Last Full Moon of 2020 is coming Dec 29th in the US.
BUNDLE UP FOR DECEMBER'S FULL COLD MOON!
Other names that allude to the cold and snow include Drift Clearing Moon (Cree), Frost Exploding Trees Moon (Cree), Moon of the Popping Trees (Oglala), Hoar Frost Moon (Cree), Snow Moon (Haida, Cherokee), and Winter Maker Moon (Western Abenaki).
This full Moon has also been called the Long Night Moon (Mohican), as it rose during the “longest” nights of the year, which are near the December winter solstice. This name is also fitting because December’s full Moon shines above the horizon for a longer period of time than most full Moons.
In Europe, ancient pagans called the December full Moon the “Moon Before Yule,” in honor of the Yuletide festival celebrating the return of the sun heralded by winter solstice.
