Short, factual guides to the Moon — dates, phases, eclipses, and how to choose a moon app. Written in the almanac voice: no horoscopes, no predictions.
Moon ephemeris — what the sky is about to do
The oldest page of any almanac is the one that looks forward. This one is computed the moment you open it, in your own time zone — the phases to come, the eclipses on their way, and the app's own rendezvous.
When is the next full moon?
The date and hour below are computed the moment you open this page, with the same astronomical algorithms as the Plenilune app — in your own time zone.
Full moon calendar 2026 — every date, with its name
Every full moon of 2026, computed with the reference astronomical algorithms — first shown in Universal Time, then in your own time zone once the page has loaded.
What is the moon phase today?
The reading below is computed the moment you open the page — same algorithms, same wording as the Plenilune app.

The whole cycle is a matter of geometry: the Sun always lights half of the Moon — what changes is how much of that lit half faces you.
Gardening by the Moon: the traditional calendar, explained
Lunar gardening is one of the oldest uses of the almanac. Here is what the tradition actually prescribes — told as tradition, with what the science says alongside.
A moon widget for your iPhone — home screen and lock screen

Lunar eclipses: the next dates, and why the Moon turns red
A lunar eclipse is the one night the phases lie: the full moon darkens, then glows copper-red. Here are the next dates — and the physics of that colour.
Why the Moon looks upside down in the southern hemisphere
Travellers notice it before they can explain it: from Sydney, the Moon of the postcards hangs the wrong way up. Nothing happened to the Moon — something happened to you.
