4. Didn't spring start already? Meteorological spring started March 1. Forecasters like to start the season on the first day of March because they prefer a calendar in which each season starts on the same day every year. It helps with record keeping, among other reasons. But the Earth, sun and stars don't quite conform to the Gregorian calendar – thus the vernal equinox doesn't fall on the same day every year.
5. What's next? The summer solstice is June 21, but meteorological summer begins a few weeks earlier on June 1.
