September 2025: Eclipses, Retrogrades & the Planetary Timeline

September 2025 is a compressed month astrologically. With eclipses, galactic alignments, and multiple outer planets retrograde, this is not a time for forcing outcomes. It is a month of review, reckoning, and recalibration — where the sky highlights pressure points that can no longer be ignored.

How to Work with September

Move slowly and deliberately. Use September to observe patterns, release what is clearly unsustainable, and simplify your structures — especially around health, work, communication, and resources. This month rewards honesty, nervous-system regulation, and conscious restraint more than bold new action.
