Compute the date for Easter.
For TI-85.




Program:  EASTER
Author:   John P. Powers  (jpp@cpdvax.csc.ti.com)

Program EASTER computes the date for Easter for a given year.

The program first prompts for the year then returns the date for Easter of
that year as a list of {month day year}.

For example:
  EASTER
  Year: 1994
             {4 3 1994}

  Easter of 1994 occurs on April 3.

Sorry, I don't know where this algorithm comes from or for the range of years
the formula works. I suspect it's good for this century and the next but I
haven't compared it against known Easters in earlier or later centuries.
