Easter is a "movable feast" and its date changes every year. In 2024, Easter Sunday will be observed on Sunday, March 31. The exact date of Easter varies each year depending on the Moons position in early spring. Easter always occurs on the first Sunday after the Paschal Full Moon, which is the first full Moon that occurs after the vernal equinox, which signifies the beginning of spring in the northern hemisphere. The earliest Easter can occur in any given year is March 22, and the latest is April 25.
