Easter 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 [[Nicean Council]] in 325 AD it was decided that Easter 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 Easter and thus have an inaccurate date for the resurrection. | Easter doesn't fall on a fixed date in the calendar.
