According to NASA, December’s full moon is marking the end of the decade in a unique way. It will bright up the sky at 12:12 am Eastern time on the 12th day of the 12th month of the year.
December’s full moon is also known as the “Cold Moon” appearing as the Northern Hemisphere enters its coldest months of the year.
December’s full moon was named Cold Moon by the Algonquin tribes in the northern and eastern United States. Because of the proximity to the winter solstice, the Europeans called the full moon as Long Night Moon.
The moon will be fully visible just after midnight Thursday morning, appearing “opposite” the sun — in Earth-based longitude — at 12:12 a.m. Eastern Standard Time on 12/12.
