There are two Easter Sundays due to the different calendars used by the Western (Gregorian) and Eastern (Julian) Christian churches. The date calculation for Easter is complex, hinging on the vernal equinox and the phases of the moon. As a result, the Western church's Easter can vary from March 22 to April 25, while the Eastern church celebrates between April 4 and May 8. This discrepancy leads to the observation of Easter on two different Sundays.
