Groundhog Day marks its 1 39th anniversary on February 2, continuing a folk tradition that began in 1887 in Punxsutawney, Pennsylvania.

It's Groundhog Day for Americans living in frigid conditions as Punxsutawney Phil predicted another six weeks of winter on Monday.

The date isn’t random; it’s one of Earth’s cross-quarter days, the halfway point between the winter solstice and spring equinox.
