Unlike a supermoon or lunar eclipse, a Black Moon isn't something you can watch unfold in real time. During the new moon phase, the moon is positioned between Earth and the sun, so its unlit side faces us, rendering it invisible against the bright sky.

The August 2025 new moon is special, even if we can't see it. This is a black moon. Here's what that means and how it may impact your sign. The new moon occurs on Aug. 22 at 11:06 p.m. PT and Aug. 23 at 2:06 a.m. ET. It comes down to timing. A black moon is the fourth new moon in a season that has had three full moons.
