How long does golden hour last in Fairbanks?
Around 94 to 179 minutes each evening. It's shortest in September, about 94 minutes, and longest in November, about 179 minutes. In June and July there's no ordinary evening window: the sun stays high through the night. In January and December the sun stays low all day, so the gold merges into one long window or doesn't come at all. The farther from the equator, the longer it lasts, because the sun crosses the horizon at a shallower angle.
