Aga and WhiteTiger,
In this thread back in June 2003, each of you posted code for the calculation of Easter Sunday. At the time, I only did some spot checks on the output of your solutions.
Today, October 19, 2006, I wrote a program to be able to test Easter Sunday algorithms against one of two proven algorithms (one of mine and the other by Antoni Gual).
I searched for your algorithms submitted in June 2003, and incorporated them into the test program. These are the results:
Aga's algorithm: For the years from 1600 to 9999, there were 61 invalid dates for Easter generated. Curiously, all the bad dates were in the month of May.
WhiteTiger algorithm: produced the Easter dates 100% perfectly for years 1600 to 9999.
"better late than never."
Regards..... Moneo
