Orthodox and Western churches don’t celebrate Easter together.
Orthodox Christians celebrate Easter on April 12th. This date is later than the Easter celebrations of Western churches. The difference is because of the calendars used by the churches.
The Orthodox Church uses the Julian calendar. This calendar is older than the Gregorian calendar. Most other Christian churches use the Gregorian calendar. Because of this difference, Easter is celebrated on a different date. This difference will continue until 2026. Then, Easter will be the same date for many churches.
