Day and night are of equal length at the Spring and Fall equinoxes, when the tilt of the earth's axis is in the direction of the orbital track, as opposed to the Summer and Winter solstices when the tilt is directly toward or away from the Sun.

∙ 14y agoIt's called an equinox. At this time, the sun is vertically above a point on the Earth's equator, so the earth's axis is not tilted 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. It occurs around March 20th or 21st and September 22nd or 23rd. On this day, the sun spends equal time above and below the horizon for every place on earth, making day and night equally long.
