Groundhog Day got it's start in Pagan traditions. Imbolc is the day the Cailleach (The Goddess of Nature) gathers her firewood for the rest of the winter. Legend has it that if she intends to make the winter last a good while longer, she will make sure the weather on Imbolc is bright and sunny, so she can gather plenty of firewood. Therefore, people are generally relieved if Imbolc is a day of foul weather, as it means the Cailleach is asleep and winter is almost over.
The holiday is a festival of the hearth and home, and a celebration of the lengthening days and the early signs of spring.
Think of Imbolc as Thanksgiving celebration for what is about to happen. Have a drink and a feast, knowing that winter is passing and that food will once again be growing and plentiful.
It's 20 degrees and icy in Dallas today. I'm OK with that if it means Spring will be coming sooner! I'll open and enjoy a bottle of Lambic with a nice dinner tonight!
And Happy Groundhog Day tomorrow.
