Easter is not fixed to a civil date. The Council of Nicaea in 325 tied it to the first Sunday after the paschal full moon, the ecclesiastical full moon used after the northern spring equinox. Western churches now compute that rule on the Gregorian calendar, so the equinox is fixed to March 21 in the modern civil calendar. Most Orthodox churches still use the Julian calendar for the paschal calculation, then publish the result as a Gregorian date. The Julian calendar is currently 13 days behind the Gregorian calendar for March and April dates in 1900-2099, and that offset becomes 14 days in 2100.
The two systems also use different lunar tables, so the paschal full moon can land in different weeks. When the computed full moon and Sunday line up, both churches share Easter; this happens 57 times between 1900 and 2100. In many other years Orthodox Easter is one, four, or five weeks after Western Easter, and the largest deviations come from the Julian equinox and the rule that Orthodox Easter must follow the Julian paschal full moon. This calculator uses the standard Gauss/Meeus computus formulas rather than astronomical moon observations, matching the ecclesiastical calendars.
