Strange, but true: this happens during early August in Northwest Alaska. For example, in the city of Kotzebue (Qikiqtaġruk), Sunday, 7 August 2016 will begin with sunset just after midnight. The sun will then rise (on Sunday) at 5:52 a.m. It will set again, for the second time, still on Sunday, at 11:57 p.m.

The double sunset in one calendar day is a peculiarity of Kotzebue's latitude, longitude and time zone. Kotzebue, located just above the Arctic Circle, has not always had the peculiarity of having the sun set twice in a single day. When Alaska's four times zones were squeezed into two in an attempt to make people feel closer together, Kotzebue changed time zones, giving it the remaining ingredient necessary for the double sunset.
