If you want to print your own calendars, you may need to know when Easter will happen for a given year. Unfortunately, calculating the date of Easter is not easy, since it's related to the phase of the moon. This calculator, based on an algorithm published by Jean Meeus in his excellent book "Astronomical Formulas For Calculators" brilliantly solves the problem. I have no idea on how it works and if you want to know more about it, you definitely should refer to the mentioned book.

This calculator will calculate the date of Easter (Sunday) for the specified year: just type in the year and hit the button. The year must be an integer.

Year: ---

Gregorian calendar (introduced in 1582) and Julian calendar are taken into account. Years are counted astronomically (the year before year 1 is year 0, and the year before is -1). In the Gregorian calendar, Easter has a periodicity of 532 years. Easter is always between March 22 and April 25.
