A third quarter moon is when the moon has made it three quarters around the Earth during a lunar month (starting from new moon). The third quarter moon phase somes in between Full moon and New moon - meaning that it is a waning "half moon". A third quarter moon rises at midnight and sets around noon.
Either a First Quarter Moon or a Third Quarter Moon.
The third quarter moon appears as a half moon illuminated on the left side. It rises around midnight and sets around noon. This phase occurs when the moon is three-fourths of the way through its lunar cycle.
The phase of the moon that comes after the third quarter is the waning crescent. It appears as a small sliver of light on the left side of the moon.
The third quarter moon is when the moon is at a 90-degree angle from the sun, creating a half-lit moon with the right half visible. This phase occurs after the full moon and before the new moon in the lunar cycle.
First Quarter or Third Quarter.
First or Third Quarter
There are two phases of half moon, known as first quarter and third quarter. At first quarter, the Moon is one quarter of its journey around Earth, measured from new moon. If you look straight at a first quarter half moon, the Sun should be about 90° to your right, and you would see it in the evening. At third quarter, the Moon is three quarters of its journey around Earth, measured from new moon. If you look straight at a third quarter half moon, the Sun should be about 90° to your left , and you would see it in the early hours of the morning. We don't see that as often, as we are more likely to be in bed. If you look carefully and the conditions are right, you will see half moons during daylight.

Third Quarter is when the moon is half and is getting smaller.
At the moments of First Quarter and Third Quarter, the half-disk that you see is 50% of the "light side" ... half of the moon's illuminated surface. The entire moon is still there in the sky. The 'missing' half of the disk is comprised of half of the moon's dark side, which you can't see at that time. Because it's dark !

The amount of the lighted side of the moon you can see is the same during the first quarter and the last quarter phases. In both phases, half of the moon's illuminated side is visible from Earth.
Known as "First Quarter". The moon appears half-illuminated. If you are in the Northern Hemisphere, it is the half you see to your RIGHT. The moon rises in the east at roughly Noon, and sets in the west at roughly Midnight.
'Third Quarter' occurs 7.38 days after a Full Moon.After the Third Quarter, you'd have to wait 22.1 daysfor the next Full Moon.
