SAN ANGELO – Monday is the first official day of Spring.
In 2023, the spring equinox happens on March 20, at 5:24 P.M. EDT. This falls on a Monday and is the astronomical beginning of the spring season in the Northern Hemisphere and the autumn season in the Southern Hemisphere.
According to the Farmer's Almanac, the spring equinox in the Northern Hemisphere (also called the March equinox or vernal equinox across the globe) occurs when the Sun crosses the celestial equator going south to north. It’s called the “celestial” equator because it’s an imaginary line in the sky above the Earth’s equator.
Equinoxes are the only two times each year that the Sun rises due east and sets due west for all of us on Earth. While the Sun passes overhead, the tilt of the Earth is zero relative to the Sun, which means that Earth’s axis neither points toward nor away from the Sun.
The first day of summer will be June 21, 2023.
