Here’s the Formula for Finding Out What Date Easter Falls On

Easter Sign

Out of all the major holidays we celebrate throughout the year, Easter is the only holiday that seems to have a floating date. Easter can fall anywhere between March 21st and April 25th and is connected with the spring equinox, full moon, and Sunday. In this blog, we are going to give a bit of history on the date of Easter and how you can figure out what date Easter will fall on in any year.



Easter is actually much older than Christianity itself. The name comes from the Angelo-Saxon goddess of spring Eostre. Easter is a pagan festival to celebrate the spring equinox and rebirth of the earth. That is why bunnies, eggs, and hot cross buns are associated with Easter as they are symbols of spring and renewal from pagan religions.

Full Moon

Ancient pagan religion used a moon-based calendar and held celebrations during the full moon that came after the spring equinox.  In Christianity, in AD 325 the Council of Nicaea agreed that the date of Easter would coincide with the first Sunday after the first full moon after the spring equinox.

Sunday Date

Originally Sunday was the day of the Sabbath, the day of rest. The resurrection of Jesus changed everything in Christianity. Sunday became a forward-looking celebration of new life.

Calculating the Date

Dates of a month

Now that we know a bit of history of the three elements connected to Easter: spring equinox, full moon, and Sunday, we can calculate the date of Easter Sunday. Find what day the spring equinox falls on; e.g., March 19, 2020. Find the first full moon after the spring equinox; e.g., April 8, 2020. Once you know those dates, Easter should fall on the first Sunday after the full moon; e.g., April 12, 2020. Now you have the formula to figure out what date Easter will fall on every year. It is that easy!
