"This handy tool provides a relatively simple method of determining solar geometry variables for architectural design, such as designing shading devices or locating the position of the sun relative to a particular latitude and time. The Sun Angle Calculator is a quick and accurate tool and has been used extensively by educators, researchers, and design professionals for the past 50 years."
