Well, plus one day. According to Wikipedia..
The Harvest Moon is the full moon closest to the autumnal equinox. It is the first full moon closest to that equinox. About once every four years, it occurs in October in the northern hemisphere. Currently, the latest possible Harvest Moon is on October 11.
And something I did not know: “All full moons rise around the time of sunset.”
