what determines easter full moon?
[2017 Full Moon Calendar] Put another way, Easter falls on the Sunday that follows the first full moon occurring on or the day after the March equinox. If the full moon occurs on a Sunday, however, then Easter is observed the following Sunday. This year, the fourteenth day of this particular new moon was on April 11 (Eastern Daylight Time), which was a Tuesday. So the following Sunday, April 16, is designated as Easter.
