Full Cold Moon - OFA

December’s full Moon rises on December 29, 2020. The original Old Farmer’s Almanac will reveal everything you need to know about the Full Cold Moon and what makes it special. 

The Full Moon in December 2020

Technically, the full Moon reaches peak fullness on December 29, 2020 at 10:28 P.M. EST—and earlier is time zones further west.

(Note: In England, the full Moon date is the 30th at 3:28 A.M.)

Look for the full Moon to appear above the horizon just before sunset. To find the exact time that it will be visible in your area, consult our Moonrise Calculator.

What makes this full Moon special? It’s most distinctive for its high trajectory across the sky, causing the full Moon to sit above the horizon for a longer period of time.

December Full Moon Names

  • December’s full Moon has traditionally been known as the Full Cold Moon by some Native Americans tribes since this is the month that heralds in the cold winter season.
  • This full Moon was also called the Long Nights Moon by Native American groups because it rose during the “longest” nights of the year, which are near the December 21 winter solstice.  The “Long Nights Moon” name is also fitting because December’s full Moon shines above the horizon for a longer period of time that most moons.
  • Ancient European pagans called it the “Moon Before Yule,” in honor of the Yuletide festival celebrating the return of the sun heralded by winter solstice.

I knew the Solstice was on

I knew the Solstice was on its way, (beginning of summer, not winter, if you think about it... all the days start getting longer from this point out-- how's that for a cheery thought?) but I had forgotten the lore about 'hair cuts!' Yesterday I had scheduled, weeks ago, the major trimming for our huge trees, esp. the apples, which you can't trim until after several hard freezes. Well my trees should grow full and fill out this next year, they say, and the wood peckers sure are excited today. The moon last night was spectacular, the night creatures all bathed in blue.

In many traditions things are

In many traditions things are cut on the full moon because living things sre at their fullest. For example native tribes in Mexico harvest roots for medicine on full moon b/c the plant is full, the moon pulls on it the same as the tides, the same as a woman's cycle etc. it would make sense that hair and nails are the same.

On average everyone's hair

On average everyone's hair grows 6" a year -1/2" a month. I trim/cut my hair on the new moon. It is to my knees. Here is what I know- Hair won't grow if you are not eating enough protein -or use too much heat from chemicals or blow drying. Remember - also can't trim or cut hair faster than it grows. so keep it in good condition so you need to trim only a few inches a year.
