About the Easter Date Calculator
Easter is a moving feast. It is not on a fixed date, but on the first Sunday after the first full moon on or after 21 March. The rules to find the exact date, called the computus, are fiddly, but a computer can do them in an instant. This calculator gives the date of Easter Sunday for a year of your choice by the Western (Gregorian) or the Orthodox (Julian) reckoning, and the related feast days that depend on it. Type the year and the church calendar and the Easter date appears at once, with a few related figures underneath, and you can copy the result with one tap. The sums run in your browser, so nothing you enter is uploaded.

When you need the Easter date
Schools, businesses and churches plan holidays around Easter. Travel agents and planners need the date years ahead, and calendar makers use it to print the right holidays. Western Easter always falls between 22 March and 25 April.
The two dates sometimes match and sometimes differ by one, four or five weeks. The Orthodox date uses an older calendar and an older method of finding the full moon, so it is later or equal.
How the Easter date is worked out
The Western date uses the Meeus–Jones–Butcher algorithm for the Gregorian calendar. The Orthodox date uses the Julian computus and then adds the difference between the two calendars (13 days in the 20th and 21st centuries). Western Easter in 2026 is Sunday 5 April, and Orthodox Easter is 12 April. In 2025 both fall on 20 April. In 2024 the Western date is 31 March and the Orthodox date 5 May. Ash Wednesday in 2026 is 18 February, Good Friday 3 April, Ascension Day 14 May and Pentecost 24 May.
Every answer on this page comes from that one rule, so you can check any result by hand with a calculator. The figures shown underneath, such as other units, are conversions of the same answer.

The dates are for the Sunday itself. Related days are counted back or forward from it: Ash Wednesday is 46 days before, Good Friday 2 days before, Ascension 39 days after and Pentecost 49 days after. The tool covers years 1583 to 4099, as the Gregorian calendar began in 1582.
On phone and computer
On a phone, type into the boxes one after another and read the Easter date underneath; Copy result puts it on the clipboard for a message or a note. On a computer the inputs sit on the left and the answer on the right, so you can change one figure and watch the Easter date move. The easter date calculator works the same on both. Plan the holiday with Day of the Year Calculator, Days Between Dates, Working Days Calculator and Calendar Maker for printed dates.
