Reform of the date of Easter has been proposed several times because the current system for determining the date of Easter is seen as presenting two significant problems:

1. Its date varies from year to year (by the Western system of calculation, it can fall on any of 35 dates on the Gregorian calendar). While many Christians do not consider this to be a problem, it can cause frequent difficulties of co-ordination with civil calendars, for example academic terms. Many countries have public holidays around Easter weekend.
2. The Eastern and Western Christian churches calculate Pascha using two different calendars (the Julian and Gregorian, respectively); hence in most years Easter is celebrated on a different date in the East and the West.
