Groundhog Day is an annual celebration that takes place on Feb. 2 throughout Canada and the United States. According to tradition, if it is sunny and the groundhog sees his shadow after emerging from his burrow, he predicts six more weeks of winter weather. If he does not see his shadow, he predicts an early spring. This celebration began as a German custom in Pennsylvania in the 18th century.
