This package exports a single method, ~easter-date:easter-date~. The method takes a single argument and is specialized on integer or an istance of a [[https://local-time.common-lisp.dev/][timestamp class from the local-date library]]. When called, the methods performs the algorithm invented by [[https://en.wikipedia.org/wiki/Date_of_Easter#Gauss's_Easter_algorithm][Gauss]] to calculate the Easter date and returns two values: the day (starting from ~1~) and the month (~3~ or ~4~) of the Easter. Examples given below: #+BEGIN_SRC lisp (easter-date:easter-date (local-time:now)) ; the date for the Easter in the current year (easter-date:easter-date 2022) ; the date for the Easter for the year 2022 (values 17 4) #+END_SRC * LICENSE Copyright © 2022 cage Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the “Software”), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
