The Harvest Moon is the full moon that happens closest to the autumnal equinox, or the official start of fall. For several nights in a row, a large full moon rises shortly after sunset.
The September equinox (or southward equinox) is the moment when the Sun appears to cross the celestial equator, heading southward. Because of differences between the calendar year and the tropical year, the September equinox may occur from September 21 to 24. At the equinox, the Sun as viewed from the equator rises due east and sets due west.
Qiufen. The traditional Chinese lunisolar calendar divides a year into 24 solar terms. [1] Qiūfēn, Shūbun, Chubun, or Thu phân is the 16th solar term. It begins when the Sun reaches the celestial longitude of 180° and ends when it reaches the longitude of 195°. It more often refers in particular to the day when the Sun is exactly at the ...
Equinox. A solar equinox is a moment in time when the Sun crosses the Earth's equator, which is to say, appears directly above the equator, rather than north or south of the equator. On the day of the equinox, the Sun appears to rise "due east" and set "due west". This occurs twice each year, around 20 March and 23 September.

Historically, it was widely observed throughout Ireland, Scotland, and the Isle of Man. Traditionally, it is held on 1 August, or about halfway between the summer solstice ...
The full moon is the lunar phase when the Moon appears fully illuminated from Earth's perspective. This occurs when Earth is located between the Sun and the Moon (when the ecliptic longitudes of the Sun and Moon differ by 180°). [3] This means that the lunar hemisphere facing Earth—the near side —is completely sunlit and appears as an ...
