Reform of the date of Easter refers to proposals to change the date for the annual celebration of Easter. These proposals include setting a fixed date or agreeing between Eastern and Western Christendom a common basis for calculating the date of Easter so that all Christians celebrate the Festival on the same day. As of 2024, no such agreement has been reached.
The term may also refer to historic reforms of the Computus, such as the adoption of the epact tables by Dionysius Exiguus in the 6th century and by Bede in the 8th century.
