Groundhog Day is a traditional holiday celebrated in the United States and Canada on February 2nd. According to folklore, if a groundhog emerges from its burrow on this day and sees its shadow due to clear weather, it will retreat back into its den, indicating that there will be six more weeks of winter. If it does not see its shadow because of cloudiness, it will stay outside, signifying that spring will arrive early. The most famous Groundhog Day celebration takes place in Punxsutawney, Pennsylvania, featuring a groundhog named Punxsutawney Phil.
