New Moon on . The illuminated surface of the Moon is 0%. Lunar cycle is less than 1 day young.
* The exact date and time of this New Moon phase is on 14 December 2031 at 09:06 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 ∠24° of ♐ Sagittarius tropical zodiac sector.
Next Full Moon is the Cold Moon of December 2031 after 14 days on 28 December 2031 at 17:33.
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 ∠1950" and ∠1949".
At 09:06 on this date the Moon completes the old and enters a new synodic month with lunation 395 of Meeus index or lunation 1348 from Brown series.
The length of the lunation is 29 days, 11 hours and 1 minute. This is the year's shortest synodic month of 2031. It is 43 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 1 hour and 43 minutes shorter than the mean synodic month length. It is 4 hours and 26 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit is ∠334.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠351.6°.
10 days since point of apogee on 3 December 2031 at 22:35 in ♌ Leo the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 15 December 2031 at 21:31 in ♑ Capricorn.
The Moon is 367 588 km (228 409 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 360 489 km (223 997 mi).
2 days after ascending node on 12 December 2031 at 01:37 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from North to South in descending node on 24 December 2031 at 18:44 in ♉ Taurus.
At 04:45 the Moon is meeting its standstill point to reach South declination of ∠-20.356°. Over the upcoming 12 days the lunar orbit is going to tilt northward to face maximum declination of ∠20.355° at the point of next northern standstill in ♊ Gemini on 27 December 2031 at 07:41.
2 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the beginning to the first 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.
