The reason it's called that is because the Native American name for the full moon in December is the cold moon, as it happens when temperatures drop. Most of the ancient full moon names relate to the falling temperatures and darkness of the last month of the year. It is also called the moon before Yule as well as the night moon, deriving that name from the winter solstice, which has the longest night in the year.

According to Earthsky, the nocturnal sun gives us a much appreciated reprieve in the season of diminished daylight. An interesting point to debate over your Christmas dinner is that although some people regard the full moon of December 2019 as the last full moon of the decade. Others believe that the forthcoming one counts as the last full moon in the second decade of the 21st century, if you take it that the next decade runs from 2021 to 2030.

The moon will reach the crest of its full phase on 30 December at 03.28 UTC. For the US, it turns full on 29 December at 10.28pm EST, 9.28pm CST, 8.28pm MST, 7.28pm PST, 6.28pm Alaskan Time and 5.28pm Hawaiian Time.
