"It's broken down like this: meteorological spring includes March, April, and May; meteorological summer: June, July, August; meteorological fall: September, October, November; and meteorological winter: December, January, February, and March." Hey, wait a minute. That's TWO Marches, one in spring, and one in winter! That's thirteen months, just the way Phil Silvers counted the shares in It's a Mad Mad Mad Mad World! Well, March, are you winter or spring????
