What the data shows
Day length in Anchorage ranges from 5 hours 27 minutes on 21 December 2026 to 19 hours 23 minutes on 21 June 2027 — a swing of 13 hours 56 minutes.
How we calculated this: Longest and shortest sunrise-to-sunset span over every day of the period.
From 7 June 2027 to 4 July 2027 the sun sets but it never gets darker than civil twilight (white nights).
How we calculated this: Days with a sunset whose civil dusk never arrives (sun stays above 6° below the horizon).
Clocks in Anchorage run 2 hours 9 minutes ahead of the sun at the extreme: on 14 March 2027 the sun is highest at 14:09, so mornings stay dark later and evenings light longer than the clock suggests.
How we calculated this: Largest gap between 12:00 local clock time and solar noon over the period.
In Dec 2026 the sun never climbs more than 6° above the horizon in Anchorage, so golden-hour light lasts all day instead of two short windows — on 15 December 2026 from 09:30 to 16:20.
How we calculated this: Golden hour: sun between 6° above and 4° below the horizon; blue hour: 4°–6° below (geometric elevation of the sun’s centre, NOAA equations), on the 15th of each month. Months (15th) on which the sun's highest point stays below 6°.
The earliest sunrise is at 04:20 (16 June 2027) and the latest sunset at 23:43 (20 June 2027), local clock time.
How we calculated this: Earliest sunrise and latest sunset (local clock) over every day of the period.
Clocks go back 1 hour at 02:00 on 1 November 2026 and go forward 1 hour at 02:00 on 14 March 2027, shifting sunrise and sunset by the same amount overnight.
How we calculated this: UTC-offset changes of America/Juneau in tzdb 2026e during the period.
