How long does golden hour last in Rovaniemi?
Around 101 to 188 minutes each evening. It's shortest in March and September, about 101 minutes, and longest in May, about 188 minutes. In June and July there's no ordinary evening window: the sun stays high through the night. In January, November 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.
