Earth

Your own sky, worked out for your own town. Sunrise and sunset, tonight's moon and how full it is, and when the tide turns — for more than a thousand cities, on whatever date you pick. Every figure is computed from the real motions rather than looked up in a table.

Sunrise & Sunset

The cities below run north to south. The farther from the equator, the more day length swings with the season — long summer days, short winter ones.
