This includes information about sunrise, sunset together with data of the blue hour, golden hour and twilight times (civil, nautical and astronomical). Furthermore you can calculate information about moonrise, moonset, moon phases and moon illumination (calculated data are approximations of +/- 1 day accuracy).In this app you can view data for multiple locations.
