When Jude and I were running the farm the old-timers taught us that you should have half of your hay and half of your firewood left on February 2nd.
The day marks the midpoint between the spring equinox and winter solstice and people have been paying close attention to this day for a very long time.
In particular, there is an interesting parallel between the Celtic holiday of Imbolc and the Groundhog day we all love (hate).
Oh and don’t forget the movie.
Imbolc is the day Cailleach (the Creatrix) 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.[16
Groundhog Day is an annual holiday celebrated on February 2. According to folklore, if a groundhog emerging from its burrow on this day fails to see its shadow, it will leave the burrow, signifying that winter will soon end. If on the other hand, the groundhog sees its shadow, the groundhog will supposedly retreat into its burrow, and winter will continue for six more weeks.
