The celebration of the true cross-quarter day, the 3rd for the Eve and the 4th for the Day, at least this year, is called GroundFrog Day to avoid confusion with Groundhog Day. The definitive story is:

De GroundFrog come up out de hole an he look aroun
Den he open one eye an he look around some more
Den he open de nother eye
An if de nother eye see the one eye dey gone be 40 days an 40 nights of rain
Or winter
Whichever more convenient.
