Groundhog Day 2012: 10 Facts About The Day, The Animal And Punxsutawney Phil (PHOTOS)

How much do you know about Groundhog Day?

The February 2 celebration, which involves a weather-predicting woodchuck, dates back to the late 19th century, with other mid-winter weather holidays dating back hundreds of years before that.

On Groundhog Day, a groundhog in the small town of Punxsutawney emerges in the morning to a throng of onlookers. If he spots his shadow and returns to his hole, it means winter will last six more weeks. If the groundhog does not see his shadow, an early spring is sure to come.

Not to be outdone, many other towns now have their own woodchuck weathermen.

Punxsutawney Phil is the original star of Groundhog Day, however. He first predicted the weather 126 years ago and has had about 39 percent accuracy ever since. Click here to see the see the groundhog's predictions from the past 10 years.

Below, check out 10 interesting and little-known facts about Groundhog Day, groundhogs and even the movie "Groundhog Day."

A Different Prediction

Punxsutawney Phil rival Woodstock Willie also made a prediction today, but his forecast differs from Phil's. Willie, who is from Woodstock, Illinois, didn't see his shadow, delighting midwesterners with the promise of an early spring.

Will He Be Right?

Staten Island Chuck (aka Charles C. Hogg), New York City's answer to Punxsutawney Phil, did not see his shadow this morning and "predicted" an early spring.

He also predicted a New York Giants win at this Sunday's Super Bowl XLVI. Many New Yorkers are hoping that Chuck is right.
