Now that all of the school supplies have been bought and kids are back in school, we start to notice a change in the weather as fall approaches.

Did you ever wonder exactly what the September equinox is? It’s happening today!

There are two equinoxes every year – in September and March – when the sun shines directly on the Equator and the length of day and night is nearly equal.

The September equinox occurs the moment the sun crosses the celestial equator – the imaginary line in the sky above the Earth’s Equator – from north to south. This happens either on September 22, 23, or 24 every year.

In the Northern Hemisphere, the September equinox marks the start of fall. Enjoy the next several weeks of apple picking and beautiful fall foliage!
