September 2026: Equinox, Harvest Moon, and a Busy Planetary Lineup

September 2026 delivers a busy astro calendar: Virgo-season helps organize after eclipse season, Libra season begins with the autumn equinox on Sept 22, and a Harvest Moon in Aries arrives Sept 26. Expect Venus in Scorpio sharpening intensity, Mercury changing signs and fueling sharp conversations, Uranus retrograde in Gemini, a mid-month Grand Air Trine boosting ideas, and Mars entering Leo toward month’s end, all urging clean slates, strategic action, and deeper self-reflection as fall begins.
