Did you know the Christian roots of Groundhog Day and its connection to Candlemas?
From the Old Farmer's Almanac
It's no accident that Groundhog Day and Candlemas are celebrated together, for both signify the triumph of light over darkness, spring over winter.
Candlemas was originally a Celtic festival marking the "cross-quarter day," or midpoint of the season. The Sun is halfway on its advance from the winter solstice to the spring equinox. The Christian church expanded this festival of light to commemorate the purification of the Virgin Mary and her presentation of the infant Jesus in the Temple. Candlelit processions accompanied the feast day.

A bear brought the forecast to the people of France and England, while those in Germany looked to a badger for a sign. In the 1800s, German immigrants to Pennsylvania brought their Candlemas legends with them. Finding no badgers but lots of groundhogs, or woodchucks, there, they adapted the New World species to fit the lore.
