It is called "first quarter" or "last quarter" when the moon is exactly half-lit.
You can only see half of the moons lighting side
When the right half of the moon is illuminated it would be called first quarter. (That's when you see the Moon from the northern hemisphere.)

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.
The moon's so-called "quarter" phases occur a quarter of a month (i.e. a week) before and after the New Moon. On each of those occasions, the moon appears half-full.
That's the one called "First Quarter", taking place about 7.4 days after the New Moon.
This is the first quarter phase. The moon looks half lit, half in shadow, but you actually can only see one quarter of the moons surface at this point (during a full moon, you would only be able to see half of the moons surface - the half that faces us).

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.
