What is the Spring Equinox?
The Spring Equinox, also known as the Vernal Equinox, is an astronomical event that marks the official beginning of spring in the Northern Hemisphere and autumn in the Southern Hemisphere. It is a significant date in the Earth’s calendar, as it is the moment when day and night are equal in length, and the sun crosses the celestial equator from north to south.
When is the Spring Equinox?
The Spring Equinox typically falls on March 20 or 21 in the Northern Hemisphere, and September 22 or 23 in the Southern Hemisphere. This date marks the moment when the sun reaches its maximum altitude in the sky, and the day and night lengths are equal. In the Northern Hemisphere, the sun rises due east at 3:38 AM and sets due west at 12:47 AM.
How does the Spring Equinox work?
The Spring Equinox marks the beginning of spring in the Northern Hemisphere because the Earth’s axis is tilted at an angle of 23.5 degrees relative to its orbital plane around the sun. This tilt causes the sun’s path across the sky to vary throughout the year, resulting in seasons. At the Spring Equinox, the sun’s path crosses the celestial equator, dividing the Earth into the Northern and Southern Hemispheres.
