You may have noticed the sun dipping below the horizon a little earlier recently. That’s because it’s nearly time for the autumnal equinox – sometimes called the September equinox – which occurs this year on the morning of Sept. 23. An equinox is when the sun appears directly over Earth's equator, resulting in nearly equal lengths of day and night. They only happen twice per year!
