EASTER

Easter is termed a moveable feast because it is not fixed in relation to the civil calendar. Easter falls at some point between late March and late April each year (early April to early May in Eastern Christianity), following the cycle of the moon. After several centuries of disagreement, all churches accepted the computation of the Alexandrian Church (now the Coptic Church) that Easter is the first Sunday after the first fourteenth day of the moon (the Paschal Full Moon) that is on or after the ecclesiastical vernal equinox.

 Eastern Christianity

In Eastern Christianity, preparations begin with Great Lent, which lasts for 40 days. Following the fifth Sunday of Great Lent is Palm Week, which ends with Lazarus Saturday. Lazarus Saturday officially brings Great Lent to a close, although the fast continues for the following week. After Lazarus Saturday comes Palm Sunday, Holy Week, and finally Easter itself, or Pascha (Πάσχα), and the fast is broken immediately after the Divine Liturgy. Easter is immediately followed by Bright Week, during which there is no fasting, even on Wednesday and Friday.

The Paschal Service consists of Paschal Matins, Hours, and Liturgy, which traditionally begins at midnight of Pascha morning. Placing the Paschal Divine Liturgy at midnight guarantees that no Divine Liturgy will come earlier in the morning, ensuring its place as the pre-eminent "Feast of Feasts" in the liturgical year.
