The Christmas Moon 2015

There will be a full moon this Christmas for the first time since 1977. It will rise at 4:04 PM on Christmas Eve, reach the crest of its full phase (residing exactly 180 degrees from the sun in ecliptic longitude) at 3:11 AM on Christmas morning, and set at 7:35 AM. (All times Pacific Standard Time.)

That means Santa will be making his run this year in the light of the full moon.


There won't be another full moon on Christmas until 2034, so I hope you will be able to make the full moon a part of your Christmas Eve or early Christmas morning.


The December full moon is called the Cold Moon, for obvious reasons, or the Longest Night Moon, for its proximity to the Winter Solstice. But this year we can without hesitation call it what it is: the Christmas Moon.

  1. My fly fishing calendar says the full moon is the 26th. That's the last time I buy one of those calendars.
