Western-Eastern divergence

In Western Christianity, using the Gregorian calendar, Easter always falls on a Sunday between 22 March and 25 April, within about seven days after the astronomical full moon. The preceding Friday, Good Friday, and following Monday, Easter Monday, are legal holidays in many countries with predominantly Christian traditions.

Eastern Orthodox Christians use the same rule but base their 21 March according to the Julian calendar. Because of the thirteen-day difference between the calendars from 1900 through 2099, 21 March Julian corresponds to 3 April in the Gregorian calendar (during the 20th and 21st centuries). Consequently, the date of Orthodox Easter varies between 4 April and 8 May in the Gregorian calendar. Orthodox Easter is usually several days or more than a month later than Western Easter.

Among the Oriental Orthodox, some churches have changed from the Julian to the Gregorian calendar and the date for Easter, as for other fixed and moveable feasts, is the same as in the Western church.

The Greek island of Syros, whose population is divided almost equally between Catholics and Orthodox, is one of the few places where the two Churches share a common date for Easter, with the Catholics accepting the Orthodox date—a practice helping considerably in maintaining good relations between the two communities. Conversely, Orthodox Christians in Finland celebrate Easter according to the Western Christian date.
