Resurrection Sunday doesn't fall on a fixed date in the calendar. Instead, it is based on a lunar calendar like that used by the Jews. At the [[Nicaean Council]] in 325 AD it was decided that Resurrection Sunday would be celebrated on the Sunday after the first full moon on or after the day of the vernal equinox. The date of the [[full moon]] was to be determined by using the [[Metonic Cycle]]. Eastern Orthodox Churches still use the Julian calendar when determining the date of Resurrection Sunday and thus have a different date for the celebration. | Resurrection Sunday doesn't fall on a fixed date in the calendar.
