Summary of zip file contents:

The package provides
-- C source              eac.c
-- Pascal source         eas.pas
-- DOS executable file   eas.com
-- documentation file    eas.doc

for Easter dates New & Old Style for any year AD, along with days

etc), for direct comparison with traditional Easter tables -- both
for the Gregorian (New Style) calendar and its Easter cycle, and
for the Julian (Old Style) calendar and its corresponding Easter
cycle.

The doc file eas.doc reproduces historic source material,
gives explanation of the complete calendar rules as implemented by
the source files, and test data.
