Today is the first day of FALL in the Northern Hemisphere
Twice a year, everyone on Earth is seemingly on equal footing -- at least when it comes to the distribution of light and dark.
On Wednesday, September 22, we enter our second and final equinox of 2021. If you reside in the Northern Hemisphere, you know it as the fall equinox (or autumnal equinox). For people south of the equator, this equinox actually signals the coming of spring.
Folks really close to the equator have roughly 12-hour days and 12-hour nights all year long, so they won't really notice a thing. But people close to the poles, in destinations such as the northern parts of Canada, Norway and Russia, go through wild swings in the day/night ratio each year. They have long, dark winters and then have summers where night barely intrudes.
There's a good explanation (SCIENCE!) for why you don't get precisely 12 hours of daylight on the equinox. More on that farther down in the article.
