How The Calculator Works

The calculations are based on a set of rules known as the “Computus”, which has been used since the First Council of Nicaea in AD 325.

The date of Easter is determined based on the cycles of the moon. It falls on the first Sunday following the first ecclesiastical full moon that occurs on or after the vernal equinox.

The vernal equinox is also known as the spring equinox in the Northern Hemisphere. This is one of the two points in the year when the day and night are of approximately equal duration everywhere on Earth.
