SunCalc Provides a Map View for Checking Sunlight and Golden Hour

SunCalc is a super-simple web app created with Google Maps and Javascript that helps you determine the best time to shoot depending on the quality of light you want in your photos.

You can see sun positions at sunrise, specified time and sunset. The thin orange curve is the current sun trajectory, and the yellow area around is the variation of sun trajectories during the year. The closer a point is to the center, the higher is the sun above the horizon. The colors on the time slider above show sunlight coverage during the day.

It was created by Vladimir Agafonkin. Similar apps include The Golden Hour Calculator and The Twilight Calculator.
