The definitive guide to sundials is also a handy reference for charting the path of the sun. This book explains all you need to know about how to use the position of the sun to tell time. This is actually a fairly complicated business involving time zones, the equation of time, and daylight saving time. Learn how to chart an analemma on the floor of your own house - so the sun will tell you not only the time of day, but the day of the year as well! A very good read.
