The final full moon of 2023, December’s Cold Full Moon, will rise on Tuesday (Dec. 26) in time to catch the festive season but just missing Christmas Day.
According to In the Sky, the fully-illuminated Cold Moon will rise at around 3:05 p.m. EST (2005 GMT), with the sun setting at 16:33 EST (2133 GMT). The full moon will set at around 8:12 a.m. EST (1312 GMT) the following day after the sun has risen around an hour earlier at 7:16 a.m. EST (1216 GMT), meaning the Cold Moon will be visible for the entire night.
In the build-up to the final full moon of 2023, as the festive season approached, the moon has risen an hour earlier each day, and the portion of the illuminated lunar face has been growing, or “waxing.” Following the Cold Moon and leading up to the first new moon of 2024, which falls on Jan. 11 and marks the first full lunar cycle of 2024, the moon will rise an hour later each day and will be visible for less and less of the night.
As this happens, the illuminated lunar face will recede, a progression that astronomers called “waning.” By the time of the new moon, the lunar face will be completely dark, and the moon will rise at sunrise and set at sunset.

The main name for December’s full moon, the Cold Moon, is attributed to the tradition of the Mohawk people, according to the Farmer’s Almanac. The name refers to the icy conditions of December as the grip of winter tightens around the Northern Hemisphere.
Alternative names for December’s full moon from Native American traditions also reflect the increasingly frigid conditions and the deepening of winter. These include the “Snow Moon” in the Haida and Cherokee traditions and the Western Abenaki people’s moniker for the December full moon, the “Winter Maker Moon.”
Other names for December’s full moon describe how the depths of winter impact flora and fauna. These include the Cree’s wonderfully evocative “Frost Exploding Trees Moon” and the Oglala people’s “Moon of the Popping Trees” name. These nature-based monikers also include the Dakota people’s incredibly descriptive name for the December full moon, the “Moon When the Deer Shed Their Antlers.”
The Mohican name for the December full moon, the “Long Night Moon,” refers to the fact it rises on the nights close to the winter solstice, which are the longest nights of the year. That name is particularly apt this year as December 2023’s full moon will linger over the horizon for longer than most full moons this year due to its proximity to the Winter Solstice — the day of the year with the least sunlight hours, which this year occurred on Thursday, Dec. 21.
The next full moon and the first of the coming year is January’s Wolf Moon, which rises on Jan. 25, 2024.
