In the Western World Easter falls on the first Sunday after the first full moon that occurs on or immediately after March 21st. If the full moon occurs on Sunday, then Easter occurs on the following Sunday. The March 21st date, refers to the vernal equinox, although the vernal equinox does not always coincide exactly with March 21st, this date has traditionally been used in determining the Easter date.
The evolution of this formula used to determine Easter goes back to the beginnings of Christianity which would make for a very interesting article in itself, but after-all, the headline reads Easter Weather In Nashville.
