Equinox refers to two events that occur each year when the length of day and night are approximately equal all over the world. These events mark the formal beginning of the seasons of spring and autumn.
There are two equinoxes in a year:
1. Vernal Equinox or Spring Equinox: This occurs around March 20th or 21st in the Northern Hemisphere and September 22nd or 23rd in the Southern Hemisphere. During this equinox, the Sun is directly above the equator, resulting in equal lengths of day and night.
2. Autumnal Equinox: This occurs around September 22nd or 23rd in the Northern Hemisphere and March 20th or 21st in the Southern Hemisphere. During this equinox, the Sun is again directly above the equator, resulting in equal lengths of day and night.
The equinoxes are a result of the Earth's tilt on its axis as it orbits the Sun. They are significant as they mark the transition from one season to another and are often celebrated in various cultures and traditions around the world.
