The Paschal Full Moon is the first full moon that occurs on or after the vernal equinox, which is around March 21 each year. This date is significant in the Christian calendar as it helps determine the date of Easter, which is celebrated on the first Sunday following the Paschal Full Moon. The Paschal Full Moon is important for various Christian traditions, as it symbolizes renewal and rebirth. The Church uses this lunar event to maintain a connection with the Jewish calendar, which is also based on lunar cycles, particularly for the celebration of Passover.
