On March 21, the vernal equinox occurs, marking the beginning of spring in the Northern Hemisphere. On this day, there are approximately 12 hours of daylight and 12 hours of darkness. This equal division of day and night is due to the position of the Earth in its orbit around the sun, where the tilt of the Earth's axis causes the sun to be directly above the equator.
