Imbolc: Straight from Wikipedia
Imbolc was traditionally a time of weather divination, and the old tradition of watching to see if serpents or badgers came from their winter dens may be a forerunner of the North American Groundhog Day. A Scottish Gaelic proverb about the day is:
Thig an nathair as an toll Là donn Brìde, Ged robh trì troighean dhen t-sneachd Air leac an làir.
The serpent will come from the hole On the brown Day of Bríde, Though there should be three feet of snow On the flat surface of the ground.[37]
Imbolc was believed to be when the Cailleach—the divine hag of Gaelic tradition—gathers her firewood for the rest of the winter. Legend has it that if she wishes 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 would be relieved if Imbolc is a day of foul weather, as it means the Cailleach is asleep and winter is almost over.[38] At Imbolc on the Isle of Man, where she is known as Caillagh ny Groamagh, the Cailleach is said to take the form of a gigantic bird carrying sticks in her beak.[38]
