How it works?
If you want to make Human sundial at your location, we can provide easy to follow calculations for such a sun clock, that when laid out on the ground, a person stands on the current month and their shadow cast on the ground tells the time.

a) Precise, step-by-step instructions how to „transfer“ layout plan on the ground, written in a way that 12-year old children can follow it without any problems.
