While the exact moment of the equinox can fall on the 22nd or the 23rd depending on the year and time zone, the spirit of balance and change is a hallmark of the period around September 23, 2025. It’s a natural time for reflection, seasonal celebration, and a renewed connection to the cycles of nature.
