Earliest Sunset a Few Days Before. If you look at the sunrise and sunset times for any city in the Northern Hemisphere around the December Solstice, you will notice that the earliest sunset occurs a few days before the solstice and the latest sunrise happens a few days after the solstice.
For example, in Fairbanks, the sunrise on this year's summer solstice (June 20) is at 2:59 a.m. Sunset is at 12:47 a.m. the next day. For those two hours between sunrise and sunset, it's basically dusk or dawn because it never actually gets dark. This all-day daylight occurs May 17-July 27 in Fairbanks.
