Full Moon calendar, with computed dates

A full Moon happens when the Moon sits directly opposite the Sun as seen from Earth, its whole visible face lit. Because the zodiac wheel places that opposition in a sign, every full Moon carries a sign: a Cancer full Moon always faces a Capricorn Sun, an Aquarius full Moon a Leo Sun, and so on around the year.

The sign changes the flavor astrologers give the moment: a full Moon in a water sign is often read as emotional high tide, one in an earth sign as a harvest check-in. Treat those readings as a reflective ritual rather than a forecast: the sky sets the scene, you write the story.

This page samples the positions of the Sun and the Moon day by day across the whole period and detects when their separation crosses 180 degrees (full Moon) or returns to 0 (new Moon). Dates are given to the day, sampled at noon UTC; depending on your time zone, the exact instant can fall a few hours into the neighboring day.
