Christmas Full Moons

For those who celebrate Christmas, it can also be interesting to know when the holiday will also coincide with a full moon. In years where the dates are close, depending on your time zone, the full moon may overlap directly with Christmas, fall on Christmas Eve, or happen directly after the holiday.

Most recently, there was a Christmas Full Moon in 2015 for both the Eastern Time Zone and UTC. And the next Christmas Full Moon will be in 2034 for those two time zones as well.
