The first Groundhog Day was observed in 1887 in Punxsutawney, Pennsylvania.
On Groundhog Day, a groundhog, named Punxsutawney Phil, in the small town of Punxsutawney, emerges in the morning to a large crowd. If Phil, sees his shadow, there will be 6 more weeks of frigid weather. If Phil looks down, and does not see his shadow, the Spring is on the way and we are given hope for sunshine and warmth.
Phil's success rate at predicting the weather is only about 39%.
Groundhogs typically have a lifespan of 6-8 years. However, each groundhog day, Phil is given a "Magical Potion" to extend his life for seven more years!
