Orthodox Easter is decided using the Julian calendar, in contrast to the Gregorian calendar used by many Western Christian churches. The key factor is the Paschal Full Moon; Orthodox Easter falls on the first Sunday after the Paschal Full Moon that occurs on or after the spring equinox. This determination also ensures that Orthodox Easter does not precede or coincide with Jewish Passover, reflecting the historical and theological distinctions unique to Orthodox Christianity.
