There are eight generally accepted names for the phases of the Moon, but in reality the moon's phase is a little different every night - in fact, every hour.
Beginning with the New Moon, the phases are
Waxing crescent
First Quarter
Waxing gibbous
Full
Waning gibbous
Third quarter
Waning crescent
There are only 8 phases of the moon.
It takes about 28-30 days.

The phases of the Moon are a result of its position relative to the Sun and Earth. As the Moon orbits the Earth, different portions of its illuminated side are visible from Earth, creating the different phases we observe.
The moon rotates around the earth while earth rotates around the sun. The moon's lighted side always points to the sun. The moon's revolution affects this because as the moon revolves it shows different sides t the earth.
8 phases.
I believe that if a planet makes one revolution, such as the Earth or Moon, it has completed its orbit once.
Phases of the moon are caused by the revolution of the moon around the Earth and the revolution of the Earth around the sun. As long as the moon revolves around the Earth as it does, the lunar cycle from full to new to full again will take about 29½ days. We will be having about twelve and a third moon cycles every year until these facts change.

When the moon has completed half of its revolution around the Earth, it is referred to as the "First Quarter" or "Last Quarter," depending on its position in relation to the Earth and the Sun. In the First Quarter phase, the right half of the moon is illuminated, while in the Last Quarter, the left half is lit up. These phases occur approximately one week apart in the lunar cycle.
The stages of the Moon, are referred to as the 'Phases of the Moon'.
