Easter calculator. The algorithm is roughly:
Sunday after the first full moon on or after Mar 21. If the full moon is a Sunday, then the following Sunday. The date of the full moon is not an astronomical one and its date is left as an exercise for the reader.
There are two Easters too - the Orthodox one involves the Julian calendar, the Roman (etc) involves the Gregorian calendar.
You could chicken out with a lookup table!
Easter is when you village elder decides it is full moon by looking at it, not your fancy math. Though the math is good enough and really better for a connected world.
