Pascha / Easter Dating
The Church's oldest calendar quarrel: when exactly does Easter fall?
This concerns how the date of Pascha, the feast of Christ's resurrection, is fixed each year. The early Quartodeciman controversy debated whether to keep it on a set day tied to the Jewish reckoning, and the Council of Nicaea in 325 established a common method, or computus, decoupling the feast from that reckoning. The traditions still differ today, as the Western (Gregorian) and most Orthodox (Julian) calculations often place Easter on different dates.
