The dating of Easter is based on the old Hebrew lunar calendar. It is always the first full moon after the Spring equinox which is March 20^th. Consequently, the earliest Easter can be is March 22^nd , but that is very rare. The last time Easter fell on the 22^nd was in 1818. Easter on March 23^rd is also very rare. You have to be 95 years old or older to have seen another Easter on the 23^rd., and we won’t see one again until 2228. In other words, unless you are planning on living a couple hundred years, none of us will see an Easter as early as this year in our lifetime.
