It's hard to believe that fall is just around the corner. Have no fear it really is literally on it's way. With it comes September Equinox. Fall is my favorite time of the year even though it's non stop preparations and celebrations I enjoy that part also.
There are two equinoxes every year ~ September and March. This is when the sun shines directly on the equator and the length of day and night is nearly equal.
Seasons are opposite each side of the equator, so the equinox in September is also known as the "autumnal (fall) equinox" in the northern hemisphere. But in the southern hemisphere, it's known as the "Spring (vernal) equinox".
On the equinox, night and day are nearly exactly the same length ~ 12 hours ~ all over the world. This is the reason it's called an "equinox" derived from Latin ("equal night"). September equinox occurs the moment the sun crosses the celestial equator ~ the imaginary line in the sky above the equator ~ from north to south.
So either on September 22, 23, or 24 every year. On any other day of the year, the Earth's axis tilts a little away from or towards the Sun.
In the northern hemisphere the September equinox marks the start of fall (autumn). Many cultures and religions celebrate or observe holidays and festivals around the September equinox.
