changing the date of easter
The Paschal Full Moon can vary as much as two days from the date of the actual full moon, with dates ranging from March 21 to April 18.As a result, Easter dates can range from March 22 through April 25 in Western Christianity.hile some Eastern Orthodox Churches not only maintain the date of Easter based on the Julian Calendar which was in use during the First Ecumenical Council of Nicea in 325 A.D., they also use the actual, astronomical full moon and the actual vernal equinox as observed along the meridian of Jerusalem.
