Groundhog Day (Sunday)
On Groundhog Day, February 2, a groundhog is said to forecast weather by looking for his shadow. If it’s sunny out, and he sees it, we’re in for six more weeks of winter. On the other hand, a cloudy Groundhog Day is supposed to forecast an early spring. It has its roots in astronomy, in the sense that it’s a seasonal festival, tied to the movement of Earth around the sun.
