There's a whole genre of Minnesota jokes that begin: “Minnesota has two seasons: Winter and....” Winter and Road Repair. Winter and Winter-is-Coming. Occasionally there are variations: “...two seasons: Shovel and Swat.” Whatever one calls its partner, though, Winter is the central fact of existence here in Lake Country. Spring and Fall aren't really seasons in the North; they're occasional delightful visitors, all the more beloved for their poignantly brief stay. Our year really is a bi-seasonal one.
This would have been utterly familiar to the ancestors. The ancient Germanic speakers knew a two-season, Winter-Summer year: etymologically, the “windy” and “sunny” seasons respectively. The great holidays of Proto-Germanic culture were apparently Midwinter and Midsummer, associated even then—between 3000 and 4000 years ago—with the winter and summer sunsteads (solstices). We know that this goes back to the time before the Germanic languages branched off from one another because the terms are preserved in all surviving daughter languages.
