It's almost time to fall into fall, though in many parts of the country, it feels like we're already there. There are specific times when the astronomical seasons officially turn over -- for fall, it's the autumnal equinox.

During an equinox, places around the globe experience nearly equal amounts of daytime and nighttime. The second occurrence this year happens on Sunday.

Twice a year, the sun doesn’t play favorites. Everyone on Earth is seemingly on equal status – at least when it comes to the amount of light and dark that they get.
