The moon moves through eight phases roughly every 29.5 days: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter and waning crescent. In ritual, the waxing half is traditionally used for beginnings and growth, the full moon for gratitude and release, and the waning half for letting go and rest.
Why the moon changes shape
The moon makes no light of its own. One half of it is always lit by the sun, and as the moon travels around the Earth we see more or less of that lit half. At the new moon it sits roughly between us and the sun, so the side facing us is dark. At the full moon it is on the far side of the Earth from the sun, and we see its whole bright face. The complete cycle, from one new moon to the next, takes about 29.5 days.
Waxing means growing and waning means shrinking. In the UK and the rest of the northern hemisphere, a waxing moon is lit on the right-hand side and a waning moon on the left. "Gibbous" describes a moon that is more than half lit but not quite full.
The moon in folklore and ritual
People have planted, gathered and kept time by the moon for as long as there are records, and British folklore is full of small moon customs. Many people grew up hearing that it was lucky to see the new moon over your right shoulder and unlucky to see it first through glass, and some would turn over the coins in their pocket for luck when they first spotted it.
Many modern practitioners use the cycle as a gentle monthly rhythm: setting intentions as the light grows, giving thanks at its fullest and letting go as it fades. It sits at the heart of much everyday hedge magic, and the smaller monthly cycle fits neatly inside the larger turning of the seasonal year.
Moon phases at a glance

The eight moon phases and their meanings
1. New moon
The moon is invisible or very nearly so. Traditionally this is the time for fresh starts, planting ideas and setting intentions.
Ritual idea: sit with a notebook and write three intentions for the month ahead, in the present tense. A moon phases notebook kept just for this makes it easy to look back. Our new moon intention spread is a lovely companion.
2. Waxing crescent
A thin sliver appears low in the western sky after sunset. This phase is associated with hope, first steps and gathering energy.
Ritual idea: take one small, practical action towards an intention. Some people sow a pot of herb seeds on the windowsill as a living symbol of something growing.
3. First quarter
Half of the moon's face is lit. It is often seen as a time of decision and effort, when plans meet their first obstacles.
Ritual idea: light a small spell candle in a colour that suits your aim (our guide to candle colour meanings will help) and name one thing you will do this week to keep going. Stand it on a heatproof surface and never leave it unattended.
4. Waxing gibbous
More than half lit and growing towards full. Traditionally a time for refining, tending and patience.
Ritual idea: read back over your new moon notes and adjust anything that no longer fits. Tidy and refresh your altar, ready for the full moon.
5. Full moon
The whole face is bright, rising in the east around sunset. The full moon is associated with completion, gratitude, celebration and heightened intuition.
Ritual idea: write a list of things you are grateful for, then set your crystals on a windowsill to sit in the moonlight overnight. Our full moon ritual guide has a complete, step-by-step evening.
6. Waning gibbous
The light begins to shrink. Traditionally this is a time for sharing, teaching and giving back.
Ritual idea: pass something on: a book you have finished, a kind word, a little time for a friend. You might also leave a small seasonal offering of seeds or flowers in an offering bowl.
7. Last quarter
Half lit again, this time on the left. This phase is associated with release, forgiveness and clearing out.
Ritual idea: write down a habit, worry or old story you are ready to let go of, then tear the paper into pieces and put it in the compost or recycling. Clearing a single drawer or shelf is a practical echo of the same intention.
8. Waning crescent and the dark moon
A slender crescent rises before dawn, and for a day or so before the new moon it cannot be seen at all. Many practitioners call this the dark moon: a time for rest, reflection and quiet.
Ritual idea: do less. Run a warm bath with a handful of bath salts, have an early night and let the month settle before the next new moon. Gentle, reflective divination such as reading tea leaves suits this inward time well.
How to track the moon
The easiest way is simply to look up. Make a habit of finding the moon in the evening sky during the waxing half, or in the early morning during the waning half, and notice its shape. For exact dates, our moon calendar shows the current phase along with the coming new and full moons.
A couple of names are worth knowing. The Harvest Moon is the full moon nearest the autumn equinox, which rises soon after sunset several evenings in a row and is traditionally said to have given farmers extra light for bringing in the crops. A blue moon, in its popular modern sense, is a second full moon within a single calendar month. It happens only every two or three years, so the phrase "once in a blue moon" feels very apt.
Keeping a moon journal is a lovely way to notice patterns. Note the phase, the weather, your mood and any readings or rituals you tried. Over a few months you may find that you feel more outgoing around the full moon and more inward at the dark moon, or that the moon makes little difference to you at all. Either way, you will know your own rhythm a little better.
Crystals traditionally associated with the moon
Crystals are not needed for moon work, but many people enjoy keeping one on the altar or windowsill. The meanings below are traditional associations rather than proven properties.
- Moonstone takes its name from its soft, moonlike sheen. It is traditionally associated with intuition, new beginnings and the cycles of the moon. An Indian moonstone sphere catches candlelight beautifully.
- Selenite is named after Selene, the Greek goddess of the moon, and is associated with clarity and cleansing. It is soft and can be damaged by water, so keep it dry. A selenite moon cycles charging plate is a popular place to rest other crystals.
- Labradorite flashes with blue, green and gold as it turns in the light. Many people associate it with intuition and change, which makes it a fitting stone for the dark moon. A labradorite palm stone is lovely to hold during quiet reflection.

Bring it home
Working with the moon needs no special equipment: a window, a notebook and a few minutes each week are enough. When you would like to add a little ceremony, a candle, a crystal on the sill or a bowl of seasonal offerings can make each phase feel like a small homecoming. Explore our altar and ritual tools when you are ready.
Questions and answers
What is the difference between a new moon and a dark moon?
Astronomically, the new moon is the moment the moon passes between the Earth and the sun, with its lit side facing away from us. Many practitioners use the term dark moon for the day or so before, when no moon can be seen at all, keeping it as a time for rest and saving the new moon itself for setting fresh intentions.
How long does each moon phase last?
The whole cycle takes about 29.5 days, so if you divide it evenly each of the eight phases covers roughly three to four days. Strictly speaking, the new moon, the quarters and the full moon are exact moments, with the crescent and gibbous phases filling the days between, but in ritual most people work with the day or two around each main phase.
Which moon phase is best for setting intentions?
The new moon is the traditional time for setting intentions, as the light is just about to grow. Many people write their intentions down at the new moon, take first steps during the waxing crescent and look back over them at the full moon. If you miss the new moon, any point in the waxing half of the cycle is traditionally seen as suitable.
Is a waxing moon lit on the left or the right?
In the UK and the rest of the northern hemisphere, a waxing moon is lit on the right-hand side and grows towards full, while a waning moon is lit on the left. In the southern hemisphere this is reversed. Timing is another clue: a waxing crescent appears in the evening after sunset, and a waning crescent in the early morning.
What crystals are associated with the moon?
Moonstone, selenite and labradorite are the stones most often associated with the moon. Moonstone is named for its soft sheen, selenite takes its name from Selene, the Greek moon goddess, and labradorite is linked with intuition and change. These are traditional associations only. Keep selenite dry, as it is soft and can be damaged by water.
