Do you mean warmer than -20, or colder than -20? Here were Edmonton's temperatures this past January. We ranged from -42 to +10, but the average max/min/mean temperatures were -5.3C, -20.8C, and -13.1C (that is: on average, we didn't go below -20, and then those lows were in the late night/very early morning).

Sunset right now (not the height of summer) is already 8:41pm, and then dusk lingers for about 30 minutes past that. At the height of summer, it doesn't get really dark until past midnight (although it's probably too dim to golf before that).

But yes, in the winter, it gets dark around 4:30pm. But it's usually sunny while the sun is up! (if you're not stuck in the office from 8am-5pm...)
