We call it Groundhog Day
This is the when Groundhog a furry rodent comes out from the hole and people predict weather from it's shadow. On this day if groundhog sees its shadow, there will be six more weeks of winter weather; no shadow means an early spring.
Groundhog Day has its roots in the ancient Christian tradition of Candlemas Day, when clergy would bless and distribute candles needed for winter. The candles represented how long and cold the winter would be. Germans expanded on this concept by selecting an animal–the hedgehog–as a means of predicting weather. Once they came to America, German settlers in Pennsylvania continued the tradition, although they switched from hedgehogs to groundhogs, which were plentiful in the Keystone State.
Since then, the tradition has grown in popularity with many other cities across the country hold their own Groundhog Day celebrations. But none are as elaborate as the one that takes place at Gobbler’s Knob in Punxsutawney, Pennsylvania every Feb 2.
