"New moon In astronomy, the new moon is the first lunar phase, when the Moon and Sun have the same ecliptic longitude. At this phase, the lunar disk is not visible to the unaided eye, except when silhouetted during a solar eclipse. Daylight outshines the earthlight that dimly illuminates the new moon. The actual phase is usually a very thin crescent. The original meaning of the term ""new moon"", which is still sometimes used in non-astronomical contexts, was the first visible crescent of the Moon, after conjunction with the Sun. This crescent moon is briefly visible when low above the"

Chinese scholars have variously interpreted these two terms as lunar quarters or fixed days, and (Shaughnessy 1992:136–145) Wang Guowei's lunar-quarter analysis the most likely. Thus, ""jishengpo"" is from the 7th/8th to the 14th/15th days of the lunar month and ""jisipo"" is from the 23rd/24th to the end of the month.

The lunar crescent can open upward or downward, with the ""horns"" of the crescent pointing up or down, respectively.

"The eleventh crescent, with the bulge, is where one of those nights is found in Thomson's and Métraux's records. Guy notes that the further the Moon is from the Earth in its eccentric orbit, the slower it moves, and the more likely the need to resort to an intercalary night to keep the calendar in sync with its phases. He hypothesizes that the ""heralding sequences"" are instructions to observe the apparent diameter of the Moon, and that the half-size superscripted crescents (orange) preceding the sixth night before and sixth night after the full moon represent the small apparent diameter at"
"misnomer.) In western culture, the four ""principal phases"" of the Moon are new moon, first quarter, full moon, and third quarter (also known as last quarter). These are the instances when the Moon's ecliptic longitude and the Sun's ecliptic longitude differ by 0°, 90°, 180°, and 270°, respectively. Each of these phases occur at slightly different times when viewed from different points on Earth. During the intervals between principal phases, the Moon's apparent shape is either crescent or gibbous. These shapes, and the periods when the Moon shows them, are called the ""intermediate phases"" and last one-quarter of a synodic"

When used to represent a waxing or waning lunar phase, ""crescent"" or ""increscent"" refers to the waxing first quarter, while the symbol representing the waning final quarter is called ""decrescent"". The crescent symbol was long used as a symbol of the Moon in astrology, and by extension of Silver (as the corresponding metal) in alchemy. The astrological use of the symbol is attested in early Greek papyri containing horoscopes. In the 2nd-century"

A date under this scheme might be ""the third (day) of Thargelion waning"", meaning the 28th day of Thargelion. To summarise the days with special names. This strange juxtapositioning of the two days called the tenth, the earlier and the later, further highlighted the shift into the moon's waning phase.

Earthshine is most clearly seen after dusk during the waxing crescent (in the western sky) and before dawn during the waning crescent (in the eastern sky). The term ""earthlight"" would also be suitable for an observer on the Moon seeing Earth during the lunar night, or for an astronaut inside a spacecraft looking out the window. Arthur C.

"Lunar phase The lunar phase or phase of the Moon is the shape of the directly sunlit portion of the Moon as viewed from Earth. The lunar phases gradually and cyclically change over the period of a synodic month (about 29.53 days), as the orbital positions of the Moon around Earth and of Earth around the Sun shift. The Moon's rotation is tidally locked by Earth's gravity; therefore, most of the same lunar side always faces Earth. This near side is variously sunlit, depending on the position of the Moon in its orbit. Thus, the sunlit portion of this face"

The crescent Moon is most clearly and brightly visible when the Sun is below the horizon, which implies that the Moon must be above the Sun, and the crescent must open upward. This is therefore the orientation in which the crescent Moon is most often seen from the tropics. The waxing and waning crescents look very similar. The waxing crescent appears in the western sky in the evening, and the waning crescent in the eastern sky in the morning.

The classical crescent shape has its horns pointing upward (and is often worn as horns when worn as a crown or diadem, e.g. in depictions of the lunar goddess, or in the headdress of Persian kings, etc. The word ""crescent"" is derived etymologically from the present participle of the Latin verb """" ""to grow"", technically denoting the waxing moon ().

"Phases of Venus The phases of Venus are the different variations of lighting seen on the planet's surface, similar to lunar phases. The first recorded observations of them were telescopic observations by Galileo Galilei in 1610. Although the extreme crescent phase of Venus has been observed with the naked eye, there are no indisputable historical pre-telescopic records of it being observed. The phases of Venus result from the planet's orbit around the Sun inside the Earth's orbit giving the telescopic observer a sequence of progressive lighting similar in appearance to the moon's phases. It presents a ""full"" image when it"

When a crescent moon occurs, the phenomenon of earthshine may be apparent, where the night side of the Moon dimly reflects indirect sunlight reflected from Earth. In the Northern Hemisphere, if the left (east) side of the Moon is dark, then the bright part is thickening, and the Moon is described as waxing (shifting toward full moon). If the right (west) side of the Moon is dark,"
"lunar eclipses: penumbral, when the Moon crosses only the Earth's penumbra; partial, when the Moon crosses partially into the Earth's umbra; and total, when the Moon crosses entirely into the Earth's umbra. Total lunar eclipses pass through all three phases. Even during a total lunar eclipse, however, the Moon is not completely dark. Sunlight refracted through the Earth's atmosphere enters the umbra and provides a faint illumination. Much as in a sunset, the atmosphere tends to more strongly scatter light with shorter wavelengths, so the illumination of the Moon by refracted light has a red hue, thus the phrase 'Blood"

Venus presents a ""thin crescent"" in telescopic views as it comes around to the near side between the Earth and the Sun and presents its ""new phase"" when it is between the Earth and the Sun.

The brightness of a full moon as compared to a phase where a smaller percentage of the surface is illuminated tends to wash out substantial amounts of detail and can actually leave an afterimage on an observer's eye that can persist for several minutes. First quarter (six to nine days past new moon) is generally considered the best time to observe the Moon for the average stargazer. Shadows and detail are most pronounced"

"Crescent A crescent shape (, British English also ) is a symbol or emblem used to represent the lunar phase in the first quarter (the ""sickle moon""), or by extension a symbol representing the Moon itself. It is used as the astrological symbol for the Moon, and hence as the alchemical symbol for silver. It was also the emblem of Diana/Artemis, and hence represented virginity. In Roman Catholic Marian veneration, it is associated with the Virgin Mary. From its use as roof finial in Ottoman era mosques, it has also become associated with Islam, and the crescent was introduced as"

Its representation with the horns pointing sideways (as a heraldic ""crescent increscent"" or ""crescent decrescent"") is early modern. The same symbol can be used in a different context not for the Moon itself but for a lunar phase, as part of a sequence of four symbols for ""new moon"" (U+1F311 🌑), ""waxing"" (U+263D ☽), ""full moon"" (U+1F315"

When the ascending node of the lunar orbit is in the vernal equinox, the lunar declination can reach up to plus or minus 28° each month. This means the Moon can pass overhead if viewed from latitudes up to 28° north or south (of the Equator), instead of only 18°. The orientation of the Moon's crescent also depends on the latitude of the viewing location; an observer in the tropics can see a smile-shaped crescent Moon."

When moonrise precedes midnight one night, the next moonrise will follow midnight on the next night (so too with moonset).
