) days in that
calendar year. This rule part MUST NOT be used when the FREQ rule
part is set to anything other than YEARLY. For example, 3
represents the third week of the year.
Note: Assuming a Monday week start, week 53 can only occur when
Thursday is January 1 or if it is a leap year and Wednesday is
January 1.
The BYMONTH rule part specifies a COMMA-separated list of months
of the year. Valid values are 1 to 12.
The WKST rule part specifies the day on which the workweek starts.
Valid values are MO, TU, WE, TH, FR, SA, and SU. This is
significant when a WEEKLY RRULE has an interval greater than 1,
and a BYDAY rule part is specified. This is also significant when
in a YEARLY RRULE when a BYWEEKNO rule part is specified. The
default value is MO.
The BYSETPOS rule part specifies a COMMA-separated list of values
that corresponds to the nth occurrence within the set of
recurrence instances specified by the rule. BYSETPOS operates on
a set of recurrence instances in one interval of the recurrence
rule. For example, in a WEEKLY rule, the interval would be one
week A set of recurrence instances starts at the beginning of the
interval defined by the FREQ rule part. Valid values are 1 to 366
or -366 to -1. It MUST only be used in conjunction with another
BYxxx rule part. For example the last work day of the month
could be represented as:
FREQ=MONTHLY;BYDAY=MO,TU,WE,TH,FR;BYSETPOS=-1
Each BYSETPOS value can include a positive (+n) or negative (-n)
integer. If present, this indicates the nth occurrence of the
specific occurrence within the set of occurrences specified by the
rule.
Recurrence rules may generate recurrence instances with an invalid
date (e.g., February 30) or nonexistent local time (e.g., 1:30 AM
on a day where the local time is moved forward by an hour at 1:00
AM). Such recurrence instances MUST be ignored and MUST NOT be
counted as part of the recurrence set.
Information, not contained in the rule, necessary to determine the
various recurrence instance start time and dates are derived from
the Start Time (DTSTART) component attribute. For example,
FREQ=YEARLY;BYMONTH=1 doesn’t specify a specific day within the
month or a time. This information would be the same as what is
specified for DTSTART.
BYxxx rule parts modify the recurrence in some manner. BYxxx rule
parts for a period of time that is the same or greater than the
frequency generally reduce or limit the number of occurrences of
the recurrence generated. For example, FREQ=DAILY;BYMONTH=1
reduces the number of recurrence instances from all days (if
BYMONTH rule part is not present) to all days in January. BYxxx
rule parts for a period of time less than the frequency generally
increase or expand the number of occurrences of the recurrence.
For example, FREQ=YEARLY;BYMONTH=1,2 increases the number of
days within the yearly recurrence set from 1 (if BYMONTH rule part
is not present) to 2.
If multiple BYxxx rule parts are specified, then after evaluating
the specified FREQ and INTERVAL rule parts, the BYxxx rule parts
are applied to the current set of evaluated occurrences in the
following order: BYMONTH, BYWEEKNO, BYYEARDAY, BYMONTHDAY, BYDAY,
BYHOUR, BYMINUTE, BYSECOND and BYSETPOS; then COUNT and UNTIL are
evaluated.
The table below summarizes the dependency of BYxxx rule part
expand or limit behavior on the FREQ rule part value.
The term N/A means that the corresponding BYxxx rule part MUST
NOT be used with the corresponding FREQ value.
BYDAY has some special behavior depending on the FREQ value and
this is described in separate notes below the table.

for MONTHLY.
Note 2: Limit if BYYEARDAY or BYMONTHDAY is present; otherwise,

Here is an example of evaluating multiple BYxxx rule parts.
DTSTART;TZID=America/New_York:19970105T083000
RRULE:FREQ=YEARLY;INTERVAL=2;BYMONTH=1;BYDAY=SU;BYHOUR=8,9;
BYMINUTE=30
First, the INTERVAL=2 would be applied to FREQ=YEARLY to
arrive at every other year. Then, BYMONTH=1 would be applied
to arrive at every January, every other year. Then, BYDAY=SU
would be applied to arrive at every Sunday in January, every
other year. Then, BYHOUR=8,9 would be applied to arrive at
every Sunday in January at 8 AM and 9 AM, every other year.
Then, BYMINUTE=30 would be applied to arrive at every Sunday in
January at 8:30 AM and 9:30 AM, every other year. Then, lacking
information from RRULE, the second is derived from DTSTART, to
end up in every Sunday in January at 8:30:00 AM and 9:30:00 AM,
every other year. Similarly, if the BYMINUTE, BYHOUR, BYDAY,
BYMONTHDAY, or BYMONTH rule part were missing, the appropriate
minute, hour, day, or month would have been retrieved from the
DTSTART property.
If the computed local start time of a recurrence instance does not
exist, or occurs more than once, for the specified time zone, the
time of the recurrence instance is interpreted in the same manner
as an explicit DATE-TIME value describing that date and time, as
specified in Section 3.3.5.
No additional content value encoding (i.e., BACKSLASH character
encoding, see Section 3.3.11) is defined for this value type.

Describes a span of time.
From RFC5545:
If the property permits, multiple duration values are
specified by a COMMA-separated list of values. The format is
based on the [ISO.8601.2004] complete representation basic format
with designators for the duration of time. The format can
represent nominal durations (weeks and days) and accurate
durations (hours, minutes, and seconds). Note that unlike
[ISO.8601.2004], this value type doesn’t support the Y and M
designators to specify durations in terms of years and months.
The duration of a week or a day depends on its position in the
calendar. In the case of discontinuities in the time scale, such
as the change from standard time to daylight time and back, the
computation of the exact duration requires the subtraction or
addition of the change of duration of the discontinuity. Leap
seconds MUST NOT be considered when computing an exact duration.
When computing an exact duration, the greatest order time
components MUST be added first, that is, the number of days MUST
be added first, followed by the number of hours, number of
minutes, and number of seconds.
Negative durations are typically used to schedule an alarm to
trigger before an associated time (see Section 3.8.6.3).
No additional content value encoding (i.e., BACKSLASH character encoding, see Section 3.3.11) are defined for this value type.

Describes the action that should be taken when the alarm is signalled.
From RFC5545:
Each VALARM calendar component has a particular type
of action with which it is associated. This property specifies
the type of action. Applications MUST ignore alarms with x-name
and iana-token values they don’t recognize.
See PROPERTY
iclendar:text
Component to describe an alert or alarm that should be sent out.
Since there are three distinct grouping of properties for alarms in a calendar, in iClendar the alarms are split into three distinct subclasses:
AUDIO-ALARM
DISPLAY-ALARM
EMAIL-ALARM
You should use these classes instead of the ALARM superclass.
From RFC5545:
A VALARM calendar component is a grouping of
component properties that is a reminder or alarm for an event or a
to-do. For example, it may be used to define a reminder for a
pending event or an overdue to-do.
The VALARM calendar component MUST include the ACTION and
TRIGGER properties. The ACTION property further constrains
the VALARM calendar component in the following ways:
When the action is AUDIO, the alarm can also include one and
only one ATTACH property, which MUST point to a sound resource,
which is rendered when the alarm is triggered.
When the action is DISPLAY, the alarm MUST also include a
DESCRIPTION property, which contains the text to be displayed
when the alarm is triggered.
When the action is EMAIL, the alarm MUST include a DESCRIPTION
property, which contains the text to be used as the message body,
a SUMMARY property, which contains the text to be used as the
message subject, and one or more ATTENDEE properties, which
contain the email address of attendees to receive the message. It
can also include one or more ATTACH properties, which are
intended to be sent as message attachments. When the alarm is
triggered, the email message is sent.
The VALARM calendar component MUST only appear within either a
VEVENT or VTODO calendar component. VALARM calendar
components cannot be nested. Multiple mutually independent
VALARM calendar components can be specified for a single
VEVENT or VTODO calendar component.
The TRIGGER property specifies when the alarm will be triggered.
The TRIGGER property specifies a duration prior to the start of
an event or a to-do. The TRIGGER edge may be explicitly set to
be relative to the START or END of the event or to-do with the
RELATED parameter of the TRIGGER property. The TRIGGER
property value type can alternatively be set to an absolute
calendar date with UTC time.
In an alarm set to trigger on the START of an event or to-do,
the DTSTART property MUST be present in the associated event or
to-do. In an alarm in a VEVENT calendar component set to
trigger on the END of the event, either the DTEND property
MUST be present, or the DTSTART and DURATION properties MUST
both be present. In an alarm in a VTODO calendar component set
to trigger on the END of the to-do, either the DUE property
MUST be present, or the DTSTART and DURATION properties MUST
both be present.
The alarm can be defined such that it triggers repeatedly. A
definition of an alarm with a repeating trigger MUST include both
the DURATION and REPEAT properties. The DURATION property
specifies the delay period, after which the alarm will repeat.
The REPEAT property specifies the number of additional
repetitions that the alarm will be triggered. This repetition
count is in addition to the initial triggering of the alarm. Both
of these properties MUST be present in order to specify a
repeating alarm. If one of these two properties is absent, then
the alarm will not repeat beyond the initial trigger.
The ACTION property is used within the VALARM calendar
component to specify the type of action invoked when the alarm is
triggered. The VALARM properties provide enough information for
a specific action to be invoked. It is typically the
responsibility of a Calendar User Agent (CUA) to deliver the
alarm in the specified fashion. An ACTION property value of
AUDIO specifies an alarm that causes a sound to be played to alert
the user; DISPLAY specifies an alarm that causes a text message to
be displayed to the user; and EMAIL specifies an alarm that causes
an electronic email message to be delivered to one or more email
addresses.
In an AUDIO alarm, if the optional ATTACH property is included,
it MUST specify an audio sound resource. The intention is that
the sound will be played as the alarm effect. If an ATTACH
property is specified that does not refer to a sound resource, or
if the specified sound resource cannot be rendered (because its
format is unsupported, or because it cannot be retrieved), then
the CUA or other entity responsible for playing the sound may
choose a fallback action, such as playing a built-in default
sound, or playing no sound at all.
In a DISPLAY alarm, the intended alarm effect is for the text
value of the DESCRIPTION property to be displayed to the user.
In an EMAIL alarm, the intended alarm effect is for an email
message to be composed and delivered to all the addresses
specified by the ATTENDEE properties in the VALARM calendar
component. The DESCRIPTION property of the VALARM calendar
component MUST be used as the body text of the message, and the
SUMMARY property MUST be used as the subject text. Any ATTACH
properties in the VALARM calendar component SHOULD be sent as
attachments to the message.
Note: Implementations should carefully consider whether they
accept alarm components from untrusted sources, e.g., when
importing calendar objects from external sources. One
reasonable policy is to always ignore alarm components that the
calendar user has not set herself, or at least ask for
confirmation in such a case.

This property describes a file attachment to the component.
Must be an ATTACHMENT-VALUE
From RFC5545:
This property is used in VEVENT, VTODO, and
VJOURNAL calendar components to associate a resource (e.g.,
document) with the calendar component. This property is used in
VALARM calendar components to specify an audio sound resource or
an email message attachment. This property can be specified as a
URI pointing to a resource or as inline binary encoded content.
When this property is specified as inline binary encoded content,
calendar applications MAY attempt to guess the media type of the
resource via inspection of its content if and only if the media
type of the resource is not given by the FMTTYPE parameter. If
the media type remains unknown, calendar applications SHOULD treat
it as type "application/octet-stream".

This property describes a person who attends the calendar’s event.
Must be an ADDRESS.
From RFC5545:
This property MUST only be specified within calendar
components to specify participants, non-participants, and the
chair of a group-scheduled calendar entity. The property is
specified within an EMAIL category of the VALARM calendar
component to specify an email address that is to receive the email
type of iCalendar alarm.
The property parameter CN is for the common or displayable name
associated with the calendar address; ROLE, for the intended
role that the attendee will have in the calendar component;
PARTSTAT, for the status of the attendee’s participation;
RSVP, for indicating whether the favor of a reply is requested;
CUTYPE, to indicate the type of calendar user; MEMBER, to
indicate the groups that the attendee belongs to; DELEGATED-TO,
to indicate the calendar users that the original request was
delegated to; and DELEGATED-FROM, to indicate whom the request
was delegated from; SENT-BY, to indicate whom is acting on
behalf of the ATTENDEE; and DIR, to indicate the URI that
points to the directory information corresponding to the attendee.
These property parameters can be specified on an ATTENDEE
property in either a VEVENT, VTODO, or VJOURNAL calendar
component. They MUST NOT be specified in an ATTENDEE property
in a VFREEBUSY or VALARM calendar component. If the
LANGUAGE property parameter is specified, the identified
language applies to the CN parameter.
A recipient delegated a request MUST inherit the RSVP and ROLE
values from the attendee that delegated the request to them.
Multiple attendees can be specified by including multiple
ATTENDEE properties within the calendar component.

From RFC5545:
This property is used to specify categories or subtypes
of the calendar component. The categories are useful in searching
for a calendar component of a particular type and category.
Within the VEVENT, VTODO, or VJOURNAL calendar components,
more than one category can be specified as a COMMA-separated list
of categories.
See PROPERTY

This property describes the classification/confidentiality of an entry.
Must be a string or one of :PUBLIC :PRIVATE :CONFIDENTIAL.
From RFC5545:
An access classification is only one component of the
general security system within a calendar application. It
provides a method of capturing the scope of the access the
calendar owner intends for information within an individual
calendar entry. The access classification of an individual
iCalendar component is useful when measured along with the other
security components of a calendar system (e.g., calendar user
authentication, authorization, access rights, access role, etc.).
Hence, the semantics of the individual access classifications
cannot be completely defined by this memo alone. Additionally,
due to the blind nature of most exchange processes using this
memo, these access classifications cannot serve as an enforcement
statement for a system receiving an iCalendar object. Rather,
they provide a method for capturing the intention of the calendar
owner for the access to the calendar component. If not specified
in a component that allows this property, the default value is
PUBLIC. Applications MUST treat x-name and iana-token values they
don’t recognize the same way as they would the PRIVATE value.

iclendar:date-time
This property describes the percentage of completeness of the component.
Must be an integer in [0,100].
From RFC5545:
The property value is a positive integer between 0 and
100. A value of 0 indicates the to-do has not yet been started.
A value of 100 indicates that the to-do has been completed.
Integer values in between indicate the percent partially complete.
When a to-do is assigned to multiple individuals, the property
value indicates the percent complete for that portion of the to-do
assigned to the assignee or delegatee. For example, if a to-do is
assigned to both individuals A and B. A reply from A with a
percent complete of 70 indicates that A has completed 70% of
the to-do assigned to them. A reply from B with a percent
complete of 50 indicates B has completed 50% of the to-do
assigned to them.
See PROPERTY
(integer 0 100)
Base class of calendar components.
Components are property containers. Some components may also contain child-
components. A component may have either standard-slots, or property-slots.
Property slots will always contain, if bound, either a single property instance
or a list of property instances depending on the slot’s constraint.
A property slot can be set with either a property instance directly, or with
the value of a property instance. The value will automatically be encapsulated
in an appropriate property instance. Property slots are type and constraint
checked.

Component for a generic event kind of object in a calendar.
From RFC5545:
A VEVENT calendar component is a grouping of
component properties, possibly including VALARM calendar
components, that represents a scheduled amount of time on a
calendar. For example, it can be an activity; such as a one-hour
long, department meeting from 8:00 AM to 9:00 AM, tomorrow.
Generally, an event will take up time on an individual calendar.
Hence, the event will appear as an opaque interval in a search for
busy time. Alternately, the event can have its Time Transparency
set to TRANSPARENT in order to prevent blocking of the event in
searches for busy time.
The VEVENT is also the calendar component used to specify an anniversary or daily reminder within a calendar. These events have a DATE value type for the DTSTART property instead of the default value type of DATE-TIME. If such a VEVENT has a DTEND property, it MUST be specified as a DATE value also. The anniversary type of VEVENT can span more than one date (i.e., DTEND property value is set to a calendar date after the DTSTART property value). If such a VEVENT has a DURATION property, it MUST be specified as a dur-day or dur-week value.
The DTSTART property for a VEVENT specifies the inclusive
start of the event. For recurring events, it also specifies the
very first instance in the recurrence set. The DTEND property
for a VEVENT calendar component specifies the non-inclusive end
of the event. For cases where a VEVENT calendar component
specifies a DTSTART property with a DATE value type but no
DTEND nor DURATION property, the event’s duration is taken to
be one day. For cases where a VEVENT calendar component
specifies a DTSTART property with a DATE-TIME value type but no
DTEND property, the event ends on the same calendar date and
time of day specified by the DTSTART property.
The VEVENT calendar component cannot be nested within another
calendar component. However, VEVENT calendar components can be
related to each other or to a VTODO or to a VJOURNAL calendar
component with the RELATED-TO property.
See TRANSPARENCY
See END
See DURATION
See TASK-COMPONENT
This property describes an exceptional date on which the component does not recur.
Must be a DATE-TIME or a DATE.
From RFC5545:
The exception dates, if specified, are used in
computing the recurrence set. The recurrence set is the complete
set of recurrence instances for a calendar component. The
recurrence set is generated by considering the initial DTSTART
property along with the RRULE, RDATE, and EXDATE properties
contained within the recurring component. The DTSTART property
defines the first instance in the recurrence set. The DTSTART
property value SHOULD match the pattern of the recurrence rule, if
specified. The recurrence set generated with a DTSTART property
value that doesn’t match the pattern of the rule is undefined.
The final recurrence set is generated by gathering all of the
start DATE-TIME values generated by any of the specified RRULE
and RDATE properties, and then excluding any start DATE-TIME
values specified by EXDATE properties. This implies that start
DATE-TIME values specified by EXDATE properties take precedence
over those specified by inclusion properties (i.e., RDATE and
RRULE). When duplicate instances are generated by the RRULE
and RDATE properties, only one recurrence is considered.
Duplicate instances are ignored.
The EXDATE property can be used to exclude the value specified
in DTSTART. However, in such cases, the original DTSTART date
MUST still be maintained by the calendaring and scheduling system
because the original DTSTART value has inherent usage
dependencies by other properties such as the RECURRENCE-ID.

Component to describe a region of time during which a person is free or busy.
From RFC5545:
A VFREEBUSY calendar component is a grouping of
component properties that represents either a request for free or
busy time information, a reply to a request for free or busy time
information, or a published set of busy time information.
When used to request free/busy time information, the ATTENDEE
property specifies the calendar users whose free/busy time is
being requested; the ORGANIZER property specifies the calendar
user who is requesting the free/busy time; the DTSTART and
DTEND properties specify the window of time for which the free/
busy time is being requested; the UID and DTSTAMP properties
are specified to assist in proper sequencing of multiple free/busy
time requests.
When used to reply to a request for free/busy time, the ATTENDEE
property specifies the calendar user responding to the free/busy
time request; the ORGANIZER property specifies the calendar user
that originally requested the free/busy time; the FREEBUSY
property specifies the free/busy time information (if it exists);
and the UID and DTSTAMP properties are specified to assist in
proper sequencing of multiple free/busy time replies.
When used to publish busy time, the ORGANIZER property specifies
the calendar user associated with the published busy time; the
DTSTART and DTEND properties specify an inclusive time window
that surrounds the busy time information; the FREEBUSY property
specifies the published busy time information; and the DTSTAMP
property specifies the DATE-TIME that iCalendar object was
created.
The VFREEBUSY calendar component cannot be nested within another
calendar component. Multiple VFREEBUSY calendar components can
be specified within an iCalendar object. This permits the
grouping of free/busy information into logical collections, such
as monthly groups of busy time information.
The VFREEBUSY calendar component is intended for use in
iCalendar object methods involving requests for free time,
requests for busy time, requests for both free and busy, and the
associated replies.
Free/Busy information is represented with the FREEBUSY property.
This property provides a terse representation of time periods.
One or more FREEBUSY properties can be specified in the
VFREEBUSY calendar component.
When present in a VFREEBUSY calendar component, the DTSTART
and DTEND properties SHOULD be specified prior to any FREEBUSY
properties.
The recurrence properties (RRULE, RDATE, EXDATE) are not
permitted within a VFREEBUSY calendar component. Any recurring
events are resolved into their individual busy time periods using
the FREEBUSY property.

This property describes a free or busy time period.
Must be a PERIOD.
From RFC5545:
These time periods can be specified as either a start
and end DATE-TIME or a start DATE-TIME and DURATION. The date and
time MUST be a UTC time format.
FREEBUSY properties within the VFREEBUSY calendar component
SHOULD be sorted in ascending order, based on start time and then
end time, with the earliest periods first.
The FREEBUSY property can specify more than one value, separated
by the COMMA character. In such cases, the FREEBUSY property
values MUST all be of the same FBTYPE property parameter type
(e.g., all values of a particular FBTYPE listed together in a
single property).

This property describes a geographic location where the component takes place.
Must be a GEO.
From RFC5545:
This property value specifies latitude and longitude,
in that order (i.e., LAT LON ordering). The longitude
represents the location east or west of the prime meridian as a
positive or negative real number, respectively. The longitude and
latitude values MAY be specified up to six decimal places, which
will allow for accuracy to within one meter of geographical
position. Receiving applications MUST accept values of this
precision and MAY truncate values of greater precision.
Values for latitude and longitude shall be expressed as decimal
fractions of degrees. Whole degrees of latitude shall be
represented by a two-digit decimal number ranging from 0 through
90. Whole degrees of longitude shall be represented by a decimal
number ranging from 0 through 180. When a decimal fraction of a
degree is specified, it shall be separated from the whole number
of degrees by a decimal point.
Latitudes north of the equator shall be specified by a plus sign
(+), or by the absence of a minus sign (-), preceding the digits
designating degrees. Latitudes south of the Equator shall be
designated by a minus sign (-) preceding the digits designating
degrees. A point on the Equator shall be assigned to the Northern
Hemisphere.
Longitudes east of the prime meridian shall be specified by a plus
sign (+), or by the absence of a minus sign (-), preceding the
digits designating degrees. Longitudes west of the meridian shall
be designated by minus sign (-) preceding the digits designating
degrees. A point on the prime meridian shall be assigned to the
Eastern Hemisphere. A point on the 180th meridian shall be
assigned to the Western Hemisphere. One exception to this last
convention is permitted. For the special condition of describing
a band of latitude around the earth, the East Bounding Coordinate
data element shall be assigned the value +180 (180) degrees.
Any spatial address with a latitude of +90 (90) or -90 degrees
will specify the position at the North or South Pole,
respectively. The component for longitude may have any legal
value.
With the exception of the special condition described above, this
form is specified in [ANSI INCITS 61-1986].
The simple formula for converting degrees-minutes-seconds into
decimal degrees is:
decimal = degrees + minutes/60 + seconds/3600.

iclendar:geo
Component describing a generic journal entry in a calendar.
From RFC5545:
A VJOURNAL calendar component is a grouping of
component properties that represent one or more descriptive text
notes associated with a particular calendar date. The DTSTART
property is used to specify the calendar date with which the
journal entry is associated. Generally, it will have a DATE value
data type, but it can also be used to specify a DATE-TIME value
data type. Examples of a journal entry include a daily record of
a legislative body or a journal entry of individual telephone
contacts for the day or an ordered list of accomplishments for the
day. The VJOURNAL calendar component can also be used to
associate a document with a calendar date.
The VJOURNAL calendar component does not take up time on a
calendar. Hence, it does not play a role in free or busy time
searches – it is as though it has a time transparency value of
TRANSPARENT. It is transparent to any such searches.
The VJOURNAL calendar component cannot be nested within another
calendar component. However, VJOURNAL calendar components can
be related to each other or to a VEVENT or to a VTODO calendar
component, with the RELATED-TO property.

From RFC5545:
Specific venues such as conference or meeting rooms may
be explicitly specified using this property. An alternate
representation may be specified that is a URI that points to
directory information with more structured specification of the
location. For example, the alternate representation may specify
either an LDAP URL [RFC4516] pointing to an LDAP server entry or a
CID URL [RFC2392] pointing to a MIME body part containing a
Virtual-Information Card (vCard) [RFC2426] for the location.

This property describes where the time zone is offset from.
Must be an UTC-OFFSET.
From RFC5545:
This property specifies the offset that is in use prior
to this time observance. It is used to calculate the absolute
time at which the transition to a given observance takes place.
This property MUST only be specified in a VTIMEZONE calendar
component. A VTIMEZONE calendar component MUST include this
property. The property value is a signed numeric indicating the
number of hours and possibly minutes from UTC. Positive numbers
represent time zones east of the prime meridian, or ahead of UTC.
Negative numbers represent time zones west of the prime meridian,
or behind UTC.

This property describes the organizer of the component.
Must be an ADDRESS.
From RFC5545:
This property is specified within the VEVENT,
VTODO, and VJOURNAL calendar components to specify the
organizer of a group-scheduled calendar entity. The property is
specified within the VFREEBUSY calendar component to specify the
calendar user requesting the free or busy time. When publishing a
VFREEBUSY calendar component, the property is used to specify
the calendar that the published busy time came from.
The property has the property parameters CN, for specifying the
common or display name associated with the Organizer, DIR, for
specifying a pointer to the directory information associated with
the Organizer, SENT-BY, for specifying another calendar user
that is acting on behalf of the Organizer. The non-standard
parameters may also be specified on this property. If the
LANGUAGE property parameter is specified, the identified
language applies to the CN parameter value.

This property describes the priority of the component.
Must be an integer in [0,9].
From RFC5545:
This priority is specified as an integer in the range 0
to 9. A value of 0 specifies an undefined priority. A value of 1
is the highest priority. A value of 2 is the second highest
priority. Subsequent numbers specify a decreasing ordinal
priority. A value of 9 is the lowest priority.
A CUA with a three-level priority scheme of HIGH, MEDIUM, and
LOW is mapped into this property such that a property value in
the range of 1 to 4 specifies HIGH priority. A value of 5 is
the normal or MEDIUM priority. A value in the range of 6 to 9
is LOW priority.
A CUA with a priority schema of A1, A2, A3, B1, B2, ...,
C3 is mapped into this property such that a property value of 1
specifies A1, a property value of 2 specifies A2, a property
value of 3 specifies A3, and so forth up to a property value of
9 specifies C3.
Other integer values are reserved for future use.
Within a VEVENT calendar component, this property specifies a
priority for the event. This property may be useful when more
than one event is scheduled for a given time period.
Within a VTODO calendar component, this property specified a
priority for the to-do. This property is useful in prioritizing
multiple action items for a given time period.

This property describes a specific date on which the component recurs.
Must be a DATE-TIME or DATE.
From RFC5545:
This property can appear along with the RRULE
property to define an aggregate set of repeating occurrences.
When they both appear in a recurring component, the recurrence
instances are defined by the union of occurrences defined by both
the RDATE and RRULE.
The recurrence dates, if specified, are used in computing the
recurrence set. The recurrence set is the complete set of
recurrence instances for a calendar component. The recurrence set
is generated by considering the initial DTSTART property along
with the RRULE, RDATE, and EXDATE properties contained
within the recurring component. The DTSTART property defines
the first instance in the recurrence set. The DTSTART property
value SHOULD match the pattern of the recurrence rule, if
specified. The recurrence set generated with a DTSTART property
value that doesn’t match the pattern of the rule is undefined.
The final recurrence set is generated by gathering all of the
start DATE-TIME values generated by any of the specified RRULE
and RDATE properties, and then excluding any start DATE-TIME
values specified by EXDATE properties. This implies that start
DATE-TIME values specified by EXDATE properties take precedence
over those specified by inclusion properties (i.e., RDATE and
RRULE). Where duplicate instances are generated by the RRULE
and RDATE properties, only one recurrence is considered.
Duplicate instances are ignored.

This property allows referencing a specific recurrence date.
Must be a DATE-TIME or a DATE.
From RFC5545:
The full range of calendar components specified by a
recurrence set is referenced by referring to just the UID
property value corresponding to the calendar component. The
RECURRENCE-ID property allows the reference to an individual
instance within the recurrence set.
If the value of the DTSTART property is a DATE type value, then the value MUST be the calendar date for the recurrence instance.
The DATE-TIME value is set to the time when the original
recurrence instance would occur; meaning that if the intent is to
change a Friday meeting to Thursday, the DATE-TIME is still set to
the original Friday meeting.
The RECURRENCE-ID property is used in conjunction with the UID
and SEQUENCE properties to identify a particular instance of a
recurring event, to-do, or journal. For a given pair of UID and
SEQUENCE property values, the RECURRENCE-ID value for a
recurrence instance is fixed.
The RANGE parameter is used to specify the effective range of
recurrence instances from the instance specified by the
RECURRENCE-ID property value. The value for the range parameter
can only be THISANDFUTURE to indicate a range defined by the
given recurrence instance and all subsequent instances.
Subsequent instances are determined by their RECURRENCE-ID value
and not their current scheduled start time. Subsequent instances
defined in separate components are not impacted by the given
recurrence instance. When the given recurrence instance is
rescheduled, all subsequent instances are also rescheduled by the
same time difference. For instance, if the given recurrence
instance is rescheduled to start 2 hours later, then all
subsequent instances are also rescheduled 2 hours later.
Similarly, if the duration of the given recurrence instance is
modified, then all subsequence instances are also modified to have
this same duration.
Note: The RANGE parameter may not be appropriate to
reschedule specific subsequent instances of complex recurring
calendar component. Assuming an unbounded recurring calendar
component scheduled to occur on Mondays and Wednesdays, the
RANGE parameter could not be used to reschedule only the
future Monday instances to occur on Tuesday instead. In such
cases, the calendar application could simply truncate the
unbounded recurring calendar component (i.e., with the COUNT
or UNTIL rule parts), and create two new unbounded recurring
calendar components for the future instances.

This property describes a generic rule by which the component recurs.
Must be a RECURRENCE.
From RFC5545:
The recurrence rule, if specified, is used in computing
the recurrence set. The recurrence set is the complete set of
recurrence instances for a calendar component. The recurrence set
is generated by considering the initial DTSTART property along
with the RRULE, RDATE, and EXDATE properties contained
within the recurring component. The DTSTART property defines
the first instance in the recurrence set. The DTSTART property
value SHOULD be synchronized with the recurrence rule, if
specified. The recurrence set generated with a DTSTART property
value not synchronized with the recurrence rule is undefined. The
final recurrence set is generated by gathering all of the start
DATE-TIME values generated by any of the specified RRULE and
RDATE properties, and then excluding any start DATE-TIME values
specified by EXDATE properties. This implies that start DATE-
TIME values specified by EXDATE properties take precedence over
those specified by inclusion properties (i.e., RDATE and
RRULE). Where duplicate instances are generated by the RRULE
and RDATE properties, only one recurrence is considered.
Duplicate instances are ignored.
The DTSTART property specified within the iCalendar object
defines the first instance of the recurrence. In most cases, a
DTSTART property of DATE-TIME value type used with a recurrence
rule, should be specified as a date with local time and time zone
reference to make sure all the recurrence instances start at the
same local time regardless of time zone changes.
If the duration of the recurring component is specified with the
DTEND or DUE property, then the same exact duration will apply
to all the members of the generated recurrence set. Else, if the
duration of the recurring component is specified with the
DURATION property, then the same nominal duration will apply to
all the members of the generated recurrence set and the exact
duration of each recurrence instance will depend on its specific
start time. For example, recurrence instances of a nominal
duration of one day will have an exact duration of more or less
than 24 hours on a day where a time zone shift occurs. The
duration of a specific recurrence may be modified in an exception
component or simply by using an RDATE property of PERIOD value
type.

iclendar:recurrence
This property defines a related component.
Must be a TEXT.
From RFC5545:
The property value consists of the persistent, globally
unique identifier of another calendar component. This value would
be represented in a calendar component by the UID property.
By default, the property value points to another calendar
component that has a PARENT relationship to the referencing
object. The RELTYPE property parameter is used to either
explicitly state the default PARENT relationship type to the
referenced calendar component or to override the default PARENT
relationship type and specify either a CHILD or SIBLING
relationship. The PARENT relationship indicates that the calendar
component is a subordinate of the referenced calendar component.
The CHILD relationship indicates that the calendar component is a
superior of the referenced calendar component. The SIBLING
relationship indicates that the calendar component is a peer of
the referenced calendar component.
Changes to a calendar component referenced by this property can
have an implicit impact on the related calendar component. For
example, if a group event changes its start or end date or time,
then the related, dependent events will need to have their start
and end dates changed in a corresponding way. Similarly, if a
PARENT calendar component is cancelled or deleted, then there is
an implied impact to the related CHILD calendar components. This
property is intended only to provide information on the
relationship of calendar components. It is up to the target
calendar system to maintain any property implications of this
relationship.

When a calendar component is created, its sequence
number is 0. It is monotonically incremented by the "Organizer’s"
CUA each time the "Organizer" makes a significant revision to the
calendar component.
The "Organizer" includes this property in an iCalendar object that
it sends to an "Attendee" to specify the current version of the
calendar component.
The "Attendee" includes this property in an iCalendar object that
it sends to the "Organizer" to specify the version of the calendar
component to which the "Attendee" is referring.
A change to the sequence number is not the mechanism that an
"Organizer" uses to request a response from the "Attendees". The
"RSVP" parameter on the "ATTENDEE" property is used by the
"Organizer" to indicate that a response from the "Attendees" is
requested.
Recurrence instances of a recurring component MAY have different
sequence numbers.

property will assist in the proper sequencing of messages
containing iCalendar objects.
In the case of an iCalendar object that specifies a METHOD
property, this property differs from the CREATED and LAST-
MODIFIED properties. These two properties are used to specify
when the particular calendar data in the calendar store was
created and last modified. This is different than when the
iCalendar object representation of the calendar service

Component to describe a grouping of parts to describe a time zone.
From RFC5545:
A time zone is unambiguously defined by the set of time
measurement rules determined by the governing body for a given
geographic area. These rules describe, at a minimum, the base
offset from UTC for the time zone, often referred to as the
Standard Time offset. Many locations adjust their Standard Time
forward or backward by one hour, in order to accommodate seasonal
changes in number of daylight hours, often referred to as Daylight
Saving Time. Some locations adjust their time by a fraction of an
hour. Standard Time is also known as Winter Time. Daylight
Saving Time is also known as Advanced Time, Summer Time, or Legal
Time in certain countries. The following table shows the changes
in time zone rules in effect for New York City starting from 1967.
Each line represents a description or rule for a particular
observance.

Note: The specification of a global time zone registry is not
addressed by this document and is left for future study.
However, implementers may find the TZ database [TZDB] a useful
reference. It is an informal, public-domain collection of time
zone information, which is currently being maintained by
volunteer Internet participants, and is used in several
operating systems. This database contains current and
historical time zone information for a wide variety of
locations around the globe; it provides a time zone identifier
for every unique time zone rule set in actual use since 1970,
with historical data going back to the introduction of standard
time.
Interoperability between two calendaring and scheduling
applications, especially for recurring events, to-dos or journal
entries, is dependent on the ability to capture and convey date
and time information in an unambiguous format. The specification
of current time zone information is integral to this behavior.
If present, the VTIMEZONE calendar component defines the set of
Standard Time and Daylight Saving Time observances (or rules) for
a particular time zone for a given interval of time. The
VTIMEZONE calendar component cannot be nested within other
calendar components. Multiple VTIMEZONE calendar components can
exist in an iCalendar object. In this situation, each VTIMEZONE
MUST represent a unique time zone definition. This is necessary
for some classes of events, such as airline flights, that start in
one time zone and end in another.
The VTIMEZONE calendar component MUST include the TZID
property and at least one definition of a STANDARD or DAYLIGHT
sub-component. The STANDARD or DAYLIGHT sub-component MUST
include the DTSTART, TZOFFSETFROM, and TZOFFSETTO
properties.
An individual VTIMEZONE calendar component MUST be specified for
each unique TZID parameter value specified in the iCalendar
object. In addition, a VTIMEZONE calendar component, referred
to by a recurring calendar component, MUST provide valid time zone
information for all recurrence instances.
Each VTIMEZONE calendar component consists of a collection of
one or more sub-components that describe the rule for a particular
observance (either a Standard Time or a Daylight Saving Time
observance). The STANDARD sub-component consists of a
collection of properties that describe Standard Time. The
DAYLIGHT sub-component consists of a collection of properties
that describe Daylight Saving Time. In general, this collection
of properties consists of:
* the first onset DATE-TIME for the observance;
* the last onset DATE-TIME for the observance, if a last onset is
known;
* the offset to be applied for the observance;
* a rule that describes the day and time when the observance
takes effect;
* an optional name for the observance.
For a given time zone, there may be multiple unique definitions of
the observances over a period of time. Each observance is
described using either a STANDARD or DAYLIGHT sub-component.
The collection of these sub-components is used to describe the
time zone for a given period of time. The offset to apply at any
given time is found by locating the observance that has the last
onset date and time before the time in question, and using the
offset value from that observance.
The top-level properties in a VTIMEZONE calendar component are:
The mandatory TZID property is a text value that uniquely
identifies the VTIMEZONE calendar component within the scope of
an iCalendar object.
The optional LAST-MODIFIED property is a UTC value that
specifies the date and time that this time zone definition was
last updated.
The optional TZURL property is a url value that points to a
published VTIMEZONE definition. TZURL SHOULD refer to a
resource that is accessible by anyone who might need to interpret
the object. This SHOULD NOT normally be a file URL or other URL
that is not widely accessible.
The collection of properties that are used to define the
STANDARD and DAYLIGHT sub-components include:
The mandatory DTSTART property gives the effective onset date
and local time for the time zone sub-component definition.
DTSTART in this usage MUST be specified as a date with a local
time value.
The mandatory TZOFFSETFROM property gives the UTC offset that is
in use when the onset of this time zone observance begins.
TZOFFSETFROM is combined with DTSTART to define the effective
onset for the time zone sub-component definition. For example,
the following represents the time at which the observance of
Standard Time took effect in Fall 1967 for New York City:
DTSTART:19671029T020000
TZOFFSETFROM:-0400
The mandatory TZOFFSETTO property gives the UTC offset for the
time zone sub-component (Standard Time or Daylight Saving Time)
when this observance is in use.
The optional TZNAME property is the customary name for the time
zone. This could be used for displaying dates.
The onset DATE-TIME values for the observance defined by the time
zone sub-component is defined by the DTSTART, RRULE, and
RDATE properties.
The RRULE property defines the recurrence rule for the onset of
the observance defined by this time zone sub-component. Some
specific requirements for the usage of RRULE for this purpose
include:
* If observance is known to have an effective end date, the
UNTIL recurrence rule parameter MUST be used to specify the
last valid onset of this observance (i.e., the UNTIL DATE-TIME
will be equal to the last instance generated by the recurrence
pattern). It MUST be specified in UTC time.
* The DTSTART and the TZOFFSETFROM properties MUST be used
when generating the onset DATE-TIME values (instances) from the
RRULE.
The RDATE property can also be used to define the onset of the
observance by giving the individual onset date and times. RDATE
in this usage MUST be specified as a date with local time value,
relative to the UTC offset specified in the TZOFFSETFROM
property.
The optional COMMENT property is also allowed for descriptive
explanatory text.

This is a child component describing a part of a time zone.
Since time zone components can take on two forms, iClendar implements the
following two subclasses that should be used instead of this:
TIME-ZONE-STANDARD
TIME-ZONE-DAYLIGHT

Component representing a todo item in a calendar.
From RFC5545:
A VTODO calendar component is a grouping of component
properties and possibly VALARM calendar components that
represent an action-item or assignment. For example, it can be
used to represent an item of work assigned to an individual; such
as "turn in travel expense today".
The VTODO calendar component cannot be nested within another
calendar component. However, VTODO calendar components can be
related to each other or to a VEVENT or to a VJOURNAL calendar
component with the RELATED-TO property.
A VTODO calendar component without the DTSTART and DUE (or
DURATION) properties specifies a to-do that will be associated
with each successive calendar date, until it is completed.

See DUE
See DURATION
See TASK-COMPONENT
This property describes whether the component takes up physical time.
Must be a string or one of :OPAQUE :TRANSPARENT.
From RFC5545:
Time Transparency is the characteristic of an event
that determines whether it appears to consume time on a calendar.
Events that consume actual time for the individual or resource
associated with the calendar SHOULD be recorded as OPAQUE,
allowing them to be detected by free/busy time searches. Other
events, which do not take up the individual’s (or resource’s) time
SHOULD be recorded as TRANSPARENT, making them invisible to free/
busy time searches.
See PROPERTY
(or string (member :opaque :transparent))
This property describes the transport method by which the calendar is sent.
Must be a TEXT.
From RFC5545:
When used in a MIME message entity, the value of this
property MUST be the same as the Content-Type method parameter
value. If either the METHOD property or the Content-Type
method parameter is specified, then the other MUST also be
specified.
No methods are defined by this specification. This is the subject
of other specifications, such as the iCalendar Transport-
independent Interoperability Protocol (iTIP) defined by [2446bis].
If this property is not present in the iCalendar object, then a
scheduling transaction MUST NOT be assumed. In such cases, the
iCalendar object is merely being used to transport a snapshot of

This property describes the trigger for an alarm.
Must be a TIME-SPAN or a DATE-TIME.
From RFC5545:
This property defines when an alarm will trigger. The
default value type is DURATION, specifying a relative time for the
trigger of the alarm. The default duration is relative to the
start of an event or to-do with which the alarm is associated.
The duration can be explicitly set to trigger from either the end
or the start of the associated event or to-do with the RELATED
parameter. A value of START will set the alarm to trigger off the
start of the associated event or to-do. A value of END will set
the alarm to trigger off the end of the associated event or to-do.
Either a positive or negative duration may be specified for the
TRIGGER property. An alarm with a positive duration is
triggered after the associated start or end of the event or to-do.
An alarm with a negative duration is triggered before the
associated start or end of the event or to-do.
The RELATED property parameter is not valid if the value type of the property is set to DATE-TIME (i.e., for an absolute date and time alarm trigger). If a value type of DATE-TIME is specified, then the property value MUST be specified in the UTC time format. If an absolute trigger is specified on an alarm for a recurring event or to-do, then the alarm will only trigger for the specified absolute DATE-TIME, along with any specified repeating instances.
If the trigger is set relative to START, then the DTSTART
property MUST be present in the associated VEVENT or VTODO
calendar component. If an alarm is specified for an event with
the trigger set relative to the END, then the DTEND property or
the DTSTART and DURATION properties MUST be present in the
associated VEVENT calendar component. If the alarm is specified
for a to-do with a trigger set relative to the END, then either
the DUE property or the DTSTART and DURATION properties
MUST be present in the associated VTODO calendar component.
Alarms specified in an event or to-do that is defined in terms of
a DATE value type will be triggered relative to 00:00:00 of the
user’s configured time zone on the specified date, or relative to
00:00:00 UTC on the specified date if no configured time zone can
be found for the user. For example, if DTSTART is a DATE value
set to 19980205 then the duration trigger will be relative to
19980205T000000 America/New_York for a user configured with the
America/New_York time zone.

This property assigns a unique ID to the time zone to reference it by.
Must be a TEXT.
From RFC5545:
This is the label by which a time zone calendar
component is referenced by any iCalendar properties whose value
type is either DATE-TIME or TIME and not intended to specify a UTC
or a floating time. The presence of the SOLIDUS character as a
prefix, indicates that this TZID represents an unique ID in a
globally defined time zone registry (when such registry is
defined).
Note: This document does not define a naming convention for
time zone identifiers. Implementers may want to use the naming
conventions defined in existing time zone specifications such
as the public-domain TZ database [TZDB]. The specification of
globally unique time zone identifiers is not addressed by this
document and is left for future study.

iclendar:text
This property describes a name for the time zone.
Must be a TEXT.
From RFC5545:
This property specifies a customary name that can be
used when displaying dates that occur during the observance
defined by the time zone sub-component.
See PROPERTY

This property describes a network location where the time zone is described.
Must be a URI.
From RFC5545:
This property provides a means for a VTIMEZONE
component to point to a network location that can be used to
retrieve an up-to-date version of itself. This provides a hook to
handle changes government bodies impose upon time zone
definitions. Retrieval of this resource results in an iCalendar
object containing a single VTIMEZONE component and a METHOD
property set to PUBLISH.
See PROPERTY
See URI
iclendar:uri
This property describes a globally unique identifier for the component.
Must be a TEXT.
From RFC5545:
The UID itself MUST be a globally unique identifier.
The generator of the identifier MUST guarantee that the identifier
is unique. There are several algorithms that can be used to
accomplish this. A good method to assure uniqueness is to put the
domain name or a domain literal IP address of the host on which
the identifier was created on the right-hand side of an @, and
on the left-hand side, put a combination of the current calendar
date and time of day (i.e., formatted in as a DATE-TIME value)
along with some other currently unique (perhaps sequential)
identifier available on the system (for example, a process id
number). Using a DATE-TIME value on the left-hand side and a
domain name or domain literal on the right-hand side makes it
possible to guarantee uniqueness since no two hosts should be
using the same domain name or IP address at the same time. Though
other algorithms will work, it is RECOMMENDED that the right-hand
side contain some domain identifier (either of the host itself or
otherwise) such that the generator of the message identifier can
guarantee the uniqueness of the left-hand side within the scope of
that domain.
This is the method for correlating scheduling messages with the
referenced VEVENT, VTODO, or VJOURNAL calendar component.
The full range of calendar components specified by a recurrence
set is referenced by referring to just the UID property value
corresponding to the calendar component. The RECURRENCE-ID
property allows the reference to an individual instance within the
recurrence set.
This property is an important method for group-scheduling
applications to match requests with later replies, modifications,
or deletion requests. Calendaring and scheduling applications
MUST generate this property in VEVENT, VTODO, and VJOURNAL
calendar components to assure interoperability with other group-
scheduling applications. This identifier is created by the
calendar system that generates an iCalendar object.
Implementations MUST be able to receive and persist values of at
least 255 octets for this property, but they MUST NOT truncate
values in the middle of a UTF-8 multi-octet sequence.

iclendar:text
This property describes a URL where a rendered representation of the component resides.
Must be a URI.
From RFC5545:
This property may be used in a calendar component to
convey a location where a more dynamic rendition of the calendar
information associated with the calendar component can be found.
This memo does not attempt to standardize the form of the URI, nor
the format of the resource pointed to by the property value. If
the URL property and Content-Location MIME header are both
specified, they MUST point to the same resource.
