The equinox occurs at the same moment worldwide.
The autumnal equinox—the September equinox or the fall equinox—arrives on Sunday, September 22.
Not only do temperatures drop, but plant life slows down, and so do we.
The autumnal equinox is an astronomical event that marks the start of autumn (or “fall”).
In the Northern Hemisphere, the autumnal equinox occurs in September; in the Southern Hemisphere, it occurs in March.
During an equinox, the Sun crosses what we call the “celestial equator”—an imaginary extension of Earth’s equator line into space.
The equinox occurs precisely when the Sun’s center passes through this line.
