The longest — and last — full moon of the year will appear on Monday night and peak on Tuesday.
December's full moon, also known as the Cold Moon and Long Night Moon, will reach peak illumination at 7:33 p.m. ET on Tuesday, according to NASA. It will look like a full moon until Thursday morning. The Old Farmer's Almanac details specific moonrise times for different ZIP codes across the United States.
To view a full moon, NASA recommends going outside and looking up at the sky. Using a telescope or binoculars will magnify the moon and clarify details on its surface.

Barry Morphew, a longtime suspect in his wife's disappearance and murder, was arrested in Arizona on June 20, 2025, two days after he was indicted on a first-degree murder charge in the case of his wife Suzanne Morphew's death. This was the second time Barry Morphew has been arrested and charged in her death. The initial charges were dismissed without prejudice, meaning authorities reserved the right to charge him again.
