Quizplus · Accepted Answer

On March 21 and September 22, the Sun rises exactly due east and sets exactly due west because these dates mark the spring and autumn equinoxes, respectively. During the equinoxes, the Earth's axis is tilted neither towards nor away from the Sun, resulting in equal day and night lengths all over the world.
