The "harvest moon" and the "hunter's moon" are traditional names for the full moons in late summer and in the autumn in the [[Northern Hemisphere]], usually in September and October, respectively.<ref>{{Cite web |date=2024-01-10 |title=What Makes the Hunter's Moon Special? {{!}} Almanac.com |url=https://www.almanac.com/what-makes-hunters-moon-special |access-date=2024-06-23 |website=www.almanac.com |language=en}}</ref> People may celebrate these occurrences in festivities such as the Chinese [[Mid-Autumn Festival]].

The "harvest moon" (also known as the "barley moon" or "full corn moon") is the full moon nearest to the [[September equinox|autumnal equinox]] (22 or 23 September), occurring anytime within two weeks before or after that date.<ref>{{cite web |url= http://www.almanac.com/content/what-harvest-moon |title= What is a Harvest Moon? |publisher= [[Old Farmer's Almanac]] |access-date= 2017-05-10 |archive-date= 2017-05-11 |archive-url= https://web.archive.org/web/20170511071841/http://www.almanac.com/content/what-harvest-moon |url-status= live }}</ref> The "hunter's moon" is the full moon following it.

All full moons rise around the time of sunset. Since the Moon moves eastward among the stars faster than the Sun, lunar [[culmination]] is delayed by about 50.47 minutes<ref>1440 minutes / 29.531 days = 50.47 minutes</ref> (on average) each day, thus causing moonrise to occur later each day.

Due to the high [[lunar standstill]], the harvest and hunter's moons of 2007 were special because the time difference between moonrises on successive evenings was much shorter than average. The moon rose about 30 minutes later from one night to the next, as seen from about 40° N or S latitude (because the full moon of September 2007 rose in the northeast rather than in the east). Hence, no long period of darkness occurred between sunset and moonrise for several days after the full moon,<ref>{{cite web |url= http://calgary.rasc.ca/sunset_moonrise.htm |title= Sunset and Moonrise |first= Larry |last= McNish |publisher= RASC Calgary Centre |year= 2007 |quote= This gives a graph showing the effect as seen from Calgary, for the whole of the year 2007. |access-date= 2016-02-19 |archive-date= 2017-03-17 |archive-url= https://web.archive.org/web/20170317232428/http://calgary.rasc.ca/sunset_moonrise.htm |url-status= live }}</ref> thus lengthening the time in the evening when there is enough twilight and [[moonlight]] to work to get the harvest in.
