This page uses a live countdown and updates every second.
A full moon happens about every 29.5 days. This period is called a synodic lunar month. Because calendar months are different lengths, some months can contain two full moons.
A full moon happens when the Moon is opposite the Sun from Earth, so the side facing us is fully illuminated. The full moon is not only a beautiful night-sky event; it is also the center point of the lunar month and a useful marker for calendars, tides, festivals, photography, farming traditions and astronomy planning.
The Moon does not make its own light. The side we see is illuminated by the Sun, and as the Moon moves around Earth we see different amounts of its sunlit half. These changing shapes are the phases of the moon: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter and waning crescent. The full moon and the gibbous phase on either side of it are the brightest part of the cycle, while the crescent and quarter steps show how far the lunar phases have moved through the month.
The full moon happens at one exact moment worldwide, but your calendar date depends on local time. For example, a full moon that occurs late at night in UTC may already be the next morning in Asia or Australia, while it may still be the previous day in the Americas.
That is why FullMoonCountdown.com shows both the local countdown and the UTC time. This helps you avoid confusion when comparing moon calendars from different countries.
Traditional full moon names are useful for search, culture and skywatching. The exact names can vary by region, but these are the most widely used English names.
A blue moon usually means the second full moon in the same calendar month. This happens because the lunar cycle is about 29.5 days, while most calendar months are 30 or 31 days. A blue moon is not normally blue in color; the name is about timing.
Read the blue moon guide or check monthly full moon pages to see when a month contains two full moons.
A supermoon happens when a full moon occurs near the Moon's closest point to Earth, called perigee. It can look slightly larger and brighter than an average full moon, especially when it rises near the horizon.

Most years have 12 full moons, but some years have 13 when one calendar month contains two full moons.
A full moon rises around sunset and sets around sunrise, so it is usually visible for most of the night if the sky is clear.
Yes. Full moons and new moons are linked with spring tides, when the Sun, Earth and Moon line up and tidal ranges are often stronger.
The best time is often near moonrise or moonset, when the Moon is close to the horizon and easier to frame with buildings, trees or landscapes.
