Lands Of The Midnight Sun


This is a list of dates and latitudes where the sun doesn't set for days on end.

It might be a useful resource for anyone interested in the Arctic or Antarctic.

I've posted it under 'science and society' because these days a lot of people go on vacation to see the midnight sun. 

Tourists + awesome spectacle = science education.  Because society needs it.
