For the first time in nearly 100 years Easter is coming at its earliest on Sunday, March 23, 2008. The last time Easter Sunday fell on March 23 was in 1913. However, Easter can occur earlier than March 23. The earliest Easter ever recorded in the Gregorian calendar from 1753 onwards was on March 22, both in 1761 and 1818. The next time Easter occurs on March 23 will not be until 2160, and a March 22 Easter will not happen until the year 2285. The Easter date is set around the time of the vernal, or spring, equinox, when the length of day and night is nearly equal in every part of the world.
