There’s nothing magical about the holiday light show, CNN meteorologist Chad Myers said. It’s just science.

“The moon cycles every 29.5 days, meaning every 29.5 days, there will be a full moon. … So, on average, every 29.5 years, a full moon will land on December 25,” Myers said.

December’s full moon is called the Full Cold Moon because it occurs during the start of winter, NASA said in post about the rare Christmas moon.

Moonrise is at 4:37 p.m. PT Christmas Eve, just before sunset. The moon will peak at 3:11 a.m. PT on Friday, according to NASA.

The next Christmas full moon won’t occur until 2034, NASA said.
