It's Almost the Official Start of Fall!
Dated: September 20 2021
This year, the autumnal equinox—also called the September equinox or fall equinox—arrives on Wednesday, September 22. This date marks the start of fall in the Northern Hemisphere and spring in the Southern Hemisphere.
Is the Day and Night equal during the equinox? Well, not exactly - it depends on where you live. On the equinox, the center of the Sun is indeed above the horizon for 12 hours. However, “sunrise” is said to begin when the upper edge of the Sun’s disk becomes visible above the horizon (which happens a bit before the center rises) and ends when the entire Sun has set. In this case, daylight is still a bit longer than nighttime.
Not only that, but the Sun is actually visible when it is below the horizon, as Earth’s atmosphere refracts the Sun’s rays and bends them in an arc over the horizon. Yes, you can see the Sun before the edge actually reaches the horizon! This causes daylight to be longer than 12 hours as well.
