It is February 2, and that means that folks are looking to the groundhog to see if there will be six more weeks of winter. You can check out the most famous quadrupedal weatherman, Punxatawney Phil, out in western Pennsylvania or any number of imitators around North America (or celebrate Marmot Day in Alaska).
Even National Geographic has a story about the Groundhog Day tradition!
The origins of Groundhog Day date back to the earliest pagan rituals associated with the changing of the seasons. February 2 falls exactly between the first day of winter (the winter solstice) and the first day of spring (the vernal equinox), and so was very important to early astronomers.
In pre-Christian Europe the festivals surrounding Imbolc, the holiday marking the midpoint between winter and spring, often dealt with predicting the weather and checking for signs of spring, looking for hibernating animals to return or not. Later Christians incorporated the holiday of Candlemas to replace the pagan holiday.
The tradition of Groundhog Day may come from a poem about Candlemas:
As the light grows longer
The cold grows stronger
If Candlemas be fair and bright
Winter will have another flight
If Candlemas be cloud and rain
Winter will be gone and not come again
A farmer should on Candlemas day
Have half his corn and half his hay
On Candlemas day if thorns hang a drop
You can be sure of a good pea crop
Whatever the origin, Groundhog Day is definitely one of those weird, funny holidays. It was also the subject of a hilarious movie starring Bill Murray.
