A tardy note on the Gaelic holiday of Imbolc, traditionally held on February 1 and associated with the onset of spring – or a prolonged winter.
From Wikipedia:
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. 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.
Cailleach would be a great name.
