Generally, the first Full Moon of a Northern Hemisphere spring precedes the imminent arrival of Easter.
Easter Sunday usually lands on the first Sunday after the first Full Moon in spring, leading some to expect Easter Sunday to take place on March 24.
However, by ecclesiastical rules, the equinox is actually fixed on March 21, so that places this year’s Easter Sunday on April 21.
The last time that an ecclesiastical and an astronomical Easter didn’t occur on the same date was 38 years ago, in 1981.
