At new moon the Moon passes between Earth and the Sun, so the side facing us is unlit and it is invisible. These are the darkest nights of the month and the best ones for stargazing.

How the date is worked out

New moons follow the same 29.5-day lunar month as full moons, falling exactly half a cycle apart from them.
