Not counting Alaska, International Falls, MN has Sunrise at 8:00 AM and Sunset at 4:20 PM. CT has about an hour more. But these places are not Phoenix, and if it is overcast (often) it is actually pretty dark even within those hours. I grew up in Connecticut, and if you have a commute of any length or a bit of a walk from school (yes, I walked or rode a bike), you spent time in darkness.
I also grew up in the north, walked to school in the dark, shoveled snow in the dark when got home, only daylight hours outside were walking home from school and weekends. It got dark around 5 pm .
