When shines half the moon?

Question

When shines half the moon?

Answer 1

There is no phase called a "half moon".  Half of the Moon is nearly always lit up by the Sun.  But we can see the entire half that is lit up at Full Moon.

Answer 2

Except during times of lunar eclipses, half of the Moon is illuminated by the Sun, and the other half is in darkness.  We see different portions of the illuminated Moon as it rotates in its orbit around the Earth every 29.5 days.
