In simple terms, “waning” means decreasing, and “gibbous” describes a shape that’s more than half full but not quite complete. So, a waning gibbous moon is when the moon is more than 50% illuminated but getting less so each night. It rises later in the evening, often appearing in the late-night or early-morning sky. This phase lasts for about a week, offering a perfect window for contemplation.
Visually, it’s the opposite of the waxing gibbous, which grows toward the full moon. The waning gibbous is like the moon’s unwinding, a slow fade from brilliance to shadow. You’ll notice it in the eastern sky after sunset, or high overhead just before dawn. It’s a quiet, steady presence—perfect for night owls and early risers alike.
