On May 31, 2026, a rare Sagittarius Blue Moon lights up the sky, and its effects will be felt by every sign. A Blue Moon occurs when two full moons rise within the same month, a phenomenon that happens only once every two and a half years. The last time the Sagittarius full moon was blue was May 31, 1988. We won’t see it again until 2044. Moments like this don’t come around twice.

Jupiter, the ruling planet of this lunation, brings with it an expansive wave of luck, higher thinking, and renewed possibility. Doors you thought were closed may swing open again, inviting you to reclaim what was lost and chase what still calls to you.
