Paschal Full Moon
From Wikipedia, the free encyclopedia
The Paschal Full Moon roughly corresponds to the first full moon of Spring. The name Paschal stems from the fact that each year, the date of Easter is chosen to be the first Sunday after the Paschal Full Moon.
Historically, the Paschal Full Moon was the first full moon which occurs on or after the day of the vernal equinox. Later, the Paschal Full Moon referred to the day which was thirteen days after the Ecclesiastical new moon, and does not have any direct correspondence to an actual full moon. The calculations to determine the date of the Paschal Full Moon (and Easter) are somewhat complex. For a detailed discussion, Computus.
