Happy Summer?

Go ahead - keep confusing the hell out of me! On Saturday, May 31, the meteorologist kept saying this is the last day of Spring -- tomorrow is the first day of summer. What?? Never heard that before. So.... I dove into the Internet - I never knew this -- There are "astronomical" seasons and "meteorological" seasons. Go figure!! So, the meteorological seasons (based on the changing temps) consist of 4 months each - Mar-May, Jun-Aug., Sep-Nov, Dec-Feb. OK, I got it. Good grief. and... HAPPY SUMMER, Y'ALL!
