Did you Know? (Sunday, May 19, 2019)
Easter is the most important Christian festival of the year, which is a movable event determined by the first Paschal (Full) Moon after March 21, in which the length of day and night are approximately equal everywhere on Earth. This is in keeping with the tradition of the early church, and beginning in 325 AD, at the Council of Nicea, a standardized system for determining the future dates for Easter was established, based on the projection of when the Paschal moon would be.
