How to use the Moon phase calendar
Choose your city, or press Use my location, and enter a year. The result panel shows the current Moon over your place and the next four primary phases. The table below lists every lunation of the year, one row per cycle, with the date and local time of each new moon, first quarter, full moon and last quarter. The next phase is highlighted.
What the Moon’s numbers mean
- Illumination is the share of the Moon’s disc that is lit, from 0% at new moon to 100% at full moon. At first and last quarter it is 50%.
- Moon age is the number of days since the last new moon, from 0 to about 29.5.
- Distance from Earth varies between about 356,500 km at perigee and 406,700 km at apogee. A full moon near perigee is often called a supermoon and looks up to 14% larger than one near apogee.
Phases, eclipses and calendars
A solar eclipse can only happen at new moon and a lunar eclipse only at full moon, when the Sun, Earth and Moon line up closely enough; see the solar and lunar eclipses page for the next ones and whether you can see them. The Islamic calendar begins each month with the first sighting of the crescent after the new moon: see the Hijri calendar for its months.
To know when the Moon will actually be in your sky, use moonrise and moonset times. For the planets and bright stars around it, open the sky tonight.
