Moon phases in January 2027
In January 2027 the full moon falls on 22 January at 12:18 UTC, and the new moon on 7 January. Every night of the month with its phase and how much of the Moon is lit, computed from the same engine the rest of the site runs on.
The exact moments
- New Moon
- First Quarter
- Full Moon
- Last Quarter
Times are UTC. A phase is a moment, not a night: the Moon is “full” at one instant, and looks full for a day either side of it. The live calendar works these out for your own clock and, if you let it, your own horizon.

Illumination is taken at 00:00 UTC on each date. It changes by a percent or two over a day, which is why the site’s own nightly card computes it for the evening you are actually standing in.
