What is the autumnal equinox

Equinoxes fall on the halfway point between solstices and occurs when the sun crosses the equator according to the Old Farmer's Almanac and day and night are each about 12 hours long .... The Sun crosses the celestial equator going southward it rises exactly due east and sets exactly due west.

The nearly equal 12 hours of light and darkness can be attributed to the Earth's lack of an axial tilt on the day of the equinox. In fact the word equinox is derived from the Latin words aequus meaning equal and nox meaning night.

In Johns Creek according to sunrisesunset.com the sun will come up at 7 26 a.m. and set at 7 34 p.m on the autumnal equinox. You'll notice that this is not actually a perfect 12 hours of light and darkness. As timeanddate.com reports that the disparity is because of issues such as light refraction and other reasons.
