You know it's winter when you leave home for work in the dark and get home in the dark.
You know it's really winter when you leave home in the dark, travel to London and when you arrive it's still not light.
Twilight comes early and rather quickly at this time of year, but the good new is, from 04.48GMT on 22nd December, the winter solstice, the shortest day in the northern hemisphere which marks the first day of winter, the nights start drawing out and summer's on the way.
