Equinox

The equinox is an event that happens twice a year due to the 22 degree angle of the Earth and its revolution pattern. The equator gets 12 hours of day and 12 hours of night every day because it is always facing the sun directly. Only two days of the year though, the rest of the Earth gets the same amount of light. Rotation of the Earth also has a certain amount to do with it, that being the day and night part. During the equinox, the Earth's tilt is facing lateral compared to the sun, which ultimately causes this change in amount of light.
