The seasonal timepost of the autumnal equinox will occur at 9:49 a.m. Saturday, according to EarthSky.org.
This is the day where the Earth doesn't tilt away or toward the sun, setting Earthlings up for when days begin to get shorter and shorter.
The vernal equinox is in March.
The equinox has many myths surrounding it, including being able to balance an egg on its fat end only on these days. But, as Snopes.com reported, this can actually happen any day of the year. See attached video for someone balancing an egg during the equinox.
