Unless you live in Punxsutawney, Pennsylvania, there's a pretty good chance you don't know that today is Groundhog day. Or maybe you know because, like me, you are a fan of a movie with Bill Murray called "Groundhog Day" (Un jour sans fin in French). In this comedy Phil (Murray) is trapped in a timeloop and lives the same day over and over again. That particular day happens to be the 2nd of February when Phil is in Punxsutawney to cover the biggest celebration of this holiday.

If you have still no idea of what I talking about, just check the video it explains everything. For more information check the Wikipedia page and learn how groundhogs are used to predict the end of the winter. Apparently, if one leaves its burrow and sees its shadow (i.e. on a sunny day), then it will retreat to its burrow and that will mean that the winter will last 6 more weeks.

You might also be interested in knowing that in Alaska, it's not Groundhog Day anymore but Marmot Day, thanks to a bill signed by Gov. Sarah Palin in 2009.
