Dan The best way to test your sundial in in Sketchup itself. Turn on shadows and set the time and date. I have carefully checked the Sketchup routines and they correctly reflect the sun's actual altitude and azimuth. So you can track all the effects of the Equation of Time, Longitude Offset, etc Best wishes Kevin
