HONEST AT THE EDGES DayLighter handles the far north and south honestly, from the midnight sun to the polar night, and tells you plainly when the sun stays up or down all day.

A NOTE ON TIME Times show in each location's own local clock, estimated on device so the app needs no network. For a far-off place this can differ from its daylight-saving clock by up to an hour.
