Thank you, Gary. First, find the spring equinox for the planet on our side of the hemisphere. It might take an almanac. But, since most people do not have an almanac readily handy, we've provided the spring equinox timetable for the next 211 years. Now we must look up the moon phases for the month, to find the first full moon following the spring equinox.
Some calendars come with the moon phases.
The moon phases help to calculate the date of Easter. Since most people wouldn't have a clue as to where to find moon phase data, we have found the phrases of the moon for you here . When we find the first full moon, simply run your finger to the first Sunday that follows it. That will be Easter Sunday . Easter Sunday is the date of the annual celebration of Christ's resurrection.
