Busy Beavers in the Moonlight
According to some sources, the Full Moon for November is named after beavers because, at this time, they become particularly active in building their winter dams in preparation for the cold season. The beaver is mainly nocturnal, so they work under the light of the Full Moon.
Native American names for the November Full Moon are Frost Moon, Freezing Moon, Trading Moon, and Snow Moon, although the latter is more common for the February Full Moon. Oak Moon can be either the Full Moon in November or December, depending on which source you use.
In Celtic tradition, the last Full Moon before the December solstice has also been named the Mourning Moon or the Darkest Depths Moon.
The astronomical seasons do not match up with the lunar months. Therefore, the month of the Mourning Moon in the Northern Hemisphere varies. In some years, the Mourning Moon is in November, while in others, it is in December.
