Groundhog Day: A Unit Study

Groundhog Day: A Unit Study

Every child knows the basics of Groundhog Day.

On February 2, the groundhog peeks out of his hole to decide if he wants to take the trouble of staying awake or if he would rather sleep in a while longer:

  • If the sun is out, he casts a shadow which is apparently frightening enough that he promptly decides to return to the safety of his bed.
  • If the weather is cloudy, no shadow meets his eye and he comes out of his hole, marking the beginning of spring.

But did you ever wonder where in the world we came up with this strange custom?

The History of Groundhog Day

Groundhog Day traces its origin to ancient times. The story goes that Candlemas Day, originally a Roman Catholic celebration of Mary’s ceremonial purification after Jesus’ birth, somehow picked up the reputation of being an indicator of upcoming weather conditions.

An old folk saying proclaims:

If Candlemas be fair and bright,
Winter will have another flight.
If Candlemas be cloud and rain,
Winter will be gone and not come again.

The Romans supposedly carried the Candlemas tradition to Germany, where it was absorbed into the pagan festival of Imbolc, a celebration of the changing of the seasons. The pagans logically concluded that if the sun was out on February 2, an animal would cast a shadow. The hedgehog was evidently held in high regard in their culture, and thus was chosen to forecast the weather. The tradition was handed down throughout the generations, and when the descendants of the ancient Germans set foot in Pennsylvania in early American history, the legend arrived with them.

Groundhog Day: A Unit StudyHedgehogs are scarce in Pennsylvania, but the settlers did encounter an abundance of groundhogs, also known as woodchucks. These marmots, or large ground squirrels, seemed intelligent enough, and they bore some slight resemblance to hedgehogs, so the settlers conferred the honor of predicting the arrival of spring on the groundhog.

Punxsutawney Phil

At first Groundhog Day wasn’t much of a celebration, mostly consisting of a few curious country folk taking a walk in the woods to see if the marmots had come out of hibernation. But on February 2, 1887, the first official procession was made to Gobbler’s Knob — the home of Punxsutawney Phil.

Punxsutawney Phil is the only true groundhog forecaster, proponents say. Buckeye Chuck, Smith Lake Jake, Jimmy the Groundhog, and all the others are merely imposters. Regardless of what skeptics say to the contrary, Phil is reputed to have been around for over a hundred years. His advocates claim that just one sip of the mysterious Elixir of Life every summer provides him with seven more years of existence, so he will never fail to emerge from his burrow and whisper his prediction in Groundhogese to his tuxedo-clad handlers. And with so much forecasting experience, one would fully expect him to achieve the 75% – 90% accuracy rates attributed to him, although the National Climatic Data Center still persists in floating a troublesome estimate of 39%.

About Those Groundhogs

But do not be fooled by Phil’s cute and cuddly image. Groundhogs in the wild live a far different life. They eat crops, they dig up gardens, they undermine buildings, and, while not exactly aggressive, they have earned a reputation for possessing extremely powerful jaws. They only live two or three years on average and eight years maximum compared to Punxsutawney Phil’s hundred-plus, and they have to forage for their own fruits and vegetables, instead of being treated to picnics by devoted members of the “Inner Circle.” Then, too, they rarely range far from their massive burrows for fear of encountering a bear, fox, or snake. That’s a far cry from a cozy home in the Punxsutawney library!

Groundhogs are widely distributed throughout eastern and central North America, ranging as far south as Alabama and as far north as Alaska, although their scarcity in that state has recently prompted the creation of a more generalized “Marmot Day” — yet another modification in the long-held tradition of Groundhog Day.
