December's Full Cold Moon

Full Cold Moon - OFA

The Full Moon for December 2018 rises on the 22nd—and will be close to full (95%) on Christmas eve. Traditionally, this Moon was called the Full Cold Moon. Read why—plus, see more Moon facts and folklore.

December Full Moon Names

In Native American cultures which tracked the calendar by the Moons, December’s Full Moon was known as the Full Cold Moon. It is fittingly associated with the month when the winter cold fastens its grip and the nights become long and dark.

This Full Moon is also called the Long Nights Moon by some Native American tribes because it occurs near the winter solstice—the day with the least amount of daylight.

Well, the moon is a fun piece of space sculpture to keep your eyes on. Ask some NASA astronauts if its really a planet. Haaaaa. I love a mystery! Am I watching a "MOON"? Or could it be watching ME? Its all FUN!!

Satellite, star, or planet....

Hey for that last few mornings here in SE Minnesota, looking straight west, I've seen a bright object in the sky that at times, seems to be blinking. Do you think it is a star, satellite, or planet? Thanks!

Blinking Object

If the object does not appear to move, then it is likely a star. The blinking or twinkling you see is called scintillation, and happens when the star’s light passes through the Earth’s atmosphere. Differing air densities of the atmosphere make the light appear to twinkle. This effect is strongest closest to the horizon, as the light must pass through more of the atmosphere than it would directly overhead. 


Is the new moon a full moon or a sliver of a moon?

What is the New Moon?

The “New Moon” is technically when there is 0% illumination from the Sun. You can not see the Moon. However, many photos will show a slight sliver (very near the new Moon) or you’d be looking at blackness! With a New Moon, the Sun and Earth on opposite sides of the Moon so all three are aligned, leaving the side of the Moon that faces Earth in complete darkness. See our Moon Phases Calendar and you’ll notice the day of 0% illumination in your time zone is labeled as “New Moon.” https://www.almanac.com/astronomy/moon/calendar

Full moon

What is a cold full moon & what does it mean??

cutting hair.

For thousands of years, people have known the best time to initiate any project is when the moon is waxing from dark to full. I always believed cutting hair fits into this category. I believe the Almanac states this too, but also gives confusing dates?? Also what is the emphasis all the sudden on Lunar haircutting, I think it stems from the Lunar hair cutting craze put out by that henna company M.M. People, their calendars are wrong and I don't know where they are getting their information. I think they are making it up as a lot of their products are supposed to be based on Traditional Alternative Medicine methods, but they are not, not even close. Please don't go for the baloney - it is just marketing to try to get you to buy their product line at ridiculously HIGH PRICES...They are not experts as their serums and elixirs are B.S. You could ez make them yourself for 99% less of the price they charge for one.

For Harvesting above ground

what does that mean??? what can I plant on those days if anything,.

Hi Linda,

Hi Linda,

You can plant below-ground crops like radishes, carrots, potatoes in the waning of the Moon (between a full Moon and new). The Moon will be new on Dec. 11. After Dec. 11 plant above-ground crops (tomatoes, peas, pepper etc.).

Hair cutting to have it grow

I think your hair will grow if you cut it at anytime... And even if you don't cut it

Why are the comments saying

Why are the comments saying the best time to cut hair is at full and new moon. But the almanac picks days not on a full or new moon?

Hi Scuffy, The Almanac

Hi Scuffy,
The Almanac believes that cutting the hair during a waxing Moon (between new and full) encourages growth. Cutting the hair during a waning Moon (between full and new) discourages growth. The very best days to cut hair to encourage growth in Dec. are 3, 4, 30,31. Very best days to cut hair to discourage growth are Dec. 15 and 16.

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.

My mother used to clip the ends of my hair during a full moon. It always grew back richer and fuller.
