Question

How do you determine the angle of sunlight?

Answer 1

The U.S. Naval Observatory has an online tool to tabulate the position of the Sun (or Moon) during one day. The angle above the horizon is the altitude, and the angle around the horizon, measured clockwise from due north, is called the azimuth.

If you are a glutton for punishment, you can calculate it yourself.

Update by Lynn (March 11, 2003): One reader e-mailed us and suggested the Approximate Astronomical Positions site, which will calculate positions of the Sun, Moon, and planets. It also gives equations for many calculations and has links to sites explaining many of the calculations. This is another good place to look if you want to calculate things yourself.
