Easter, also called Pascha or Resurrection Sunday, is a Christian festival and cultural holiday commemorating the resurrection of Jesus from the dead, described in the New Testament as having occurred on the third day of his burial following his crucifixion by the Romans at Calvary c. 30 AD. It is the culmination of the Passion of Jesus Christ, preceded by Lent, a 40-day period of fasting, prayer, and penance.

The Revised Julian calendar, or less formally the new calendar, is a calendar proposed in 1923 by the Serbian scientist Milutin Milanković as a more accurate alternative to both Julian and Gregorian calendars. At the time, the Julian calendar was still in use by all of the Eastern Orthodox Churches and affiliated nations, while the Catholic and Protestant nations were using the Gregorian calendar. Thus, Milanković's aim was to discontinue the divergence between the naming of dates in Eastern and Western churches and nations. It was intended to replace the Julian calendar in Eastern Orthodox Churches and nations. From 1 March 1600 through 28 February 2800, the Revised Julian calendar aligns its dates with the Gregorian calendar, which had been proclaimed in 1582 by Pope Gregory XIII.
Great Lent, or the Great Fast, is the most important fasting season of the church year within many denominations of Eastern Christianity. It is intended to prepare Christians for the greatest feast of the church year, Pascha (Easter).

In the Eastern Orthodox Church, the feast of the Resurrection of Jesus, called Pascha (Easter), is the greatest of all holy days and as such it is called the "feast of feasts". Immediately below it in importance, there is a group of Twelve Great Feasts. Together with Pascha, these are the most significant dates on the Orthodox liturgical calendar. Eight of the great feasts are in honor of Jesus Christ, while the other four are dedicated to the Virgin Mary — the Theotokos.
The Paschal cycle, in Eastern Orthodox Christianity, is the cycle of the moveable feasts built around Pascha (Easter). The cycle consists of approximately ten weeks before and seven weeks after Pascha. The ten weeks before Pascha are known as the period of the Triodion, referring to the liturgical book that contains the services for this liturgical season. This period includes the three weeks preceding Great Lent, the "pre-Lenten period", the forty days of Lent, and Holy Week. The 50 days following Pascha are called the Pentecostarion, also named after the liturgical book.

In Christianity, the Nativity Fast—or Fast of the Prophets in Ethiopian Orthodox Tewahedo Church and Eritrean Orthodox Tewahedo Church—is a period of abstinence and penance practiced by the Eastern Orthodox Church, Oriental Orthodox Church and Catholic Church in preparation for the Nativity of Jesus on December 25. Ethiopian and Eritrean Orthodox Churches commence the season on November 24th and end the season on the day of Ethiopian Christmas which falls on 7th of January.

The Eastern fast runs for 40 days instead of four or six weeks and thematically focuses on proclamation and glorification of the Incarnation of God, whereas the Western Advent focuses on three comings of Jesus Christ: his birth, reception of his grace by the faithful, and his Second Coming or Parousia.
