Full Moon for December 2020

Bundle Up for December's Full Cold Moon!

November 29, 2020
Full Cold Moon - OFA

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

When to See December’s Full Moon

December’s Cold Moon reaches peak illumination on Tuesday, December 29, 2020, at 10:30 P.M. EST

Start looking for the full Moon just before sunset as it begins to peek above the horizon. To find the exact time that it will appear in your area, consult our Moonrise Calculator.

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

Why Is It Called the Cold Moon?

The Moon names we use in The Old Farmer’s Almanac come from Native American, Colonial American, or other traditional sources passed down through generations. A variety of Native American societies traditionally used the monthly Moons and nature’s corresponding signs as a calendar to track the seasons.

Today, December’s full Moon is most commonly known as the Cold Moon—a Mohawk name that conveys the frigid conditions of this time of year, when cold weather truly begins to grip us.

Other names that allude to the cold and snow include Drift Clearing Moon (Cree), Frost Exploding Trees Moon (Cree), Moon of the Popping Trees (Oglala), Hoar Frost Moon (Cree), Snow Moon (Haida, Cherokee), and Winter Maker Moon (Western Abenaki).

This full Moon has also been called the Long Night Moon (Mohican), as it rose during the “longest” nights of the year, which are near the December winter solstice. This name is also fitting because December’s full Moon shines above the horizon for a longer period of time than most full Moons.

In Europe, ancient pagans called the December full Moon the “Moon Before Yule,” in honor of the Yuletide festival celebrating the return of the sun heralded by winter solstice.

Hair should be cut while the

Hair should be cut while the Moon is increasing. For beauty it should be in Taurus or Libra, and if applying to a harmonious aspect of Venus, so much the better. For luxuriant growth it should be in Cancer, Scorpio or Pisces. Treatments to increase growth should be started while the Moon is increasing in Scorpio, subsequent treatments while increasing in Cancer, Scorpio or Pisces.

My mother looked at my face

My mother looked at my face when she would look at the moon on the day of the first moon for good luck.

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.
