Groundhog Day is celebrated every year on Feb. 2. Some questions have surfaced about the holiday, including: why do people celebrate Groundhog Day, and what is it? Well, worry no more! The answers are here to satisfy your curiosity.

First off: what is Groundhog Day? It is a popular tradition celebrated in Canada and the United States. According to CNN, “This tradition started in Europe as Candlemas Day. Germans who settled in Pennsylvania in the 1700s brought the custom to America.”

Second question: Why do people celebrate Groundhog Day? Besides celebrating a cute rodent that hibernates underground, it derives from the Pennsylvania Dutch superstition that if the groundhog spots its shadow (if the weather is sunny) it’s a sign that there will be six more weeks of winter. If not, then it indicates that spring is on the way. Seems like groundhogs don’t need to check the weather channel to see if it will be chilly next Sunday.

Many think that there couldn’t be people who actually celebrate the holiday. Well, there was a ceremony held at the Punxsutawney in western Pennsylvania, centering around a semi-mythical groundhog named Punxsutawney Phil. Live Science states, “Phil predicted an early spring. He got it right seven times, that’s a 47 percent accuracy rate.” Now that’s an interesting fact!

Groundhogs are very intelligent, aren’t they? They seem to predict the weather very nicely. This only leads us to wonder just how clever other animals can be.
