What a Sagittarius Moon feels like
When the Moon moves through Sagittarius, the mood of the day tilts restless and searching. The Moon is the fastest body in the sky and she sets the emotional weather, so this is the undertone beneath September 18, 2026, changing again in a day or two as she moves on.
Her phase is the other half. This is a first quarter: a push and a decision point, act on what you started. If you are timing something that matters, the rule of thumb is to build on a waxing Moon, release on a waning one, and steer clear of the void-of-course windows above.
