Spring starts about Mar 21 ( or Sept 21 - Southern H.) Summer, about June 21 (or Dec 21 - S.H.) Fall, about Sept 21 (or Mar 21 - S.H.) Winter about Dec. 21 (or Jun 21 - S.H.) The exact time varies slightly because the orbit is just slightly more than 4X3 months per season - 365 1/4 days all together.
