HOW TO CALCULATE WHEN EASTER WILL FALL.
Easter is always on the first Sunday after the first full moon, on or after the 21st of March. The earliest possible date is the 22nd of March. There are 35 possible dates, but Easter has not fallen on the earliest date since 1818 & will not do so again until 2285. The latest possible date is April 25th, which happened in 1943 & will next fall on that date in 2038. It has been worked out that the cycle of Easter dates repeats after exactly 5,700,000 years, with April 19th being the most common date, occurring 220,400 times. SIMPLE HUH?
