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 23 January 2031 at 04:31 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 ∠8° of ♒ Aquarius tropical zodiac sector.
Next Full Moon is the Snow Moon of February 2031 after 15 days on 7 February 2031 at 12:46.
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 ∠1949" and ∠1949".
At 04:31 on this date the Moon completes the old and enters a new synodic month with lunation 384 of Meeus index or lunation 1337 from Brown series.
The length of the lunation is 29 days, 11 hours and 18 minutes. It is 42 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 1 hour and 26 minutes shorter than the mean synodic month length. It is 4 hours and 43 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit is ∠21.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠41.9°.
1 day since point of perigee on 21 January 2031 at 21:41 in ♑ Capricorn the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next apogee on 2 February 2031 at 23:45 in ♊ Gemini.
The Moon is 367 800 km (228 540 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 405 416 km (251 914 mi).
4 days after ascending node on 19 January 2031 at 08:51 in ♐ Sagittarius the Moon is positioned north of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from North to South in descending node on 1 February 2031 at 09:25 in ♊ Gemini.
3 days since the last southern standstill on 20 January 2031 at 05:10 in ♐ Sagittarius when the Moon has reached South declination of ∠-21.824° the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠21.745° at the point of next northern standstill on 2 February 2031 at 12:52 in ♊ Gemini.
4 days since the beginning of this draconic month in ♐ Sagittarius 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.
