  1. I agree with the 12 hour answer, if you ignore clouds. In other words, the Sun is above the horizon 50% of the time, averaged over a year, for any location on Earth. At the north pole this would be 6 months of daylight followed by 6 months of night every year. At the equator it would be 12 hours of daylight and 12 hours of night every day of the year. At intermediate latitudes, there is more than 12 hours of daylight in summer and less in winter, but it averages out to 50% of the time over a year.


  2. 12 hours

    Averaged over the whole year every where has half its time in light and half in dark.

  3. 12.5 hours
