Details the construction of the large 30-foot diameter horizontal dial with a 20-foot stainless-steel gnomon, created for the Queen’s Diamond Jubilee. To ensure public utility, the hour lines were designed to allow for longitude, making the dial read close to clock time, despite the resulting asymmetry.

This article presents a design for a horizontal sundial adjustable for the Equation of Time and longitude by rotation around an axis parallel to the gnomon's style-edge. The design features a dial-face and gnomon-spine on a head, connected to a base with scales for longitude and a twelve-month Equation of Time adjustment. The offset bearing configuration and a Vernier-like scale simplify operations, allowing users to set the dial for different longitudes and regular Equation of Time corrections.

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.
