The origin of the English word Easter parallel to the German word Ostern is uncertain. It is likely derived from Christian names for Easter week, such as albis, a Latin phrase understood as the plural of alba ("dawn"), which became eostarum in Old High German. The Latin and Greek Pascha ("Passover") provide the root for Pâques, the French word for Easter.

Easter is one of Christianity's most important holidays or feasts. It commemorates Jesus' resurrection three days after his crucifixion. Easter marks the end of the Lenten season of fasting and penitence for many Christian denominations. Though it is possible that even the first Christians observed the Resurrection, which is a fundamental component of the faith, the first recorded celebration of Easter dates from the 2nd century.
