Easter Sunday Calculates the Easter Sunday of a Given Year
ostersonntag.pl (noart download section) runs well with SWI and GNU Prolog and maybe with other not tested Prolog Systems, because it doesn't use specific predicates.
The algorithm (Gauß) is from the Physikalisch technischen Bundesanstalt (PTB). www.ptb.de
This little program is under GNU General Public License (GPL) and therefore free to copy and to alter.
As usual in GNU Prolog, you can use
gplc --min-size ostersonntag.pl
