The Catholic Church and the Orthodox Church have historically celebrated Easter on different dates. This is due to the different calendar systems they follow: the Gregorian calendar, used by the Catholic Church, and the Julian calendar, used by the Orthodox Church. The two calendar systems cause the vernal equinox to fall on different dates, resulting in different calculations for Easter. While the Catholic Church no longer observes the tradition of celebrating Easter after Passover, the Orthodox Church continues to do so, further contributing to the date difference. In rare instances, such as in 2017 and 2025, the dates for Easter align, and both churches celebrate the holiday simultaneously.

What You'll Learn
The Julian calendar vs. the Gregorian calendar
The Julian calendar was introduced by Julius Caesar in 45 B.C. and was used to account for the movements of the sun and the moon. However, it was less accurate than its successor, the Gregorian calendar, especially in its calculation of leap years. The Gregorian calendar, introduced by Pope Gregory XIII in 1582, is a more accurate solar calendar. It successfully connects months to the length of a year, which is about a quarter of a day longer than 365 days.
The Catholic Church uses the Gregorian calendar, whereas the Orthodox Church uses the Julian calendar for liturgical purposes. This is because the Orthodox Church still follows the original Nicean Council's formula for Easter, which states that Easter should be celebrated on the first Sunday after the first full moon following the vernal equinox. The Nicean Council believed they had finalized a universal date for Easter, but the Great Schism of 1054 divided the church into the Catholic and Orthodox churches, which chose their own methods and calculations.
The two churches now celebrate Easter on different dates, with the Orthodox Easter falling anywhere between April 4 and May 8, and the Catholic Easter falling between March 22 and April 25. However, in rare instances, the dates align, and Easter is celebrated simultaneously. For example, in 2017, both the Orthodox and Catholic Easters fell on the same day, and in 2025, they will again coincide on April 20. This coincidence has been seen as an opportunity for Christian unity, with Pope Francis expressing his belief that Catholics and Orthodox Christians will one day attain full communion.

The date of Easter
On the other hand, the Orthodox Church follows the original Nicean Council's formula for Easter and adheres to the Julian calendar, introduced by Julius Caesar in 45 B.C. The Julian calendar is less accurate, especially in its calculation of leap years. The Orthodox calculation of Easter is based on the first Sunday after the first full moon that falls after (or on) the vernal equinox, but with different dates for the vernal equinox and the full moon. This results in the Eastern Orthodox Easter often falling later than Western Easter, although there are rare instances when the dates align.
The difference in the calculation methods for Easter dates back to the Great Schism of 1054, which divided the church into the Catholic and Orthodox churches. The Eastern and Western halves of the church chose their own emperors and heads of the church, and while they shared some doctrinal views, they also had key differences. The date of Easter is one of the issues that continue to set the two churches apart.
In recent years, there have been calls for a common date for Easter, with Pope Francis expressing his belief that Catholics and Orthodox will attain full communion. In 2025, a remarkable coincidence will occur, with both the Eastern and Western churches celebrating Easter on the same day—April 20. This joint celebration has been hailed as an opportunity for Christian unity, and it remains to be seen whether it will lead to a more permanent alignment of Easter dates between the two traditions.

The calculation of Easter
The formula for calculating Easter Sunday is generally agreed upon by both the Orthodox and Catholic churches. According to the Council of Nicaea in 325, Easter should be observed on the first Sunday following the first full moon after the vernal equinox. However, the interpretation of this formula varies between the two churches. The Orthodox Church calculates the vernal equinox and the full moon using the Julian calendar, while the Catholic Church employs the Gregorian calendar for its calculations.
The Julian calendar, introduced by Julius Caesar in 45 BCE, is less accurate than the Gregorian calendar in calculating leap years. As a result, the Eastern Orthodox Church's Easter often falls later than Western Easter. However, there are rare instances when the two dates coincide, such as in 2010, 2011, 2014, and 2017. These coincidences occur when the full moon following the equinox is late enough to be considered the first full moon after March 21 in both the Julian and Gregorian calendars.
The use of different calendar systems is not the only factor influencing the calculation of Easter. The Orthodox Church maintains the traditional belief that Easter must take place after the Jewish Passover to maintain the biblical sequence of Christ's Passion. In contrast, the Catholic Church and most of Western Christianity have abandoned this requirement, resulting in instances where Western Easter falls before or during the Jewish Passover.
Despite the differences in calculation methods, there have been efforts towards unifying the date of Easter. Pope Francis and Ecumenical Patriarch Bartholomew of Constantinople have expressed their desire for Christians to unite around a common date for Easter. In 2025, a remarkable coincidence will occur when both Eastern and Western churches celebrate Easter on the same day, April 20, providing an opportunity to strengthen Christian unity.

The Jewish celebration of Passover
Passover begins on the 15th day of the month of Nisan in the Jewish calendar, which typically falls in March or April in the Gregorian calendar, and lasts for seven or eight days. During this time, all leavened products are prohibited, and the only grain product that can be eaten is unleavened bread, called matzo. The matzo symbolises both the Hebrews' suffering in bondage and their hurried departure from Egypt.
The seder is a central part of the Passover celebration and involves a ritual meal and immersive learning experience guided by the Haggadah, a text that retells the Exodus story. The seder plate displays symbolic food items such as bitter herbs to remind participants of the sting of slavery, green vegetables to symbolise springtime renewal, and four cups of wine to represent the sweetness and joy of freedom. The seder is also an opportunity for intergenerational teaching, as children learn about the significance of Passover and are encouraged to reflect on their own personal journeys towards freedom.
Another important aspect of Passover is the recitation of Hallel, a collection of Psalms praising and thanking God. On the initial day or days of Passover, the entirety of Hallel is recited, while only half is recited on subsequent days. This traditional practice is widely observed by adherents of the Jewish faith as an expression of gratitude and celebration.
Outside of Israel, in the Jewish diaspora, the seventh day of Passover, known as Shvi'i shel Pesach, is celebrated on both the seventh and eighth days. This day commemorates the miraculous "Splitting of the Sea" or Passage of the Red Sea, where the Children of Israel escaped their Egyptian pursuers.

Christian worship and unity
The Christian Church has a long history of celebrating Easter on different dates, with the Catholic Church and the Orthodox Church being no exception. This difference in Easter dates is due to the various methods employed in calculating the Easter celebration. While both the Orthodox and Catholic Churches use the same formula, they input different data into it. The formula is that Easter is to be celebrated on the first Sunday after the first full moon that falls after (or on) the vernal equinox. However, the Catholic Church uses the Gregorian calendar, while the Orthodox Church uses the Julian calendar for liturgical purposes. The Julian calendar is less accurate than the Gregorian calendar, especially in its calculation of leap years. This discrepancy in calendars results in the Catholic and Orthodox Churches celebrating Easter on different dates, with the Orthodox Easter often falling later than the Catholic Easter.
Despite these differences, there have been instances where the Catholic and Orthodox Easters have coincided. For example, in 2010, 2011, 2014, and 2017, both denominations celebrated Easter on the same day. This coincidence will occur again in 2025, with all Christians, East and West, celebrating Easter on Sunday, April 20. This rare occurrence has sparked conversations about Christian unity and the potential for a common Easter date. Pope Francis has expressed his desire for Catholics and Orthodox Christians to attain full communion and has suggested that a shared Easter date could be a step towards unity. Ecumenical Patriarch Bartholomew of Constantinople, a key figure in the Eastern Orthodox Church, has also acknowledged the significance of this alignment, urging Francis to accept the Julian calendar for the Catholic celebration of Easter.
The idea of a common Easter date is not a new concept. In fact, the Council of Nicaea in 325 aimed to establish a universal date for Easter. However, the Great Schism of 1054 divided the church into the Catholic and Orthodox denominations, and they began to follow different calendars. While the Catholic Church uses the Gregorian calendar, the Orthodox Church adheres to the Julian calendar and the original Nicean Council's formula for Easter. This divergence in calendars has resulted in the ongoing difference in Easter dates between the two denominations.
Despite the differences in calendars and Easter dates, both the Catholic and Orthodox Churches share fundamental similarities in their worship and unity. They both accept the first seven Ecumenical Councils of the Church, recognize the seven sacraments, and uphold apostolic succession. Additionally, the Catholic Church, as a papal monarchy, has the advantage of acting from a single center, while the Orthodox Churches demonstrate remarkable coherence in liturgy and the doctrine of faith, even with their local and national jurisdictions. This coherence within the Orthodox Churches showcases a strong sense of unity despite their decentralized power structure.
While the date of Easter has symbolic importance, it is not the primary issue that divides the Catholic and Orthodox Churches. The primacy of the pope is a key area of difference, with the Eastern Orthodox Church gradually separating from Rome in the Middle Ages due to various doctrinal views. However, both denominations share a deep desire for unity, and the rare occurrence of a shared Easter date in 2025 presents an opportunity to strengthen their bond. As Ecumenical Patriarch Bartholomew stated, this alignment is "a great opportunity for togetherness," and it is hoped that it will foster a deeper sense of unity among Christians worldwide.
