: I just dug out an old sunrise/set calculating spreadsheet I found years
: ago, and at NY Alesund's latitude, the midnight sun lasts from
: 17/4-26/8.

At Longyearbyen on Svalbard (Spitzbergen) the midnight sun runs from 20th
April to 24th August

It's interesting to see how rapidly the length of the night increases once
the sun does go below the horizon again.
