The year’s first Full Moon, (January 6th) Wolf Moon, is named after howling wolves, but it’s also often called the Moon After Yule in the Anglo-Saxon tradition.
The name is thought to have a Celtic and Old English origin, brought over to North America by European settlers. Other Celtic names of the Full Moon include Stay Home Moon and Quiet Moon, while in some Native American cultures, it is called Severe Moon or Center Moon.
In Anglo-Saxon culture, January’s Full Moon was also called the Moon after Yule. Yule is the ancient winter solstice festival usually celebrated around December 21.
