The Unseen Moon: What's a Black Moon?
WASHINGTON, USATuesday, December 31, 2024
So, what makes a black moon special? It's all about timing. A black moon happens every 29 months, making December 30, 2024, a fascinating day for sky-watchers. If you miss it, don't despair; the next one is scheduled for August 31, 2027.
Curiously, there's another type of black moon—when a season has four new moons instead of the usual three. Mark your calendars for August 23, 2025, for this unusual celestial treat.
Blue moons, on the other hand, are more common. They happen approximately every 2. 7 years. The next blue moon is coming up on May 31, 2026.
