Waxing Moon
Waxing means the illuminated part is growing from night to night. The Moon is moving from New Moon toward Full Moon, so it generally becomes brighter and easier to see in the evening sky.
Moon phase guide
Want to know the Moon phase tonight? This guide shows the current lunar phase, how much of the Moon is illuminated, whether it is waxing or waning, and how to inspect the Moon on the live Celesiq map.
Quick answer
Tonight's Moon phase is being calculated for your device time zone.
Moon phase tonight
The default result uses tonight around 22:00 in your device time zone. You can also choose another date to preview a future Moon phase or look back at a past lunar phase.
Illumination and lunar age will appear here.
The waxing or waning direction will appear here.
The Moon phase tonight tells you how much of the Moon's sunlit half is visible from Earth. A New Moon is close to the Sun in the sky and is mostly dark from our point of view. A Full Moon is opposite the Sun and appears almost fully illuminated.
Between those two moments, the Moon moves through crescent, quarter and gibbous phases. The phase changes gradually every night, so even one or two days can make the Moon look noticeably different.
The Moon phase is essentially the same everywhere on Earth at the same moment. Someone in Amsterdam and someone in Sydney are looking at the same Moon phase, even though their local date, viewing angle and moonrise time may be different.
What does change by location is the Moon's position in your local sky. The Moon may be high above the horizon for one viewer and below the horizon for another. The lit side can also appear tilted or flipped depending on your hemisphere and viewing angle.
Waxing means the illuminated part is growing from night to night. The Moon is moving from New Moon toward Full Moon, so it generally becomes brighter and easier to see in the evening sky.
Waning means the illuminated part is shrinking from night to night. The Moon is moving from Full Moon back toward New Moon, and it is often easier to see late at night or before sunrise.
The Moon does not produce its own light. It reflects sunlight. Half of the Moon is always lit by the Sun, but as the Moon orbits Earth, we see different amounts of that lit half.
A complete lunar phase cycle takes about 29.5 days. This is called the synodic month. That is why the Moon phase tonight will be slightly different from tomorrow night, and why Full Moons and New Moons do not happen on the same calendar date every month.
Live map
The Moon phase tells you how the Moon is illuminated. The live map shows the Moon's apparent subpoint on Earth, together with the Sun and the day/night pattern.

The Moon phase changes how dark the sky feels. A bright Full Moon can wash out faint stars, meteor showers and deep-sky objects. A thin crescent or New Moon gives darker conditions and is usually better for faint objects.
For casual observing, the Moon phase also helps you know what to expect before you step outside. A crescent Moon looks very different from a gibbous Moon, and a nearly Full Moon can dominate the sky.
The calculator uses a standard approximate lunar cycle based on the average 29.5-day synodic month. It is useful for educational skywatching and planning, but exact lunar ephemerides can vary slightly because the Moon's orbit is not perfectly circular.
For photography, telescope planning or scientific work, compare the result with official astronomical references. For everyday questions like "what is the Moon phase tonight?", this estimate is normally close enough to understand what you will see.
The answer appears in the quick check above. It shows tonight's phase name, the approximate illumination percentage and whether the Moon is waxing or waning.
Mostly yes. At the same moment, the lunar phase is essentially the same worldwide. Your location changes moonrise time, moonset time, altitude and the apparent tilt of the Moon.
A New Moon or thin crescent is usually best for stargazing because the sky is darker. A Full Moon is beautiful, but it can make faint stars, meteor showers and deep-sky objects harder to see.
Percent illuminated estimates how much of the Moon's visible disk is lit by the Sun. It is near 0% at New Moon and near 100% at Full Moon.
The lit side points generally toward the Sun, but your location, latitude, time of night and viewing angle change how that lit side appears in your local sky.
Celesiq lets you follow the Moon, Sun, planets and spacecraft on a live world map. Use it to inspect Moon phases, compare the Moon with the day/night line, and move through time.
