Taking place almost halfway between the winter solstice and the spring equinox, Groundhog Day is an annual event when groundhogs are brought outside and are observed to see if they see their shadow or not. If they see their shadow, it is said that there will be six more weeks of winter. If they do not, it means the weather will be mild in the upcoming weeks, and spring will come early.
Its GroundHog day. Did Phil see his shadow.
