New Moon PhaseW
hat is a new moon
? The astronomical new moon
, sometimes known as the dark moon
to avoid confusion, occurs by definition at the moment of conjunction in ecliptic longitude with the Sun, when the Moon is invisible from the Earth. This means that the Sun and Earth are on the opposite sides of the Moon, and only the dark side of the moon faces the Earth. This moment is unique and does not depend on location, and in certain circumstances it coincides with a solar eclipse. Each new lunar cycle is measured beginning at each new moon
New Moon Dates / Next New Moon
When is the next new moon? The average calendrical month, which is 1/12 of a year, is about 30.44 days, while the Moon’s phase (synodic) cycle repeats on average every 29.53 days. Therefore the timing of the Moon’s phases shifts by an average of almost one day for each successive month. To find out the new moon dates, please see the new moon calendar below.
New Moon and The Moon Phases
The new moon occurs when the moon is positioned between the Earth and the Sun. The three objects are in approximate alignment. The entire illuminated portion of the moon is on the back side of the moon, the half that we cannot see.
Each lunar cycle begins with a new moon. As the Moon moves eastward away from the Sun in the sky, we see a bit more of the sunlit side of the Moon each night. We call this waxing. After the new moon, the sunlit portion is increasing, but less than half illuminated, so it is a waxing crescent moon. When half of the Moon’s disc is illuminated, we call it the first quarter moon. As the sunlit portion continues to increase, now more than half illuminated, it becomes waxing gibbous moon. When the Moon reaches maximum illumination, a full moon, the Moon has completed one half of the lunar month.
During the second half of the lunar month, the Moon grows thinner each night. We call this waning. The waning gibbous moon phase occurs first, followed by the last quarter moon when half of the Moon’s disc is illuminated. Next is the waning crescent moon, which wanes until the illumination is completely gone; a new moon.
New Moon Calendar 2019
The new moon calendar for 2019 is expressed in Coordinated Universal Time (UT), the international basis for other time zones. At the time of the new moon, the moon rises at about the same time the sun rises, and it sets at about the same time the sun sets. Astronomers call one lunar cycle a lunation. For new moon times in your city, please use the Time Zone Converter. You may also simply subtract five (5) hours to get to U.S. Eastern Time.
New Moon Solar Eclipse
Sometimes, if the Moon lies directly between the Earth and the Sun during the new moon phase, a solar eclipse occurs as the Earth enters the Moon’s shadow. In most locations on Earth, only a fraction of the Sun will be obscured, in a partial solar eclipse. Locations where the center of the shadow passes over experience a total eclipse in which the Moon completely obscures the Sun, or an annular or ring eclipse, in which the apparent size of the Moon is smaller than the Sun.
New Moon Original Meaning
The original meaning of the phrase “new moon” was the first visible crescent of the Moon, after conjunction with the Sun. This takes place over the western horizon in a brief period between sunset and moonset, and therefore the precise time and even the date of the appearance of the new moon by this definition will be influenced by the geographical location of the observer.
