The "Cold Moon" is the traditional name for the December full moon, reflecting the arrival of winter's coldest and darkest nights. The name originated with the Mohawk people but is also known by other names from various Indigenous cultures, such as the "long night moon" or "moon of the popping trees".
This year, the December 2025 Cold Moon is also a supermoon and will rise on the evening of December 4, 2025.
