What golden hour and blue hour are

Photographers mean slightly different things by them. SolarDial uses the sun's height above the horizon:

WindowSun's altitude
Golden hourfrom 6° above the horizon to 4° below
Blue hourfrom 4° below to 6° below

There is one of each in the morning and one of each in the evening. Neither is really an hour: near the equator the sun drops through those bands quickly, while in winter and far from the equator it slides across the horizon at a shallow angle and the golden light lasts much longer.

Free, with a one-time Pro

Today, the Sun Dial and two saved places are free. SolarDial Pro, a one-time purchase, adds unlimited places, a shadow-length calculator and a daylight trend chart.
