December's full moon is also known as the Full Cold Moon. According to The Old Farmer's Almanac, certain Native American cultures have dubbed the event the Long Nights Moon, as the winter solstice kicks off around the same time, bringing with it the longest night of the year.
In the Northern Hemisphere, the winter solstice will occur on December 22 at 11:48 a.m. ET.
