The Sun is directly overhead the equator two times per year, known as the Equinoxes. In the northern hemisphere, the Spring Equinox occurs on March 20 and the Fall Equinox occurs on September 22.
That is known as the equinox, which occurs twice a year in spring and autumn. During the equinox, day and night are approximately equal in length all over the world.
During an equinox, the sun is directly over the equator of the Earth. This causes the length of day and night to be nearly equal all over the world.
The sun is directly over the southern hemisphere from the September equinox until the March equinox.
It's called the Equinox, which happens biannually, one called Vernal Equinox (Spring), and one called Autumnal Equinox (Fall).
An equinox is the moment when the Sun is directly over the Earth's equator, and the apparent position of the Sun at that moment. Daylight savings follows the equinox.
