Full Moon on . The illuminated surface of the moon is 100%. The lunar cycle is 15 days old.
* The exact date and time of this Full Moon phase is on 4 December 2025 at 23:14 UTC.
The moon rises at sunset and sets at sunrise. It is visible all night and it is high in the sky around midnight.

Main moon phases of the following lunar cycle.
Moon is passing about ∠21° of ♊ Gemini tropical zodiac sector.
The Full Moon these days is the Cold of December 2025.
There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.
Lunar disc appears visually 0.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1965" and ∠1947".
The Moon is 15 days old and navigating through the middle part of the current synodic month. This is lunation 320 of Meeus index or 1273 from Brown series.
The length of this lunation is 29 days, 18 hours and 56 minutes and it is 47 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2025. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 6 hours and 12 minutes longer than the mean synodic month length. It is 51 minutes shorter compared to 21st century's longest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠181.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠207°.
1 day since point of perigee on 4 December 2025 at 11:06 in ♊ Gemini the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next apogee on 17 December 2025 at 06:09 in ♏ Scorpio.
The Moon is 364 765 km (226 654 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 406 324 km (252 478 mi).
6 days after ascending node on 28 November 2025 at 21:33 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from North to South in descending node on 11 December 2025 at 07:35 in ♍ Virgo.
At 21:51 the Moon is meeting its standstill point to reach North declination of ∠28.263°. This is the year's northernmost lunar standstill of 2025. Over the upcoming 14 days the lunar orbit is going to tilt southward to face maximum declination of ∠-28.233° at the point of next southern standstill in ♐ Sagittarius on 19 December 2025 at 23:18.
6 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.
The Moon is in a Full Moon geocentric opposition with the Sun and thus forming Sun-Earth-Moon syzygy alignment.
