This Day in History: <br />The First Groundhog Day February 2, 1887 Groundhog Day was celebrated <br />for the first time at Gobbler’s Knob <br />in Punxsutawney, Pennsylvania. Tradition has it that if a groundhog comes <br />out of its hole on this day and sees its <br />shadow, it runs back into its burrow, <br />predicting six more weeks of winter. No shadow means <br />an early spring. In 1887, a newspaper editor <br />declared that Phil, the <br />Punxsutawney groundhog, was <br />America’s only true weather-forecasting groundhog. The line of groundhogs that <br />have since been known as Phil <br />are America’s most famous marmots. The 1993 movie, 'Groundhog Day,' <br />starring Bill Murray, popularized <br />the usage of the term to mean <br />something that is repeated over and over.
