New Moon on . The illuminated surface of the Moon is 0%. Lunar cycle is 1 day young.
* The exact date and time of this New Moon phase is on 20 December 2025 at 01:43 UTC.
The moon rises at sunrise and sets at sunset. It's part facing the Earth is completely in shadow.

Main moon phases of the following lunar cycle.
Moon is passing about ∠22° of ♐ Sagittarius tropical zodiac sector.
Next Full Moon is the Wolf Moon of January 2026 after 14 days on 3 January 2026 at 10:03.
There is high New Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Moon-Earth syzygy alignment.
Lunar disc is not visible from Earth. Moon and Sun apparent angular diameters are ∠1775" and ∠1950".
At 06:47 on this date the Moon completes the old and enters a new synodic month with lunation 320 of Meeus index or lunation 1273 from Brown series.
The length of the lunation is 29 days, 18 hours and 56 minutes. This is the year's longest synodic month of 2025. It is 47 minutes longer than the next lunation's length. 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 is ∠181.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠207°.
2 days since point of apogee on 17 December 2025 at 06:09 in ♏ Scorpio the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 13 days until the Moon reaches the point of next perigee on 1 January 2026 at 21:43 in ♊ Gemini.
The Moon is 403 858 km (250 946 mi) away from Earth and getting closer over the next 13 days until the point perigee when Earth-Moon distance is going to be 360 348 km (223 910 mi).
8 days after descending node on 11 December 2025 at 07:35 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from South to North in ascending node on 25 December 2025 at 22:03 in ♓ Pisces.
At 23:18 the Moon is meeting its standstill point to reach South declination of ∠-28.233°. This is the year's southernmost lunar standstill of 2025. Over the upcoming 13 days the lunar orbit is going to tilt northward to face maximum declination of ∠28.265° at the point of next northern standstill in ♊ Gemini on 2 January 2026 at 08:20.
20 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.
The Moon is in a New Moon geocentric conjunction with the Sun and thus forming Sun-Moon-Earth syzygy alignment.
