Fall is in the air—officially. The September equinox marks the transition from summer to autumn in the Northern Hemisphere, while in the Southern Hemisphere, spring is just beginning. The term "equinox," derived from Latin, means "equal night." It marks one of two points during the year when the sun sits directly over the equator, and the Earth receives roughly equal amounts of daylight and darkness.
