Times of daylight at different locations in Alaska

So far north, one should include the daylight variation in the travel preparations. The diagrams on this page show times of daylight, twilight, and night, for several locations in Alaska. The time scale is given as local time, while the time used is normally the zone time. The correction is given for each location for the daylight saving time period. Mountains that might in between you and the midnight sun are, of course, not taken into account.
Legend:
  • white - sunlight
  • light grey - "civil twilight". Sun between 0 and 6 degrees below the horizon. The light usually is sufficient to read.
  • medium grey - "nautical twilight". Sun between 6 and 12 degrees below the horizon. Rather dark already.
  • dark grey - "astronomical twilight". Sun between 12 and 18 degrees below the horizon. For non-astronomers, there is hardly any difference to "real" night.
  • black - night.
Calculations were performed using Skyplot IIId on Atari.
for comparison: Augsburg, Germany, 48°18' n.Lat., 10°54' e.Long.
zone time = local time + 1h 16min
Augsburg
Seward, 60°10' n.Lat., 149°30' w.Long.
zone time = local time + 1h 58min
Seward
Anchorage, 61°12' n.Lat., 150°00' w.Long.
zone time = local time + 2h 00min
Anchorage
Talkeetna, 62°17' n.Lat., 150°10' w.Long.
zone time = local time + 2h 01min
Talkeetna
Denali, Medical Camp, 63°03' n.Lat., 151°00' w.Long.
zone time = local time + 2h 04min
Denali
Marion Creek (Coldfoot, Dalton Highway), 67°20' n.Lat., 150°08' w.Long.
zone time = local time + 2h 01min
Marion Creek
Atigun Pass, 68°08' n.Lat., 149°30' w.Long.
zone time = local time + 1h 58min
Atigun Pass
Deadhorse, 70°15' n.Lat., 148°30' w.Long.
zone time = local time + 1h 54min
