* moved to: [[https://codeberg.org/cage/easter-gauss/]]

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
