Choose a day to see its moonrise, moonset and the Moon's age.
Drawn as seen from the Northern Hemisphere: a waxing Moon is lit on the right.
Each square shows the Moon at local noon for the place you choose, with the lit part in silver and the percentage of the disc that is lit. A day is labelled New Moon, First Quarter, Full Moon or Last Quarter when that exact moment falls on it in your time zone, and the time is shown in the square. Choose any day to see its moonrise, moonset and the Moon's age in days since the last new moon. Move with the arrows or the month and year boxes; Print this month gives a one-page landscape copy, and the CSV has every day's figures for a spreadsheet.
A phase happens at the same instant everywhere, but the date it lands on depends on your time zone: the Hunter's Moon of 26 October 2026 (04:12 UTC) is still the evening of the 25th in Los Angeles. The picture changes too. Seen from the Southern Hemisphere the Moon is upside down compared with the view from the north, so a waxing Moon is lit on the left. The calendar flips its drawings for southern places automatically; close to the equator a crescent lies tipped on its back, more like a bowl.
Positions of the Sun and Moon follow Jean Meeus's Astronomical Algorithms and are worked out in your browser. Phase times match the US Naval Observatory's published 2026 times to within a minute, and the percentage lit is measured at local noon, as in the Naval Observatory's tables.
