I previously posted this and someone asked me for this file, but with it as a single calculation field instead of a script. So here is version 2 with both methods.
Well, it is that time of year and I was having to do some date calucations based on Easter (e.g., Mardis Gras, etc.).
Attached is a FM file with a script that will calculate Western (Roman Catholic) Gregorian Easter Dates for years 326-2599. Note that is does not calculate the Eastern Orthodox (Julian Calendar) Easter.
Since I had to do this work and thought others might be interested, here it is. You would think it was an easy calculation, but the script is not so simple. Oh well, computers make us think think things are easy because they calculate them so fast.
Here it is! Feel free to use as you see fit.
