Libra days lean toward harmony, beauty, and company. Tact comes easily; firm decisions do not. A fair compromise is worth more today than a quick win.
Waning crescent
Only a crescent remains, visible in the eastern sky before sunrise. The lunar cycle is closing. In lunar tradition, these quiet days suit rest and wrapping up—the next new moon is near.
On its monthly path across the sky, the Moon is now descending: seen from the Northern Hemisphere, each day it crosses the sky a little lower than the day before. In planting tradition, the descending Moon draws strength toward the roots—a time for planting, transplanting, and pruning.

- Day character
- Clear and windy
A light, airy day in Libra is easy and sociable, a fitting time for meetings and for work that needs a good eye.
Lunar day 24
The twenty-fourth lunar day favors physical strength and building: construction, repairs, and training.
Lunar days are counted from the new moon: day 1 begins at the new moon, and a cycle has 29 or 30 of them. Tradition gives each day its own character.
Health by lunar tradition
In lunar tradition, extra care goes to the hips, kidneys, and urinary bladder.
Under a waning Moon, rest serves the kidneys and hips, and a light evening meal helps the body unwind.
On Libra days, tradition says the kidneys are more sensitive to cold, so keep the lower back warm.
Do not put off a trip to the bathroom today; the bladder prefers not to wait.
December is hard on sleep and digestion: keep bedtimes regular, even between holiday parties. Balance dry indoor heat with fresh air and fluids.
Food by lunar tradition
- Favored today
- Fats and oils
Libra days belong to fats and oils. Tradition favors good fats such as nuts, seeds, and fish, and advises caution with fried food, which can feel heavy today.
With the Moon waning, tradition favors plenty of plain water or unsweetened nettle tea.
In lunar lore, the last days before the new moon prepare the body for a new cycle.
December offers the winter classics: cabbage, beets, dried fruit, nuts, and citrus for vitamin C. Between holiday feasts, give the body lighter days too.
Reach for seasonal foods that suit the day: nuts, poppy seeds, and butter in holiday baking.
Tip of the day: a spoonful of good cold-pressed oil, flaxseed or olive, on a salad; tradition says the body makes the best use of fats today.
Garden by the moon
- Plant part
- Flower
December lets the soil rest: beds covered with leaves or evergreen boughs come through winter better. Check stored produce and tools, and keep the bird feeders full. Cress grows on the windowsill, and next year’s bed plan grows in the warmth of the house.
Libra days are flower days: roses, bulbs, and flowering vegetables such as broccoli get the attention.
Under a waning Moon, tradition says, the parts of plants below ground take the lead.
A waning Moon in winter favors houseplants: repot them, remove dry leaves, and in the cellar you can prepare rootstocks and scions for grafting.
This is the time to harvest Brussels sprouts.
Seasonal advice is for the Northern Hemisphere’s temperate zone; south of the equator, swap the seasons. For the best days of the month, see planting by the moon and the lunar hair calendar.
