What does Easter celebrate?

Easter is a Christian religious holiday that celebrates and commemorates the resurrection of Jesus Christ. Christians believe, as a central tenet of their faith, that three days after his crucifixion and death, Jesus Christ rose from the dead as proof that he was the son of God.

The Easter season begins seven weeks prior to the holiday in western Christian sects and culminates in the Holy Week prior to Easter. The Easter holiday does not have a fixed date; it is set on the first Sunday after the full moon on or after the March 21. This creates a variance where Easter is celebrated as early as March 22 and as late as April 25.
