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 2027 it falls on December 13, 2027 at 21°25' Gemini. Those names follow the calendar month rather than the zodiac, which is why the 2027 one lands in Gemini at 21°25' Gemini while other years put it elsewhere.
