American Groundhog Day - 02 February each year
Groundhog day first started on 02 February 1886 in Punxsutawney, Pennsylvania.  It is a popular tradition in the United States. 

It is the day that the Groundhog comes out of his hole after a long winter sleep to look for his shadow.

The Groundhog is believed to be able to predict the weather … the onset of Spring … by whether or not it sees its shadow when it emerges from its burrow.

  • No shadow means an early Spring - if the day is cloudy and shadowless, the Groundhog takes it as a sign of Spring and stays above ground..
  • A shadow means Winter will continue for another six weeks. The shadow means that the Groundhog will return to its burrow.

02 February 2014:  The Groundhog predicted that to was NOT the onset of Spring, and returned to its burrow.
