How sundials work.
Short, technical articles that take a curious reader from “a shadow tells time” to the angles that make a working dial on your wall.
How Vertical Sundials Work
Wall declination, style height, substyle distance — the geometry that makes every wall sundial unique, explained without jargon.
Reading a Sundial
Why a sundial reads different from your phone — longitude, the Equation of Time, and how the two corrections combine to convert sundial time into wall-clock time.
Sun Mechanics
Why the sun moves the way it does — Earth's rotation, its tilted axis, and the three small facts of astronomy that everything in sundial design is built on.
What Is a Sundial?
The oldest precision instrument still in daily use. How a shadow, a surface, and some geometry tell time — no batteries, no gears, no moving parts.
