If the full moon is on a Sunday, Easter is the Sunday after.
This is because it would otherwise coincide with the Jewish Passover.
Celebrates Christ's resurrection.
According to Bede (d.735), the name is derived from Eostre, the old Teutonic
goddess of the spring.
Also is an adaptation of Passover.

Easter may occur on any Sunday between March 22 and April 25, inclusive.
We say that it is on the first Sunday after the first full moon following the spring equinox,
but calculating the moon phases and equinox can be difficult, especially for Medeival priests.
Therefore, for purposes of calculating Easter, the spring equinox is always considered
to be on March 21, and the epact is used for determining the moon phases.
Because Easter is always on a Sunday, the dominical letter is also part of the equation.
For leap years use the second letter.
Use the epact and dominical letter for any year to look up the date of Easter in the table.
To determine the date of Orthodox Easter, use this trick: reset epact to (epact+9)%30,
and use the next dominical letter (so that A becomes B, and G becomes A).
This will get the date on the Julian calendar.
For the corresponding date on the Gregorian calendar, add 13 days.
