Easter Calculator — Date of Easter Sunday
Enter any year to instantly find the date of Easter Sunday — the result uses the standard Meeus/Jones/Butcher algorithm for the Gregorian calendar.
Kako radi ovaj kalkulator?
Easter Sunday is the first Sunday after the first ecclesiastical full moon on or after 21 March. This calculator uses the Meeus/Jones/Butcher algorithm, which is exact for the Gregorian calendar (1583 onward). The date always falls between 22 March and 25 April.
Formula
How this is calculated
Easter Sunday is defined as the first Sunday after the first full moon on or after the spring equinox (March 21). Because this depends on an ecclesiastical approximation of the lunar cycle rather than the actual astronomical moon, the date is computed algorithmically rather than looked up from a lunar table.
This calculator uses the Meeus/Jones/Butcher algorithm, the standard method for Gregorian Easter dates. It is valid for all years from 1583 (when the Gregorian calendar was introduced) onward, producing dates between 22 March (the earliest possible Easter) and 25 April (the latest possible Easter). The algorithm uses only integer arithmetic and modular division — no astronomical observation is required.
Note that Eastern Orthodox Easter uses the Julian calendar and the Julian version of the algorithm, so it typically falls 1–5 weeks later than Western (Gregorian) Easter. This calculator computes only the Gregorian (Western) date. The result always falls on a Sunday by construction.
Često postavljana pitanja
Easter is a "moveable feast" tied to the lunar calendar: it is the first Sunday after the first ecclesiastical full moon on or after 21 March (the fixed spring equinox in the church calendar). Because lunations (≈29.5 days) do not align with the solar year, the date shifts each year within a 35-day window from 22 March to 25 April.
Yes. Western (Catholic and Protestant) churches use the Gregorian calendar; Eastern Orthodox churches use the Julian calendar, which currently runs 13 days behind. Both use the "first Sunday after the first full moon after March 21" rule, but on different calendar systems, so the dates often differ by 1–5 weeks. This calculator computes only the Gregorian date.
On the Gregorian calendar, Easter can fall as early as 22 March (the last time was 1818; the next is 2285) and as late as 25 April (most recently 1943; next in 2038). The most common Easter dates cluster around early-to-mid April.
