when is groundhog day and how does it work
Groundhog Day, (Pennsylvania German: Grund'sau dåk, Grundsaudaag, Grundsow Dawg, Murmeltiertag; Nova Scotia: Daks Day) is a popular tradition celebrated in the United States and Canada on February 2. It derives from the Pennsylvania Dutch superstition that if a groundhog (Deitsch: Grundsau, Grunddax, Dax) emerging from its burrow on this day sees a shadow due to clear weather, it will retreat to its den and winter will persist for six more weeks, and if it does not see its shadow because of cloudiness, spring will arrive early. While the tradition remains popular in modern times, studies have found no consistent correlation between a groundhog seeing its shadow or not and the subsequent arrival time of spring-like weather.
