Moon guides

The moon, month by month.

Phases, full moon dates and names, supermoons, and eclipses, calculated from the same astronomy that runs aluni.

How these dates are calculated

Every date and time on these pages comes from Jean Meeus's Astronomical Algorithms, a standard reference for amateur astronomers. Full moon times are accurate to a few minutes. Times are shown in UTC and switch to your time zone when your browser runs JavaScript.

Your sky, not just the calendar.

The sky above is the same everywhere, but what you can see depends on where you stand. aluni works out moonrise, moonset, and the best time to look tonight for your location, with the real hills and ridges around you.
