The autumnal equinox falls on Saturday, September 22, 2018. Here’s everything you need to know about the equinox, as well as a few frequently asked questions and signs of the equinox in nature. The Northern Hemisphere marks the autumnal equinox on Saturday, September 22, 2018, at exactly 9:54 P.M. EDT. During the equinox, the Sun crosses what we call the “celestial equator” (just imagine the line that marks the equator on Earth extending up into the sky) from north to south. Because of this, Earth’s two hemispheres receive the Sun’s rays about equally. The Sun is overhead at noon as seen from the equator, so at this point, the amount of nighttime and daytime (sunlight) are roughly equal to each other.
