About September Equinox
The September Equinox brings day and night back into near balance and marks the start of astronomical fall in the Northern Hemisphere. Leaves begin changing color, temperatures ease down, and many places shift into harvest and back-to-school rhythm. In the Southern Hemisphere, this same moment marks the start of spring.
