Groundhog Day is an American tradition that occurs on February 2nd. Groundhog Day derives from a superstition that if a groundhog sees it's shadow it will mean there are six more weeks of winter. People living in the southern hemisphere of the world experience summer while the people in the north experience winter. Different global cultures define the dates of seasons differently.
