Easter is the holiday that celebrates and commemorates the central event of the Christian faith: the resurrection of Jesus Christ three days after his death by crucifixion. All major branches of Christianity observe the holiday. Today, other than church attendance, the holiday often involves Easter Eggs for toys and candy as well as the imagery of bunnies and rabbits (see more below). Easter occurs the Sunday after Good Friday.
The resurrection of Jesus Christ is the centerpiece of the Christian faith, according to the Apostle Paul, who even says that if Jesus Christ has not been resurrected then the Christian faith is worthless and futile (1 Cor. 15:14-17). Therefore, without Easter there is no Christianity.
Easter is the oldest Christian holiday and the most important day of the church year. All the Christian movable feasts and the entire liturgical year of worship are arranged around Easter. Easter is preceded by the season of Lent, a 40-day period of fasting and repentance culminating in Holy Week, and followed by a 50-day Easter Season that stretches from Easter to Pentecost.
