Groundhog Day

Groundhog Day, February 2. Used to forcast the weather. According to superstition, when the ground hog emerges from his winter burrow on this day, if he sees his shadow, he returns, and the winter will last for six more weeks. If he does not see his shadow, i.e. the day is cloudy, then he remains outside in anticipation of an early spring. This legend is probably an American version of the ancient belief that a sunny Candlemas (also February 2) predicts a cold spring.
Other days with weather superstitions include Saint Swithin's Day, [saint vincent day]...
