Easter dates differ between Eastern and Western Christian churches due to the use of different calendars. Western churches primarily use the Gregorian calendar, while Eastern churches use the Julian calendar. The Julian calendar's inaccuracies cause the date discrepancy. However, in 2025, both will celebrate Easter on the same day. This alignment is a rare occurrence and marks the 1,700th anniversary of the Council of Nicaea.

In 2025, a rare event occurs: Eastern and Western Christian churches will celebrate Easter on the same day, April 20 1. This alignment, coinciding with the 1700th anniversary of the Council of Nicaea, presents a unique opportunity for ecumenical dialogue and a renewed focus on Christian unity 1.
The Council of Nicaea in the fourth century established that Easter should be observed on the first Sunday after the first full moon following the spring equinox 1. However, the Western Church adopted the Gregorian calendar in 1582 to correct inaccuracies in the Julian calendar, which the Eastern Church continues to use for religious observances 1. This difference in calendars results in differing calculations for the spring equinox and full moon, leading to variations in the Easter date 1. Currently, the Julian calendar lags 13 days behind the Gregorian calendar 1.
Both Pope Francis and Orthodox Patriarch Bartholomew of Constantinople have voiced their aspirations that the shared Easter date in 2025 could mark the beginning of greater unity between Eastern and Western Christian traditions 1. Patriarch Bartholomew hopes this alignment will not be a mere coincidence but a catalyst for a unified Easter observance 1. Pope Francis has also reiterated his plea for Christians to seize this opportunity to advance towards unity, viewing the anniversary of the Council of Nicaea as a call to persevere on the path to Christian unity 1. There will be more opportunities for a shared Easter date in 2028, 2031 and 2034 1.
The Catholic Church deeply values Christian unity and ecumenism, viewing it as a central aspect of its mission. This commitment is rooted in the belief that Jesus Christ founded one Church, and the division among Christians wounds Christ's will. The Second Vatican Council's Decree on Ecumenism, Unitatis Redintegratio, articulates the principles and goals of the Church's ecumenical movement. The Church engages in dialogue and collaboration with other Christian communities to overcome historical divisions and work towards full communion.
