On Earth, December was the month which contained the holiday of Christmas and the phenomenon known as the winter solstice. As a consequence, it contained the exact midpoint of winter and therefore the instant when people were, in the words of Kazran Sardick and the Eleventh Doctor, "halfway out of the dark".
