For me, it's dark by 5:30pm from about mid October (even with daylight savings) to the end of February. It's way more than two weeks.
And that's if you get out of work at 5 every day. Lots of us get out later (say, 6 or 6:30) and then have at least a half hour commute.
The only time I see the sun in winter is in the morning. With daylight savings in effect I lose that too. Those extra few weeks they tacked onto daylight savings at the end of October are dark and brutal.
