A lunar phase or phase of the Moon refers to the appearance of the illuminated portion of the Moon as seen from Earth, which changes cyclically as the Moon orbits our planet. These phases result from the changing angles between the Earth, the Moon, and the Sun. The lunar phases are New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, and Waning Crescent. The cycle repeats approximately every 29.5 days, known as a synodic month. In Hebrew, the term is translated as מַשְׁקָף הַיָּרֵחַ (Mashkaf HaYareach). Other relevant translations include Mondphase in German, phase de la Lune in French, and fase lunar in Spanish. The lunar phases have been historically significant in various cultures for marking time, agricultural cycles, and religious observances.
