More about holy days

Find Holy Days

You can use this page to generate a list of the holy days in the year you specify. If you are wondering when Easter Day falls in a given year, this is how to find out.

Western Holy Days
Best for the years 1900 to 2099, inclusive.
Eastern Holy Days
Valid after 325, also finds Easter for all locations before 1583 and in English-speaking countries before 1753.

You can go to another page to read about the three calendars that are in use in Christendom:

You can also make and print a wall-style calendar.

Western Holy Days

The Western Church includes the Roman Catholic Church, the Anglican Communion, and all Protestant bodies.

You can generate a calendar that is valid for the Western Church, which uses the Gregorian Calendar. The first full Gregorian year was 1583. You can generate a calendar for any year from 1583 to 9999.

If you enter a year earlier than 1583, you’ll get the holy days for 1583.
If you enter no year at all, you’ll get the holy days for the current year.

The latest year for which you can generate a calendar is 9999. If your plans require you to know the date of Easter any later than that, I would be very interested in learning the details of your diet, medications, and exercise regimen.

My method of determining the western date of Easter may produce errors before 1875. Some regions retained their own methods of calculating Easter.

Eastern Holy Days

The Eastern Church includes the Eastern Orthodox churches, the Oriental Orthodox churches, and the eastern-rite churches that are affiliated with the Roman Catholic Church.

You can generate a calendar that is valid for most Orthodox Churches, which still use the Julian Calendar. The current method of calculating Easter was first instituted by the Council of Nicea in AD 325.

If you enter a year earlier than 325, you’ll get the holy days for 325.
If you enter no year at all, you’ll get the holy days for the current year.

You can also use this to estimate the date of Easter Day in any year before 1583, or in English-speaking countries before 1753.

This program is as accurate as I can make it; however, I offer no warranty for accuracy. The results may not be accurate for years before 1875, in part because some regions retained their own methods of calculating Easter.
