Moon phases in May 2028
In May 2028 the full moon falls on 8 May at 19:50 UTC, and the new moon on 24 May. 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.

May 2028 carries two first quarters. A lunar month is 29.53 days, so a long month occasionally holds the same phase twice.
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.
