Spring Finally Arrives at 11:57am CDT Today
Today marks the first day of spring or the day that the Vernal Equinox occurs. After the long winter we just endured, it couldn't come soon enough. The word Vernal means “occurring in spring” and the word Equinox means “equal night”.
So in essence, days and nights are approximately equal everywhere and the Sun rises and sets due east and west.
Of course when spring arrives in the Northern Hemisphere, autumn begins in the Southern Hemisphere.
In case you are wondering, the official arrival of spring today is at 11:57am CDT.
