What is the Moon Phase Today?

The moon produces no light of its own. Everything we see from Earth is sunlight bouncing off the lunar surface. As the moon completes its orbit around our planet every 29.5 days, the angle between the Sun, Earth, and Moon changes continuously — which is why the lit portion we observe shifts each night in a predictable pattern.

This 29.5-day journey is called the synodic month. It begins at the New Moon, when the moon sits between Earth and the Sun, making it invisible to the naked eye. Over the following two weeks, illumination grows — a process called waxing — until we reach the Full Moon. Then it slowly shrinks, or wanes, back to darkness before the cycle begins again.

The 8 Lunar Phases Explained

New Moon (0–1%): Completely dark and invisible. Tides are at their strongest — called spring tides — because the Sun and Moon align on the same side of Earth.

Waxing Crescent (1–49%): A slim silver sliver appears on the right side. Best seen just after sunset low in the western sky.

First Quarter (50%): Exactly half the moon is lit. It rises around noon and sets around midnight, making it highly visible in the evening sky.

Waxing Gibbous (51–99%): More than half lit and still growing brighter. Visible for most of the night from late afternoon onward.

Full Moon (100%): Fully illuminated. Rises at sunset, sets at sunrise. Creates the highest tides of the month due to the Sun-Earth-Moon alignment.

Waning Gibbous (99–51%): The lit side now slowly shrinks. Rises after sunset and remains visible well into the morning hours.

Last Quarter (50%): Again exactly half lit — but now it is the left side. Rises around midnight and is visible throughout the morning sky.

Waning Crescent (49–1%): A final thin sliver before the cycle resets. Best spotted just before sunrise in the eastern sky.

Why does the moon look different every night?

Because both the Earth and Moon are in constant motion simultaneously. As the Moon orbits Earth and Earth orbits the Sun, the angle of sunlight hitting the lunar surface changes every single day. This causes the lit portion we observe to grow and shrink in a reliable 29.5-day cycle.

Does the moon phase affect human sleep?

Research published in Current Biology found that people take longer to fall asleep and sleep about 20 minutes less around the full moon, even in controlled lab conditions with no windows. The mechanism is still actively debated among scientists, but the correlation across multiple studies is consistent and measurable.

What is a supermoon?

A supermoon occurs when a full moon coincides with the moon being at or near perigee — its closest point to Earth in its elliptical orbit. The moon can appear up to 14% larger and 30% brighter than a typical full moon. The term was coined by astrologer Richard Nolle in 1979 and later adopted widely by astronomers and media.

How accurate is this moon phase calculator?

This tool uses the Julian Date method with a synodic month of 29.53059 days referenced from a known New Moon epoch (January 6, 2000). It is accurate to within a few hours for phase identification. For precise astronomical timing used in scientific applications, consult NASA’s official lunar data tables.

Why does the moon sometimes look orange or red?

When the moon sits near the horizon, its light travels through a much thicker slice of Earth’s atmosphere than when it is overhead. Shorter blue wavelengths scatter away, leaving the longer red and orange wavelengths to reach your eyes. This is the same reason sunsets appear warm-toned. A Blood Moon during a lunar eclipse is a dramatic version of this — Earth’s atmosphere refracts reddish light directly onto the shadowed lunar surface.
