About the Waxing Gibbous
Between first quarter and full moon the Moon is waxing gibbous: more than half lit and growing each night. It rises in the afternoon, dominates the evening sky and sets after midnight.
Its brightness climbs quickly during this phase, from about a tenth of full-moon brightness at first quarter to full within a week, because the Moon's rough surface reflects most strongly when the Sun is directly behind the observer.
Lore and folklore
The swelling moon was traditionally a time of increase: livestock fattened, crops filled out, and anything meant to grow was tended now. In some traditions it was the best time to gather herbs, when their vigour was thought to peak.
Gibbous comes from the Latin for hump-backed, a plain description of the bulging shape.
Trivia
- The Moon's brightness is not proportional to the lit area; a half moon is only about a tenth as bright as a full moon.
- The waxing gibbous is the phase most often noticed in daytime, high in the afternoon sky.
- Around this phase the bright crater rays, streaks of ejected rock, become obvious to the naked eye.
- The gibbous Moon rises later each day by anything from 30 to 70 minutes depending on the season.

This month's full moon: the Cold Moon
The December full moon, when winter cold takes hold and nights are longest.
The Long Night Moon, for the night nearest the winter solstice, and the Moon before Yule are older names. It is the highest-riding full moon of the year in the northern hemisphere, opposite the low December sun.
Lore
December's moon comes with the deepest cold and the longest nights, hence the Cold Moon and Long Night Moon. In Anglo-Saxon tradition it was the Moon before Yule, and its light on snow made the long nights unusually bright.
Trivia
- The Cold Moon rides highest of all full moons in the northern hemisphere, opposite the low solstice Sun.
- Around the December solstice the full moon is above the horizon for more than 15 hours at 50 degrees north.
- The Cold Moon is usually the last full moon of the year, but some years a thirteenth follows it as a Blue Moon.
Gardening by the Moon in December 2025
- Dec 1 to Dec 4 · Fruiting crops: Sow above-ground crops whose seeds form inside the fruit: beans, peas, tomatoes, peppers, squash, cucumbers, melons. Graft, repot and sow lawns.
- Dec 5 to Dec 11 · Root crops: Plant root crops and anything that overwinters: carrots, beets, potatoes, onions, garlic, bulbs, perennials, trees and shrubs. Prune to slow growth.
- Dec 12 to Dec 19 · Rest and tend: Rest days for the soil: weed, cultivate, turn compost, harvest crops for storage, prune to discourage regrowth, prepare beds. Avoid sowing.
- Dec 20 to Dec 27 · Leafy crops: Sow leafy crops and above-ground annuals whose seeds form outside the fruit: lettuce, spinach, cabbage, broccoli, celery, herbs. Transplant seedlings. Mow to encourage growth.
- Dec 28 to Dec 31 · Fruiting crops: Sow above-ground crops whose seeds form inside the fruit: beans, peas, tomatoes, peppers, squash, cucumbers, melons. Graft, repot and sow lawns.

How to read this moon calendar
Each day shows the Moon as it looks from Hacienda Heights at midday local time, with the illuminated percentage, moonrise and moonset. Days with a principal phase show the exact local time the phase occurs. Because the Moon moves about 50 minutes later each day, roughly once a month there is a date with no moonrise or no moonset at all.
The eight phases of the Moon
New Moon
The Moon sits between Earth and the Sun. Its lit side faces away from us, so it is invisible in the night sky. A new lunar month begins.
Waxing Crescent
A thin sliver grows each evening after sunset. Look low in the west shortly after dusk.
First Quarter
Half the disc is lit. The Moon rises around midday and sets around midnight, so it is high in the sky at sunset.
Waxing Gibbous
More than half lit and growing. It rises in the afternoon and shines most of the night.
Full Moon
The whole face is lit. It rises at sunset and sets at sunrise. Each full moon carries a traditional name.
Waning Gibbous
The lit portion shrinks. It rises after sunset and is still up in the morning sky.
Last Quarter
Half lit again, on the opposite side. It rises around midnight and is best seen in the early morning.
Waning Crescent
A thinning sliver before dawn in the east, fading toward the next new moon.
