Get ready for the Vernal equinox or some may say the Spring equinox. At 5:58 PM today it will be the official Start of Spring 2019.
There are only two times of the year when the Earth's axis is tilted neither toward nor away from the sun. When this happens it results in nearly equal amounts of daylight and darkness. These events are referred to the name Equinoxes and will occur twice a year. It will happen today, March 20th, at 5:58 PM. (Vernal Equinox - the first day of Spring) and it will happen again on Monday September 23rd at 3:50 AM. (Autumnal Equinox - the first day of fall).
Fun fact: The word equinox is derived from two Latin words - aequus (equal) and nox (night).
