Since the early Middle Ages, all Christians have used the same method for determining the date of Easter, though they arrive at a different result. Described authoritatively in The Reckoning of Time by eighth-century English scholar Bede, “The Sunday following the full moon which falls on or after the equinox will give the lawful Easter.” The equinox is observed on March 21. This straightforward method based upon an easily observable natural phenomenon survived the Schism of 1054, when the Catholic and Orthodox Churches split from each other.
