Good morrow, Benedick. Why, what's the matter,
That you have such a February face,
So full of frost, of storm and cloudiness?

As we are now in February, you may as well know that this is the month of purification; specifically the Roman festival of purification or Februarius was held on the 15th.
Februa was the Latin for purification, and quite possibly derived from an older word for sulphur, making this sulphur-month. This means that February has some rather odd neighbours in the dictionary, such as februate, which means to purge souls by sacrifice or prayer.
Before this new-fangled Roman stuff came in, the Anglo-Saxons had a much apter name for the month. They called it Solmonath, or Mud-Month.
Mind you, the Venerable Bede called it the month of cakes, because apparently that's what pagans gave to their gods for a winter's snack.
