What is the history of Easter?

Easter commemorates the resurrection of Jesus Christ, three days after he was crucified by Romans around 30 A.D.

“Easter’s roots (date back to) a day in the week in which Christ rose from the dead. It would have been the first day of the week after the Jewish Sabbath, which was Saturday,” Timothy P. O’Malley, a faculty member at the University of Notre Dame’s McGrath Institute for Church Life, told USA TODAY.

“Early Christians celebrated, therefore, every Sunday like it was Easter. There was no annual commemoration of Easter early on, but by the second and third centuries, there comes to be an annual celebration of Easter,” O’Malley continued, adding that the celebration later grew.
