Curious to know how this little creature reached such notoriety in predicting longer Winters or early Springtime? Here's everything you ever wanted to know about the famous Groundhog...
Groundhog Day 2005 in Punxsutawney, Pennsylvania, USA
Groundhog Day is a holiday celebrated on February 2nd in the United States and Canada. According to folklore, if it is cloudy when a groundhog emerges from its burrow on this day, it will leave the burrow, signifying that winter will soon end. If it is sunny, the groundhog will supposedly see its shadow and retreat back into its burrow, and winter will continue for six more weeks.
Modern customs of the holiday involve celebrations where early morning festivals are held to watch the groundhog emerging from its burrow. In southeastern Pennsylvania, Groundhog Lodges (Grundsow Lodges) celebrate the holiday with fersommlinge, social events in which food is served, speeches are made, and one or more g'spiel (plays or skits) are performed for entertainment. The Pennsylvania German dialect is the only language spoken at the event, and those who speak English pay a penalty, usually in the form of a nickel, dime or quarter, per word spoken, put into a bowl in the center of the table.
The largest Groundhog Day celebration is held in Punxsutawney, Pennsylvania. Groundhog Day, already a widely recognized and popular tradition, received worldwide attention as a result of the 1993 film of the same name, Groundhog Day, which was set in Punxsutawney and featured Punxsutawney Phil.
 Famous groundhogs and predictions
Many towns that celebrate Groundhog Day throughout North America have winter-predicting groundhogs. By far, the most notable groundhog is Punxsutawney Phil of Punxsutawney, Pennsylvania. Other groundhogs of note include Smith Lake Jake, Staten Island Chuck, General Beauregard Lee, Shubenacadie Sam and Wiarton Willie.
Groundhog Day proponents state that the rodents' forecasts are accurate 75% to 90% of the time. A Canadian study for 13 cities in the past 30 to 40 years puts the success rate level at 37%. Also, the National Climatic Data Center reportedly has stated that the overall prediction accuracy rate is around 39%.
