67 days of darkness. Even though residents of Barrow, the northernmost town in Alaska, won't see the sun for 67 days come winter, they enjoy the midnight sun all summer-over 80 days of uninterrupted daylight.
Answers. Best Answer: In Anchorage, about 5.5 hours from sunrise to sunset in December.

Fairbanks is more extreme by a few hours. Juneau and Ketchikan, etc are between Anchorage and Seattle in both temps and light (but much wetter than either). On March 21 and September 21 (the equinoxes) everywhere is 12 hours daylight and 12 hours twilight+night.
