This function returns incorrect results for all years before 1583.

Maybe the description for this function should be: Calculates the date of Easter sunday in the Gregorian calendar.

Hi, I have a problem with this formula, as the output date is not recognized equal to a the field "DateofMonth". I mean:
DateofMonth (08/04/2012) is not recognized equal to EasterDate (08/04/2012) this one calculated with your formula. This I need to mark on a calendar form the holiday date. How it is possible?
