We Eastern Orthodox need to acknowledge that the science of Astronomy exists, and agree on one date for Easter ! Take the calculations away from the monks ...
> Note that is does not calculate the Eastern Orthodox (Julian Calendar) Easter.
Technically, the Eastern Orthorodx is using the older calendaring system and just didn't update to the newer Gregorian calendar. So I guess you could say the Eastern Orthodox is more traditional and the Roman Catholic one is more astrologically correct.
I was actually surprised how difficult it was to do the Roman Catholic calendar and weary of going through all of that for the Eastern Orthodox one. But maybe someone will do that and add it to the file.
By the way, this is the version 1 of the file and you might want to see my later post with Version 2 that has the calculation both by script and by calculation.
