Quick answer

The Cold Moon is the traditional name for the December full moon, when winter sets in across the Northern Hemisphere. It is also called the Long Night Moon, because it falls close to the winter solstice and stays above the horizon for a long time. Spiritually, it is read as a moon of stillness, rest, reflection and turning inward as the year closes.

Times are US Eastern Time (ET), when the moon is exactly full or at the exact phase. It looks full for about a night either side.

On a December evening the sky goes dark before you have left work, and when you step outside the cold has a sharpness that November did not. Then you look up and the full moon is already high, bright enough to throw shadows on the snow or the bare ground.

That is the Cold Moon. The name appears in the Old Farmer's Almanac list of traditional full moon names, which are attributed to Native American and early colonial traditions, and it simply says what December feels like. It also has a second name, Long Night Moon, that comes with real astronomy: close to the solstice, this full moon behaves differently from any other of the year. Below you will find the name, the sky, the meaning and a few quiet ways to mark it. Exact dates are in the table.

Why is it called the Cold Moon? Origin and other names

The name is the plainest in the whole calendar. December is when winter cold truly arrives across much of North America and northern Europe, and the full moon of this month became known as the Cold Moon. It is attributed to Native American and early colonial traditions, and it shows up in the Old Farmer's Almanac list, which popularized the whole set of seasonal names.

The other well-known name is Long Night Moon. It is not poetry alone. The December full moon sits close to the winter solstice, the longest night of the year in the Northern Hemisphere, and since the full moon is in the sky for the whole night, a long night means a long moonlit stretch. Both names, Cold and Long Night, describe the same moon.

In some lists you may also see Moon Before Yule, a name that refers to the Yule season in northern European tradition. Like the others, it is a description of the time of year and not an astronomical term. The Cold Moon is simply the full moon that falls in December.

When is the Cold Moon and why it rides so high

The Cold Moon is the full moon that falls in December. The table below gives the exact date and time for each coming year, in US Eastern time, and it is usually in the same fortnight as the winter solstice, around December 21.

Here is what makes it special. A full moon sits opposite the Sun in the sky. At the winter solstice the Sun is at its lowest in the Northern Hemisphere, so a full moon near that date is at its highest. It climbs high overhead, to roughly the height the midsummer Sun reaches, and it is above the horizon for far longer than a summer full moon, which barely clears the trees.

The result is a bright, small-looking white moon that hangs overhead through the long dark hours. Its light falls on snow with a blue-white clarity. Because it is high, you lose the orange color and the big horizon look of an autumn moon, but you gain the longest viewing window of the year. In the Southern Hemisphere the situation is reversed: it is a summer moon, low and short.

Dress warmly, and try a short look at midnight, when it is highest.

Cold Moon spiritual meaning: stillness, rest and looking inward

The Cold Moon meaning follows the season. December is the point in the year when nature slows down, the days are shortest, and many cultures hold festivals of light to push back the dark. People who read symbolism into the moon see a moon of inward attention.

  • Stillness. Fields are dormant, animals are sheltering. The moon invites you to rest without guilt.
  • Reflection. With the year ending, it is natural to look back. What did you learn, and what did it cost?
  • Endurance. Cold is a test of preparation and patience. The symbol points to what keeps you going when conditions are hard.
  • The long dark and the turning. The longest night is also the point after which days begin to lengthen. Many people find hope in the fact that the dark has a limit.
  • Quiet strength. A high white moon is steady and calm. It does not warm anything, and it still gives light.

None of this predicts what the coming months will bring. Think of the Cold Moon as permission to slow down and take stock, rather than a push to do more. If the season feels heavy, that is worth taking seriously. A doctor or counselor is the right support for low mood that lingers, and no moon can replace them.

Cold Moon rituals and ideas for a long winter night

The Cold Moon suits slow, indoor-and-outdoor practices that center on warmth and reflection.

  • Year-in-review journal. Write down the year's three hardest moments and three brightest ones, and what each taught you. Do not rush it, since the night is long.
  • Release list. Write what you want to leave in the old year, then tear or safely burn the page. Many people do this now because the year is ending.
  • Candle practice. Light one candle and sit with the lights off. Think of it as a small counterweight to the longest night.
  • Short moon-bathing. Step outside in the cold for five minutes, notice your breath and the shadows the moon casts, then go back in for something warm.
  • Set a gentle intention for the new year. Choose a word rather than a list of resolutions. Rest, steady or simple, for example.
  • Charge crystals. Clear quartz, selenite and moonstone are common choices for a winter stillness theme. People set them in the window overnight, and it is a tradition and not a proven effect.
  • Warm gathering. Share soup, tea or a meal with someone you love.

The point is not to produce anything. A quiet evening counts.

Cold Moon in love and relationships

December can magnify relationships. There is more time together, more family, more memory. The Cold Moon is often read as a moon of closeness, honesty and warmth against the cold.

If you are in a relationship, this is a good time for a slow evening with no agenda. Review the year together, what you are proud of and what you would like to do differently, and plan a single small thing for the new year. The long night is a natural reason to stay in and talk.

If you are single, especially if the holidays make that feel loud, the Cold Moon suggests treating solitude as a rest and not a gap. Many people use this moon to write a note of appreciation to themselves, or to reach out to friends and family they have not talked to in a while.

If you are healing from a breakup or a loss, December can be hard, and the long dark is a fair place to feel what you feel. The symbol of the solstice, the dark that turns, may be a comfort, but it is only a symbol. If the weight does not lift, please talk to someone you trust or a professional.

Whatever your situation, the Cold Moon values warmth you can actually give: a call, a meal, a word of thanks.

Cold Moon folklore: Yule, the solstice and astrology

Midwinter has drawn festivals in almost every northern culture, and many of them are about light in the dark. Yule in northern Europe, and Christmas, Hanukkah, Dongzhi in East Asia and other celebrations all cluster around the solstice. The Cold Moon sits in the middle of this season, which is why people often tie it to gatherings, candles and the idea of the year turning.

The Moon Before Yule name is a direct example. For people who counted months by the moon, this was the moon before the midwinter festival, and the full moon was a practical source of light on the longest nights.

There is a quiet scientific footnote too. The moon follows nearly the same path as the Sun, only reversed in season, which is why the winter full moon runs high and the summer full moon runs low.

In astrology, the sign of the December full moon varies with the date each year, so check an ephemeris for this year. The folk reading needs no chart: it is a bright, cold moon in a long night.

Frequently asked questions

Why is December's full moon called the Cold Moon?

Because December is when winter cold fully arrives across much of North America and northern Europe. The name is attributed to Native American and early colonial traditions and appears in the Old Farmer's Almanac list. It is a seasonal description and not an astronomical term, and it names the full moon that falls in December.

Why is the Cold Moon also called the Long Night Moon?

The December full moon falls close to the winter solstice, the longest night of the year in the Northern Hemisphere. A full moon is in the sky all night, so on a long night it is visible for many hours. The moon also rides high then, so it stays up for a particularly long time.

Why does the Cold Moon appear so high in the sky?

A full moon is opposite the Sun. In December the Sun is low in the Northern Hemisphere, so the full moon opposite it is high. It follows a long arc above the horizon, unlike the low summer full moon. In the Southern Hemisphere, where December is summer, it is the reverse.

Is the Cold Moon a good time for setting intentions?

People often use it that way, particularly for reflection on the past year and a gentle intention for the next. Because it falls near the solstice and the end of the year, it suits choosing a single word or habit rather than a long list. It is a reflection practice, not a guarantee of results.

Is the Cold Moon a supermoon?

Only in some years. A supermoon is a full moon near its closest point to Earth, appearing about 14 percent larger and up to about 30 percent brighter than the smallest full moon. Whether December's full moon qualifies depends on the year, so check the dates and notes below.
