As good as any...
We're well into the second half of winter now, with Imbolc a week behind us. After the Roman invasion of Britain it became known as St. Brigid's Day (they brought their official religion with them), but it still marks us half-way through the winter and moving toward the light, although the old Celts claimed it was really the first day of spring.
I'm fine with that. It's as good a beginning as any.
