How to Celebrate Groundhog Day

Groundhog Day is celebrated in the United States and Canada on February 2nd. Based on trying to guess when winter is going to end, the tradition holds that if the groundhog (Marmota monax) pops his head out but sees a shadow when emerging from its burrow, and pops back down, winter will go on for another six weeks. But, if it doesn't see its shadow, and the groundhog comes out of its burrow, then it's thought that winter will be over soon.[
