Enter a year, and the tool calculates the exact date of Easter Sunday for that year using the Computus algorithm.
Easter is the first Sunday after the first ecclesiastical full moon on or after March 21. This tool uses the Anonymous Gregorian Computus algorithm to compute it exactly.
In the Gregorian calendar, Easter Sunday can fall anywhere from March 22 to April 25.
Not always. This calculates Western (Gregorian) Easter. Orthodox churches use the Julian calendar, so their Easter often falls on a different date.
