New Moon on . The illuminated surface of the Moon is 1%. Lunar cycle is 1 day young.
* The exact date and time of this New Moon phase is on 21 May 2031 at 07:17 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 ∠20° of ♉ Taurus tropical zodiac sector.
Next Full Moon is the Strawberry Moon of June 2031 after 15 days on 5 June 2031 at 11:58.
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 ∠1804" and ∠1896".
At 16:57 on this date the Moon completes the old and enters a new synodic month with lunation 387 of Meeus index or lunation 1340 from Brown series.
The length of the lunation is 29 days, 14 hours and 20 minutes. It is 47 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 36 minutes longer than the mean synodic month length. It is 5 hours and 27 minutes shorter compared to 21st century's longest synodic month length.
The true anomaly of the Moon orbit is ∠106.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠139.8°.
11 days since point of perigee on 9 May 2031 at 07:28 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 4 days until the Moon reaches the point of next apogee on 25 May 2031 at 02:08 in ♋ Cancer.
The Moon is 397 284 km (246 861 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 405 723 km (252 105 mi).
12 days after ascending node on 7 May 2031 at 22:55 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 21 May 2031 at 03:26 in ♉ Taurus.
11 days since the last southern standstill on 9 May 2031 at 07:56 in ♐ Sagittarius when the Moon has reached South declination of ∠-21.092° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠21.091° at the point of next northern standstill on 22 May 2031 at 19:41 in ♊ Gemini.
12 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.
