"Equinox" can refer to a few different concepts depending on the context: 1. **Astronomy**: An equinox is an astronomical event that occurs twice a year when the sun is directly above the equator, resulting in nearly equal lengths of day and night across the globe. The two equinoxes are the vernal (spring) equinox, occurring around March 20 or 21, and the autumnal equinox, occurring around September 22 or 23.
