A lunar calendar is a calendar based on the monthly cycles of the Moon 's phases ( synodic months, lunations ), in contrast to solar calendars, whose annual cycles are based on the solar year.

The full moon is the lunar phase when the Moon appears fully illuminated from Earth 's perspective. This occurs when Earth is located between the Sun and the Moon (when the ecliptic longitudes of the Sun and Moon differ by 180° ). [3] This means that the lunar hemisphere facing Earth—the near side —is completely sunlit and appears as an ...
Lunar month. In lunar calendars, a lunar month is the time between two successive syzygies of the same type: new moons or full moons.

The exact times depend on the lunar phase and declination, as well as the observer's location. As viewed from outside the polar circles, the Moon, like all other celestial objects outside the circumpolar circle, rises ...
The use of astronomical symbols for the Sun and Moon dates to antiquity. The forms of the symbols that appear in the original papyrus texts of Greek horoscopes are a circle with one ray () for the Sun and a crescent for the Moon.

In December 1787, a luminous point was seen by a Maltese observer named d'Angos. On September 26, 1789, the German astronomer Johann Hieronymus Schröter noticed a speck of light close to the eastern foot of the Montes Alpes. It was seen on the night side of the Moon and appeared like a star of Magnitude 5 to the naked eye.
