In autumn, are the days shorter in...

On the days of the spring and fall equinox everybody on earth has approximately 12 hours of daylight and 12 hours of night. As winter approaches on the northern hemisphere, the days get shorter and the nights get longer, but much less so for California (approximately 37 degrees latitude) than Alaska (approximately 65 degrees latitude). For an observer above 66.5 degrees latitude, the sun does not rise at all. There they experience only twilight at about noon. Further north, even that disappears into a long polar night.
