Full Moon on . The illuminated surface of the moon is 100%. The lunar cycle is 14 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 ∠6° 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 1.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1947".
The Moon is 14 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°.
Moon is at perigee at 11:06 about 14 days since last apogee on 20 November 2025 at 02:48 in ♏ Scorpio the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 12 days until point of next apogee on 17 December 2025 at 06:09 in ♏ Scorpio.
This perigee Moon is 356 962 km (221 806 mi) away from Earth. It is 5 546 km closer than the mean perigee distance, but it is still 13 394 km further than the closest perigee of 21st century.
5 days after ascending node on 28 November 2025 at 21:33 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from North to South in descending node on 11 December 2025 at 07:35 in ♍ Virgo.
11 days since the last southern standstill on 22 November 2025 at 18:12 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.295° the lunar orbit is extending northward over the next day to face maximum declination of ∠28.263° at the point of next northern standstill on 5 December 2025 at 21:51 in ♊ Gemini.
5 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.
