How it is calculated
Western Easter uses the Gregorian computus (Meeus/Jones/Butcher), the first Sunday after the church full moon following 21 March. Orthodox Easter uses the Julian computus, then adds the calendar gap of floor(year ÷ 100) - floor(year ÷ 400) - 2 days. Sham el-Nessim = Orthodox Easter + 1.
Example
Inputs: Year = 2,026. Result: Western Easter: Sunday, April 5, 2026 (2026-04-05); Orthodox Easter (Gregorian date): Sunday, April 12, 2026 (2026-04-12); Good Friday (Western): Friday, April 3, 2026 (2026-04-03).
Limits and caveats
- It starts at 1583 because the Gregorian computus was not in use before then.
- Dates follow the standard church computus; each country sets its own public holiday, which may move to another day.
