What is Groundhog Day? -

Groundhog Day is a popular North American tradition celebrated annually in the United States and Canada. On February 2, a groundhog is enticed from its burrow. If the rodent sees its shadow, it gets scared and runs back into its den, predicting six more weeks of winter weather; no shadow means an early spring. In theory!

Weather lore -

Although it's a uniquely North American tradition, the history of this unusual ceremony stretches back hundreds of years to European weather lore and the ancient Christian tradition of Candlemas.

Candlemas -

Traditionally, the celebration of Candlemas saw clergy bless and distribute candles needed for the dark winter months. The candles represented how long and cold the season would be.

Animals used to forecast the weather -

In German-speaking areas of Europe, people began using animals to forecast the weather, typically badgers and hedgehogs—creatures that would normally hibernate during the winter months. Marmots were also used. The use of animals in this way is based on superstition and appears to be an enhanced version of the lore that clear weather on the Christian festival of Candlemas forebodes a prolonged winter.

Pennsylvania Dutch -

This superstitious mindset was carried over to the United States during the 18th and 19th centuries when predominantly Dutch and German immigrants settled in Pennsylvania and Virginia—and groundhogs quickly became the creature of choice used to maintain the tradition.

Early ceremonies -

According to the New World Encyclopedia, Groundhog Day in America dates back to at least 1841. In that year on February 4, a Morgantown, Pennsylvania, storekeeper called James Morrison noted in his diary the German tradition of using a groundhog to forecast the weather. Morris' diary is in the collections of the Historical Society of Berks County, in Reading, Pennsylvania. Pictured are benches marking the state border between West Virginia and Pennsylvania.

Why predict the weather? -

Farmers needed ways to forecast the weather, as they were dependent on their harvests. They faced a constant struggle to earn a living and provide for their families. The use of a groundhog to predict the arrival of spring was therefore not only a way of upholding a long-held tradition, but seen as a means of organizing labor and prioritizing tasks accordingly.

First official ceremony -

The first official Groundhog Day in the United States was celebrated on February 2, 1886, in Punxsutawney, Pennsylvania.

Punxsutawney Groundhog Club -

Punxsutawney resident Clymer Freas (1867–1942) is credited as the "father" who conceived the idea of Groundhog Day. The Groundhog Day celebrations of the 1880s were carried out by the Punxsutawney Elks Lodge. The Punxsutawney Groundhog Club was founded in 1899.

What's in a name? -

It's at Gobbler's Knob on February 2 that the groundhog makes his long-awaited appearance. The furry rodent is known as Phil. But why this name?

Punxsutawney Phil -

The origins of Punxsutawney Phil's name are as obscure as they are colorful. Once known simply as the "Br'er Groundhog," some suggest he was christened after the city of Philadelphia. Others insist he's named for a King Phillip, but that explanation is as dubious as it is vague in so far as it's never been specified which King Philip is being referred to.

What is a groundhog? -

Actually, at this point it's worth explaining exactly what a groundhog is. Also known as a woodchuck, the mammal belongs to the group of large ground squirrels known as marmots, and is found through much of the eastern United States, across Canada, and into Alaska.

America's original weather-forecasting groundhog -

The Punxsutawney Groundhog Club declared long ago that Phil, the Punxsutawney groundhog, was America's only true weather-forecasting groundhog. The others are just imposters. But what others?

Other weather-predicting rodents -

Many towns across North America now have their own weather-predicting rodents, from Georgia's General Beauregard Lee to Staten Island Chuck (pictured) to Wiarton Willie in Ontario, Canada.

How accurate is Punxsutawney Phil? -

Punxsutawney Phil has been forecasting the weather on Groundhog Day for more than 120 years, but just how good is he at his job? Well as it turns out, his track record for weather prediction isn't 100% … or even 50%, according to EarthSky.

Shadowy figures -

Groundhog Club records note that since 1887, Phil and his predecessors have seen their shadow 104 times, and not seen it only 19 times.

Missing years -

Oddly, there are nine years without any records, an anomaly even the the Punxsutawney Area Chamber of Commerce, which keeps track of these things, can't explain.

Percentage of correct predictions -

After crunching the numbers, data released by the Stormfax Almanac, which has been tracking Phil's predictions since 1887, confirms that the celebrated groundhog has been correct only 39% of the time.

100% accurate! -

But speak with any member of the the Punxsutawney Groundhog Club's Inner Circle, however, and they'll insist that Phil's predictions are 100% accurate.

Groundhog day attire -

Late winter or early spring? -

Depending on Phil's prediction— already imparted to the Inner Circle's president—the vice president will then read out from one of two prepared scrolls, either proclaiming six more weeks of winter or an early spring.

Proclamation! -

The proclamation is announced at dawn in front of a sizeable crowd of people, many of whom have been partying for much of the night.

Groundhog Day in popular culture -

Groundhog Day has been portrayed in various media, as early in fact as 1935 when the cartoon 'Summertime' featured the weather-predicting rodent.
