Full moon set for Christmas 2015–the first time since 1977. It will also not happen for a long time to come..
It will be full at 6:11 a.m. EST on December 25th, according to Fred Espenak with NASA. A Christmas full moon will not happen again until 2034.
December’s full moon is called the Full Cold Moon, or the moon before yule.
And it will make for a good scene as Santa Claus crosses the sky with Rudolph guiding his sleigh..
