As you may or may not be aware, the date of Easter is set based on the lunar calendar. Specifically, Easter (at least in the west, Orthodox Easter is a different date), is the first Sunday after the first full moon after the spring equinox. Since the spring equinox occurs on 20 March, the earliest that Easter can occur is 22 March. The latest Easter can occur is 25 April. This year, Easter falls on 23 March. The last time that it occurred this early was 1913, so there are some people alive who have seen it this early before. The last time it fell on 22 March was 1818 (so no one alive now saw that one). The next time it will fall on 23 March is in 220 years (2228) and the next time it will fall on 22 March is 2285, so I don’t expect to see it. 🙁
