We all know how that festive jingle about Rudolph ends on that “one foggy Christmas night.” Perhaps you’ve even thumbed up the holiday standard on your Pandora station. Well, this year Rudolph might actually get his first path-lighting break in a long, long time thanks to a not-often-seen astrological coincidence. This holiday, you’re gonna want to leave those “chestnuts roasting over an open fire” and venture outside to check out this celestial event that hasn’t happened in almost 40 years.

Winter moonlight

This year, a full moon will be rising on Christmas Eve with peak moon-time (that’s a thing!) falling at 6:11 AM EST on Christmas day. The last time this event happened was back in 1977 — that’s 38 years ago. And we won’t be seeing it again, according to the Weather Channel, for another 19 years in 2034.

This December full moon goes by many nicknames like “Oak Moon,” “Cold Moon” or “Long Night’s Moon” (full moon naming tradition dates back to Native American tribes). And this year’s moon is particularly special because it’s the only moon all year that will be in the sky all night long from sunset to sunrise.

Guess the universe really doesn’t want Santa to lose his way on Christmas.
