AUTUMNAL EQUINOX FACTS
You often hear that days and nights are equal on the equinox. Except they’re not: There’s more minutes of sunshine than non-sun that day. That’s because the thick air near the horizon bends the sun’s image upward and gives each of us about six extra minutes of undeserved daily sunlight.
But those other equinox rumors are true. The sun really does rise and set precisely due east and due west that day. So it’s a good time to see how your home is aligned with the cardinal points of the compass. Or, to position your sundial, that task you’ve been postponing for so long.
Also, equinoxes are the only time when everyone on Earth, even those at each of the poles, see the sun shining. It’s a happy feel-good kind of thing even if it officially closes out our beloved summer season.( I got this information from this page: check this blog for more –http://www.almanac.com/blog/astronomy-blog/autumnal-equinox)
