Equinox, Vernal: March 20
The vernal equinox, also known as the spring equinox, occurs when the center of the sun is directly above the Earth’s equator. This happens twice a year, once in the spring and once in the fall. The spring equinox is the point in time when the Earth’s axis is tilted neither towards nor away from the sun, resulting in nearly equal lengths of day and night all over the world. This phenomenon is due to the Earth’s orbit around the sun being tilted at an angle of approximately 23.5 degrees.
During the vernal equinox, the sun rises and sets exactly due east and west, respectively. The duration of daylight is approximately 12 hours, and the duration of darkness is also approximately 12 hours.
The vernal equinox is a significant astronomical event that marks the beginning of spring in the Northern Hemisphere and the beginning of autumn in the Southern Hemisphere. In many cultures around the world, the vernal equinox is celebrated with festivals and rituals to mark the changing of the seasons.
