Both the 1st Quarter moon and the 3rd (last) Quarter moon can be referred to as the "half moon" since we see half of the sunlit side of the moon.
A quarter moon, also known as a first or last quarter moon, appears as a half-circle or semicircle when viewed from Earth. During the first quarter, the right half is illuminated, while in the last quarter, the left half is lit. This shape results from the relative positions of the Earth, Moon, and Sun.
We see exactly half of the moon illuminated during the First Quarter and Last Quarter phases. In the First Quarter, the right half appears lit, while in the Last Quarter, the left half is illuminated. These phases occur approximately a week apart in the lunar cycle.
In the first quarter moon, the round portion of the visible moon faces west (forming the letter D when viewed in the northern hemisphere). In the last quarter phase the round portion faces west.
It is called "first quarter" or "last quarter" when the moon is exactly half-lit.
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 phases called "first quarter" and "third quarter" have those labels because theyoccur one quarter and three quarters of the period of time from one new moon untilthe next new moon.At both of those times, we see half of the moon lit up.
first or last quarter
In the first quarter moon, the round portion of the visible moon faces west (forming the letter D when viewed in the northern hemisphere). In the last quarter phase the round portion faces west.
During a quarter moon, the Sun, Earth, and Moon are positioned at a right angle to each other. This alignment occurs when the Moon is either in its first quarter or last quarter phase, with the Earth located between the Sun and the Moon in the case of the first quarter, and the Moon positioned between the Earth and the Sun during the last quarter. As a result, half of the Moon's surface facing Earth is illuminated, creating the distinct half-moon appearance.

The phase where the moon looks like a semicircle is called the "first quarter" or "last quarter," depending on its position in the lunar cycle. In the first quarter phase, half of the moon's surface is illuminated and visible from Earth, appearing as a right half. In the last quarter phase, the left half is illuminated. Both phases showcase a semi-circular appearance of the moon.
No, lunar phase refers to the illuminated portion of the Moon as seen from Earth, which changes continuously throughout the lunar cycle. A quarter moon specifically refers to the Moon when it is half-illuminated, representing either the first or last quarter of the lunar cycle.
