The cycle of changes in the amount of the moon that appears lit as seen from Earth is called the lunar phases. It is caused by the relative positions of the Earth, Moon, and Sun, resulting in the Moon's illuminated portion varying from no visible light (new moon) to fully illuminated (full moon) and back again. This cycle repeats approximately every 29.5 days.
The lunar cycle of phases is about 29.5 days. As the moon rotates and revolves around the earth, and the earth rotates and revolves around the sun, the shadows cast by the shifting positions of the moon and earth cause the moon to wane, wax, and "disappear". This is known as the lunar cycle.
Our calanders are based on the time taken for the earth to orbit the sun (1 year) and the time taken for the earth to spin once on it's axis (1 day). The phases of the moon, or the moon orbiting the earth, doesn't really come into it, but it takes around 29 days for the moon to orbit us.
The complete cycle of moon phases repeats every 29.53 days.
Half of the Moon you cannot see because it faces away from Earth. Half of the side you could see is in darkness at "half Moon". That makes 3/4 of the Moon invisible and 1/4 visible. Hence "a quarter Moon" is visible. Another viewpoint: No, that's not really the answer. This is the answer: Let's start with "New Moon". Later, at "Full Moon", the Moon is halfway through its cycle of phases. Halfway between these two phases we see a half Moon. That's called the "first quarter" phase, because the Moon is a quarter of the way through its phases. So, that's why we see the half Moon at a "quarter" phase. It does cause confusion.

The daily changes of the moon's appearance are called moon phases. This cycle is caused by the changing positions of the Earth, moon, and sun, resulting in varying amounts of sunlight reaching the moon's surface.

The cause of the phases of the Moon is closely related to our calendar month. (moon-th). The phases of the Moon are related to the Moon's orbit of Earth.

The cycle of changes in the amounts of the moon that appears lit is called the lunar phases. This cycle lasts about 29.5 days and includes eight distinct phases: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent. These phases result from the relative positions of the Earth, moon, and sun, affecting how much of the moon's surface is illuminated as observed from Earth.
One complete cycle of the moon's phases, from new moon to full moon and back to new moon, takes about 29.5 days. This period is known as a lunar cycle or a synodic month.
The four main phases of the lunar cycle are the New Moon (which is not visible except during an eclipse), First Quarter (waxing half moon), Full Moon (all of which is visible) and Third Quarter (waning half moon). The moon phases in between the four main phases are the crescent and gibbous phases.
Our calanders are based on the time taken for the earth to orbit the sun (1 year) and the time taken for the earth to spin once on it's axis (1 day). The phases of the moon, or the moon orbiting the earth, doesn't really come into it, but it takes around 29 days for the moon to orbit us.
