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

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.

In Japan, Autumnal Equinox Day is a national holiday. In Japanese, it’s known as Shubun no Hi (秋分の日), according to Coto Japanese Academy. The roots of the celebration are thought to go back to Shintoism and Buddhism.
