Why it is called the Cold Moon
The Cold Moon is the traditional North American and European name for the full Moon of December, and in 2031 it falls on December 28, 2031 at 6°46' Cancer. Those names follow the calendar month rather than the zodiac, which is why the 2031 one lands in Cancer at 6°46' Cancer while other years put it elsewhere.
