Moon phases

When this page was built, on Wed 28 Oct 2026, the Moon was waning gibbous, 93% lit.

Full Moons, the year ahead

Each full Moon by the name North American almanacs give it. The Harvest Moon is the full Moon nearest the September equinox, and a Blue Moon the second full Moon in a calendar month. Each name opens its month’s page: when it rises and sets, and how much of the night it is up, at each latitude.

Every phase, the year ahead

One row for each turn of the Moon, from new Moon to new Moon, in UTC. Each date opens the map on the Moon at that minute.

In your own calendar

The same phases, with eclipses, meteor showers and the planets, as a calendar that keeps itself up to date.

How it is worked out: the instant the Moon’s ecliptic longitude stands 0°, 90°, 180° and 270° east of the Sun’s, from Meeus’s lunar theory, the same one the map draws the Moon by, checked against the U.S. Naval Observatory’s times and JPL Horizons. A supermoon is a full Moon nearer than 360,000 km; eclipses are held to NASA’s canon. Times are found when the site is built, and the dates and months here are UTC’s: a full Moon early on the 1st can be the last day of the month before west of Greenwich. The method and its measured error.
