Maui Sunrise & Sunset Photography

The Golden Hour Calculator is a little app based on SunCalc that shows sun movement and sunlight phases during any given day at any given location. This is especially useful for planning when or where to capture your sunset or sunrise photography.

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.

This is also useful for knowing if the sun will set behind any of the Hawaiian Islands for any given location on any given day.
