Yellow is direct sunlight, blue is dawn twilight, pink is dusk twilight, grey is darkness.

Ah yes, so even at the two equinoxes there's at least an hour of twilight at either end of the day, more than there would be at the Equator, and three hours on December 21st. It looks like there's no true darkness from late April to mid August according to that.

Looking at this one for for the South Pole on 21st September it looks like roughly 12.5 hours of sunlight and 11.5 hours of twilight, which must be an odd experience.

I would love to see the midnight sun and the polar night.. but I could not live there, especially during constant light when it becomes very hard to sleep (I'm assuming). Heck, here in the UK, it's hard to get kids to sleep at 9pm because it's still sunny.

Since when does civil twilight count as complete darkness?

I could live with the darkness (I think) but probably not the extreme cold

Barrow is too cold even for me.
