Easter is different in Eastern Orthodox Christianity due to the use of the Julian calendar, rather than the Gregorian calendar which is employed by most Western Christian churches. This calendar difference leads to variations in the calculation of Easter's date. Furthermore, Eastern Orthodox churches adhere to the rule set forth by the First Council of Nicaea in AD 325, which requires that Easter must be celebrated on the first Sunday after the first full moon following the vernal equinox, but also after Jewish Passover, ensuring that the dates often do not coincide with those observed by Western Christianity.
