Understanding today’s moon phase
The tracker at the top of this page gives you an instant snapshot of the current lunar phase – the exact name (e.g. Waxing Gibbous), the percentage of the Moon’s surface lit up right now, and how many days old the current cycle is.
The current phase of the moon changes gradually every day. As the Moon orbits Earth, the angle between the Moon, Earth, and Sun shifts and that’s what changes how much of the lit side we can see from the ground.
The tracker also shows the daily moon cycle in context: where today sits within the full 29.5-day journey from new moon back to new moon. That bigger picture is what makes the data genuinely useful, not just a curiosity.
The 8 Moon Phases
The eight main moon phases are: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent.
New Moon: The moon is completely unilluminated and invisible from Earth. It is the beginning of the lunar cycle. The illumination is 0%
Waxing Crescent & Waxing Gibbous: The moon’s illumination steadily grows day by day as it builds toward peak brightness.
First Quarter & Third Quarter: The classic half-moon phases, which are absolutely perfect for telescopic viewing of lunar craters. The illumination is 50%.
Full Moon: The brightest night of the month, when the moon is visible completely (Full). The illumination is 100%
Waning Gibbous & Waning Crescent: The illumination fades as the moon slowly prepares to start a new cycle.
The Lunar Cycle
The moon completes one orbit around Earth every 27.3 days. This is called the sidereal month. But because Earth also moves around the sun, the moon needs about 29.5 days to return to the same phase as seen from Earth. This is the synodic month, and it drives the lunar calendar.

Moon data: illumination, age, sign & more
Moon Phase
The moon phase tells you where the moon sits in its 29.5-day synodic cycle, from new moon through waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent.
Moon Sign
The moon sign shows which zodiac sign the moon occupies right now. The moon moves through all 12 signs roughly every 27.3 days, spending about 2.5 days in each.
Illumination
Illumination measures how much of the moon’s visible surface reflects sunlight toward Earth. At new moon it is 0%. At full moon it reaches 100%.
Moon Age
Moon age counts the days elapsed since the last new moon. The lunar cycle runs 29.5 days from new moon to new moon.
Constellation
The constellation shows which background star pattern the moon currently passes in front of, based on its position in the sky. The moon moves through the constellations of the ecliptic over its monthly orbit.
Moon Angle
The moon angle (also called the angular diameter or subtended angle) tells you how large the moon appears from Earth. A higher angle means the moon is closer and looks bigger.
Moon Distance
Moon distance measures how far the moon is from Earth at this moment. This varies because the moon follows an elliptical orbit. At perigee (closest approach) it is about 356,500 km away.
Sun Angle & Sun Distance
The sun angle shows the sun’s current position in the sky relative to the horizon. It determines daylight hours and solar elevation at your location.
Earth’s distance from the sun changes throughout the year as Earth follows its own elliptical orbit.
Can you see the moon tonight?
Can you see the moon tonight? It depends on two things: the phase and your local conditions.
- New moon: No – the Moon is up during the day and invisible at night.
- Waxing crescent: Yes, briefly after sunset in the western sky. A crescent moon tonight is one of the most beautiful sights – look west just after dark.
- First quarter: Yes, from afternoon until around midnight.
- Full moon: Yes, all night – rises at sunset, sets at sunrise.
- Waning phases: Rises progressively later; best seen in the early morning hours.
Cloud cover, light pollution, and your horizon all affect visibility. A bright moon tonight (near full) can wash out stargazing but is perfect for a walk without a torch. A dark moon tonight (near new) means excellent conditions for deep-sky observing – stars and galaxies pop without lunar interference.
The Elliptical Orbit of the Moon
The moon does not orbit Earth in a perfect circle. Its path is an ellipse, which means its distance from Earth changes constantly.
At perigee, the closest point in its orbit the moon can appear up to 14% larger and 30% brighter than at its farthest point. When a full moon coincides with perigee, it is commonly called a supermoon.
At apogee, the farthest point the moon appears smaller. If a total solar eclipse occurs when the moon is near apogee, the moon cannot fully cover the sun, producing an annular (ring) solar eclipse.
Why Track the moon phase?
People track the moon for more reasons than you might expect:
- 🔭 Astrophotography – A new or crescent moon means dark skies; ideal for shooting nebulae and galaxies without glare.
- 🌱 Gardening – Biodynamic growers plant by lunar phases; root crops are traditionally sown during waning phases, leafy crops during waxing.
- 🎣 Fishing – Many anglers swear by full and new moon periods for increased fish activity, linked to tidal forces.
- 🌌 Stargazing – Knowing the moon phase tells you how dark your sky will be – critical for planning any observing session.
- 🧘 Spiritual practice – New and full moons anchor rituals, journaling, and intention-setting in many traditions.
- 🌊 Tide planning – Spring tides (highest highs, lowest lows) occur at new and full moon; neap tides at the quarters. Essential for coastal activities.
FAQ’s ❓
What is the current moon phase right now?
The live widget at the top of this page shows the current moon phase, updated in real time. It displays the phase name, illumination percentage, moon age, and more.
What does moon illumination percentage mean?
Moon illumination is the percentage of the Moon’s Earth-facing surface that’s lit by the Sun at this moment. 0% = new moon (dark), 100% = full moon (fully lit). At first and last quarter, it’s 50%.
What is moon age in days?
Moon age counts the days since the last new moon. It resets to 0 at each new moon and climbs to about 29.5 before the next one begins. It’s the most precise way to know exactly where you are in the lunar cycle.
What zodiac sign is the moon in today?
The Moon moves through all 12 zodiac signs roughly every 27–28 days, spending about 2.5 days in each. The tracker shows the current moon zodiac sign in real time. It changes frequently – check back every couple of days for an update.
How often does the moon change phase?
The Moon doesn’t flip between phases instantly – it transitions continuously. The four primary phases (new, first quarter, full, last quarter) each occur once per 29.5-day cycle, roughly a week apart. The four intermediate phases (waxing/waning crescent and gibbous) fill the gaps between them.
What is the difference between a waxing and waning moon?
A waxing moon is growing – illumination is increasing from new moon toward full moon. A waning moon is shrinking – illumination is decreasing from full moon back toward new moon. “Wax” and “wane” are old English words for grow and diminish.
Can I see the moon every night?
Not quite. Around the new moon, the Moon is above the horizon during the day and invisible at night. For a few nights around new moon, you won’t see it at all after dark. Every other night of the month, the Moon is visible for at least part of the night – though cloud cover and your local horizon can still get in the way.
