One thing that sets the Harvest Moon apart from other full Moon names is that it’s not associated with a specific month, as the others are. Instead, the Harvest Moon relates to the timing of the autumnal equinox (September 22 or 23), with the full Moon that occurs nearest to the equinox being the one to take on the name “Harvest Moon.” This means that the Harvest Moon can occur in either September or October, depending on how the lunar cycle lines up with the Gregorian calendar.
