Groundhog Day is a traditional holiday in the United States and Canada in which a groundhog named Punxsutawney Phil predicts the end of winter. Each year in Punxsutawney, Pennsylvania, Phil comes out of his hole in front of thousands of people to look for his shadow.
If he sees his shadow, this predicts 6 more weeks of winter.
If he doesn’t, spring is on the way.
There are several groundhogs throughout Canada and the U.S. who predict the forecast for their towns, but Punxsutawney Phil is widely considered the “official” groundhog. His predictions are correct 39% of the time.
