SunCalc
Shows the sun's position, azimuth, elevation and shadow length for any location, date and time on a map. A core tool for chronolocating photos and video.

field note
Measure a shadow's direction and its length relative to the object casting it, then drag the time slider until SunCalc's shadow line matches. You get a tight time-of-day estimate, and a rough season when the location is known.
