There are two kinds; the vernal equinox when the Sun passes over the equator heading toward you, or the autumnal equinox when the Sun passes over the equator going away from you.
If you live in the northern hemisphere - North America, Asia, Europe - the vernal (or spring ) equinox is around March 21. If you are in the Southern Hemisphere - most of Africa and south America, and all of Australia - the vernal equinox is around September 21. Each of these dates can shift one or two days either way depending on the cycle of leap years.
