The Azimuth Dial

This article describes the azimuth dial, a type of horizontal dial with a vertical style, derived from the equatorial dial formula. It explains that while a vertical style at the center of a horizontal circle cannot show time correctly throughout the year due to declination changes, projecting an equatorial circle onto a horizontal plane forms an ellipse for the hour lines. The article provides the formula for the shadow angle and suggests this as a useful project for understanding geometry and for practical marking in playgrounds or gardens.
