Yet another formula to calculate easter.
The advantage of this one is that it follows the method by C.F.Gauss, published in 1800, that it's very short and does not depend on other custom functions.
It gives accurate dates from 1583 until 4000, beyond 4000 it's incorrect (filemaker doesn't calculate dates beyond 4000 anyway) and before 1583 the julian calandar was used and for that period this formula doesn't work either. For modernday use with the gregorian calander this formula suffices.

I have taken the liberty of using your code in a custom function I have created to work out holidays in Australia.
I have given you credit in this new cf.
