The Autumnal Equinox is observed annually when the sun can be seen directly overhead along the equator, marking the end of summer and beginning of fall in the Northern Hemisphere.
The autumn equinox is one of two days when all points on Earth except the polar regions see the sun rise and set at due east and due west. With few exceptions, all latitudes see almost exactly 12 hours of daylight and 12 of dark.
Seasons are opposite on either side of the Equator, so the equinox in September is also known as the Autumnal (fall) equinox in the Northern Hemisphere. In the Southern Hemisphee, it's known as the Vernal (spring) equinox.

Sun Crosses Celestial Equator
The September equinox occurs the moment the Sun crosses the celestial equator – the imaginary line in the sky above Earth’s Equator – from north to south.
On any other day of the year, either the southern hemisphere or the Northern Hemisphere tilts a little towards the Sun. But on the two equinoxes, the tilt of Earth's axis is perpendicular to the Sun's rays, like the illustrations show.
Earth orbits the Sun at a slant, which is why equinoxes and solstices happen
