When Is Easter Celebrated?

Easter’s date changes annually according to a system established by the Council of Nicaea (AD 325) to reflect both solar and lunar calendars.

1. Calculation Rules

  • Vernal Equinox Fixed Date: March 21 (ecclesiastical, not astronomical).
  • Paschal Full Moon: The first ecclesiastical full moon on or after March 21.
  • Easter Sunday: The Sunday following that Paschal Full Moon.

2. Range of Dates

Because of this formula, Easter can fall as early as March 22 and as late as April 25 in Western churches.

3. Liturgical Calendar Placement

Western (Gregorian) Easter differs from Eastern (Julian) calendars, so Orthodox Easter often occurs one to five weeks later. In 2025, Western Easter is April 20; Eastern (Orthodox) Easter is May 4.

4. Preceding Seasons

  • Ash Wednesday: Begins Lent—40 days (excluding Sundays) before Easter.
  • Holy Week: Palm Sunday, Maundy Thursday, Good Friday, Holy Saturday lead into Easter Sunday.
