The SunCalc widget calculates all useful times for the sun, like sunset, sunrise, dusk, dawn, blue hour, golden hour.
Press "Start" to browse through the list of times with "Up" and "Down". Press "Start" again to refresh the GPS position. Press "Back/Lap" to exit.
Blue Hour and Golden Hour are very useful for photographers. Dusk and Dawn, if you want to do some outdoor activities.
