Protestants calculate Easter using the Gregorian calendar. Easter falls on the first Sunday after the first full moon occurring on or after the vernal equinox. The vernal equinox is fixed on March 21, meaning Easter can occur on any Sunday between March 22 and April 25. This method was established by the Council of Nicaea in 325 AD and is shared by both Protestant and Roman Catholic traditions. However, Eastern Orthodox Churches calculate Easter differently, using the Julian calendar.
