 Subj: EASTER IDENTIFICATION         Status: PUBLIC MESSAGE

 Does anyone have a nifty algorithm that will give the month and day of
 Easter given the year?  (I can't really believe that such a thing is
 possible given the definition of Easter.)  If not, does anyone have a
 pointer to a table of the Easter dates from, say, 1900 to 2080?  (If and
 when and I get this, I'll upload the table--at 360 bytes at the outside,
 it is probably smaller than the algorithm--and that's allowing a byte
 for month and a byte for day.  And since we know Easter ranges from
 March 22 through April 25, we could do it in one byte:  022 thru 031 for
 the March dates, say, and 101 through 125 for the April dates, with the
 year used as the offset into the table (after subtracting 1900).)
