The March equinox signaling the start of spring happens at the same moment across the world, but this year it falls on March 20 at 5:45 p.m.

The March vernal equinox occurs when the Sun crosses the celestial equator on its way north along the ecliptic, marking the start of the season.

The Farmer’s Almanac forecast the April and May will be warmer and more rainy than normal on average for Texas and Oklahoma.

Fun facts:
