When Is Easter Celebrated In 2025. Easter is commonly celebrated on the first sunday following the first full moon after the vernal. Easter also called resurrection sunday or pascha is one of the most important days in the christian faith.

This date is significant for many reasons, not least of which is that it falls on the first sunday following the full moon. We determine when easter is by calculating the first sunday after the paschal full moon, which is the first full moon appearing after the vernal equinox (which happens on april 13).
