This page answers one simple question — where the Moon is today — with exact data: phase, illumination percentage, the sign it's crossing, and the day of the lunar cycle. Everything is calculated from the Swiss Ephemeris, the astronomical reference behind professional astrology software, and recalculated every night.

Why care? Tradition ties each phase to an energy: the waxing moon carries launches and momentum, the full moon amplifies emotions and brings things to completion, the waning moon helps finish, sort, and release. These aren't laws of physics — they're an observational rhythm many people find useful for planning. We present them honestly as exactly that.

The eight Moon phases, and what tradition ties to them

The full cycle runs about 29.5 days. Tradition gives each phase a tone — an observational rhythm, not a law:

🌑 New moonthe zero point: intentions, starts, plans made in quiet
🌒 Waxing crescentfirst steps: testing, initiating, recruiting support
🌓 First quarterthe first obstacle: decisions, adjustments, persistence
🌔 Waxing gibbousthe ramp-up: refine, correct, hold the effort
🌕 Full moonthe peak: visible results, high emotions, celebration
🌖 Waning gibbousthe sharing: transmit, thank, gather the feedback
🌗 Last quarterthe sorting: release what didn't work, close the files
🌘 Waning crescentthe rest: slow down, sleep more, prepare the next cycle

Cutting your hair by the Moon: what tradition says

It's the most persistent lunar custom: cut during the waxing moon for fast, vigorous regrowth; cut during the waning moon so the shape holds longer — handy for short cuts and tidy ends. The full moon has a reputation for dramatic makeovers; the new moon, for being a day to skip — hair and decisions alike.

Honestly: science hasn't measured any lunar effect on keratin. But generations of stylists and clients keep this calendar — and a standing ritual appointment with your hair has at least one proven virtue: the hair gets regular care. Today's phase is at the top of this page; feel free to make it your salon calendar.

The Moon in the garden

Lunar gardening follows one simple logic: during the waxing moon, sap is said to rise — sow and plant what grows above ground (tomatoes, greens, flowers); during the waning moon, energy heads down — root crops (carrots, radishes, bulbs), pruning, and soil work. Full moon and new moon days are pauses: observe, don't intervene. Plenty of gardeners swear by this rhythm; others see just a pleasant calendar of consistency. Both camps grow the best tomatoes on the block.

The Moon and sleep: what studies show

Here research does have something to say: several studies observed slightly longer sleep onset and reduced deep sleep around full-moon nights in part of the population — a modest effect that varies by person, but documented. Night brightness plays its role: a full moon gets through thin curtains. If your full-moon nights run restless, the fixes are simple: truly blacked-out bedroom, screens off an hour before, slightly earlier bedtime those three nights. The dates of the next full moons are listed above.

What's a lunar day for?

The cycle splits into 29 or 30 "lunar days," each starting at moonrise. Tradition — especially vivid in Eastern European astrology — gives each one a tone: days of momentum, days of caution, days of review. Without turning it into scripture, it's a reading frame many find useful for pacing tasks: launch on the momentum days, tidy on the sorting days. The current lunar day number is in the banner at the top.

Frequently asked questions

Is the Moon waxing or waning today?

The exact answer is at the top of this page: it's recalculated nightly from the Swiss Ephemeris — the same astronomical data professional software uses. It's not a copied table; it's a calculation.

What's the difference between a full moon and a new moon?

At the full moon the disk is fully lit: tradition reads it as an emotional peak and the culmination of what was started. At the new moon the Moon is invisible: the moment for intentions and fresh starts. Between the two, the Moon waxes and wanes on a cycle of about 29.5 days.

Does the Moon's sign really change every couple of days?

Yes: the Moon crosses the whole zodiac in about a month — roughly two and a half days per sign. That's why the mood shifts so fast: the Moon in Aries doesn't feel like the Moon in Pisces. Today's sign is shown above.

Are these calculations right for my time zone?

The data is calculated for midday. On boundary days the phase date can shift by one day depending on your zone — for the edge cases, check the day before and after. For everyday use, the precision is more than enough.
