Which has more hours of daylight?

Los Angeles or here? Mexico City or Anchorage? I know we've got longer days in summer than Southern California, and shorter ones in winter; but what's the total? Do they cancel each other out? Are they equal? I'm not talking about sunshine, obviously; just daylight -- dawn to twilight preferred, but I'll take sunup to sundown. I've always wondered this, but I can't find it online anywhere.

    I think it should be the same: whatever your night-to-day ratio is when you're on one side of the sun, six months later, you're at the opposite side of the sun, the angle of earth's inclination is now the opposite with regard to the sun, so you get the opposite ratio. So all points on the globe end up getting an overall annual ratio of 50:50.

    However: the closer to the poles you are, the more gradual the transition between night and day; depending on your purpose, these twilight hours may or may not count as real daylight. So you could claim that there's more proper daylight closer to the equator.

    this was the first hit I got with "sunrise sunset charts"

    It'd take some doing, but you can create a calendar for different locations that list day length.
