What is Orthodox Easter?

His resurrection forms the basis of Christian faith as it demonstrates Jesus to be the Son of God, and symbolizes his conquest of death.

In most years its date differs from the date of Easter in Western Christianity (catholic and protestant Easter), and is usually one week, but occasionally four or five weeks, later. However, in some years Orthodox Easter coincides with Western Easter and both observances fall on the same date.

In Western Christianity, the date of Easter is based on the Gregorian calendar and can fall between March 22 and April 25. The Eastern Christian tradition bases its calculations of Orthodox Easter on the Julian calendar, which differs from the Gregorian calendar by 13 days. This results in a possible date range of April 4 to May 8. However, both Western and Eastern churches agree that Easter should be celebrated on the first Sunday after the first full moon after the Spring Equinox, but always after Passover.
