Religious festivals are commonly celebrated on recurring cycles in a calendar year or lunar calendar. The central festival of Christianity is Easter, on which Christians celebrate their belief that Jesus Christ rose from the dead on the third day after his crucifixion. Even for Easter, however, there is no agreement among the various Christian traditions regarding the date or manner of the observance, less for Christmas, Pentecost, or various other holidays. Both Protestants and Catholics observe certain festivals commemorating events in the life of Christ. Of these, the two most important are Christmas, which commemorates the Birth of Jesus, and Easter, which marks his resurrection. Hindu 'Utsava' is the Sanskrit word for Hindu festivals, meaning 'to cause to grow 'upward'.[citation needed] Hindus observe sacred occasions by festive observances. All festivals in Hinduism are predominantly religious in character and significance. Many festivals are seasonal. Some celebrate harvest and the birth of gods or heroes. Some are dedicated to important events in Hindu mythology.
