What time of year does a equinox happen?

During an equinox, the sun is vertically above a point on the Earth's equator, so the earth's axis is not slanted away or towards the sun. An equinox occurs each year at two moments in time at a place where the center of the sun is above a point on the equator. They occur around March 20th or 21st and September 22nd or 23rd. On this day, the sun spends the same amount of time above and below the horizon for every place on earth, making day and night equally long.
