A small Common Lisp script to aid in the counting of the days and weeks from Pesach to Shavuot.
A discussion of the purpose and requirements of this script can be found at this blog article, but here is the essential summary.
There are two biblical feasts called Pesach and Shavuot, where the latter is fifty days after the former. There is a biblical commandment to count the days, the weeks and the weekly Sabbaths which occur between 16 Aviv (the day after Pesach) and the day of Shavuot, fifty days later.
The Bible gives a few instructions on the counting requirements:
We take it that to do this counting, the intention is that it be done each day until the eve of Shavuot arrives; and therein lies the problem which this program is meant to solve: a single person performing this count manually each day may possibly be error prone. It's handy to have a convenient confirmation that one has not skipped or doubled up on a day.
