December 2026 Full Moon falls on Thursday, December 24, 2026.
December 2026 Full Moon falls on Thursday, December 24, 2026, which is 62 sleeps away. A sleep count is the number of nights still to come rather than the number of days, which is why it is the version adults reach for when the person asking is a child — and why it stays intuitive long after the day count stops meaning much.

How a sleep count works
The convention: one sleep means one night still to go. On the morning before, the answer is one. On the morning of the day itself, it is zero — you have run out of nights to sleep through. Because it tracks nights rather than 24-hour periods, the figure can read one higher than the day count for an event that lands in the morning.
About December 2026 Full Moon
The December 2026 full moon peaks at 01:30 UTC on December 24, 2026, at 2°14' Cancer in the tropical zodiac. Full moons always rise at sunset and set at sunrise, so the best viewing is any time the Moon is up that night — no equipment needed.
In astrology, the full moon in Cancer is considered the month's closing chapter: what began at the Cancer new moon six months earlier reaches fullness, and what is no longer working becomes impossible to ignore. Monthly full moons are the sky's built-in review meetings.
