Sure, but the fact is that there are six weeks between February 2 and the Vernal Equinox whether the G-hog sees its shadow or not. What I find interesting, and I'm not sure just why I do, is that the Google calendar lists it's day as a holiday in Canada, but not in the US. There is an implication that the day must have some greater significance in Canada, at least in somebody's mind.
A resident in a climate very similar to that of neighboring Victoria BC, I suspect that out this way, it would seldom see its shadow because our winter skies are typically gray. Yesterday was an exception. It was clear and cold, maybe more like in Pennsylvania where the "official" US groundhog resides.
