Clarity, ingenuity, and a sense of observation are the qualities that a shepherd on Velika Planina must have had when he made (and used) a wooden pocket sundial.
From wood, he carved a palm-sized wooden board in the shape of a crescent moon. On it, he burnt notches in a semicircle to represent clocks and drilled 13 holes.
Into the middle hole he stuck a tiny stick, which casts a shadow in the sun along the board. Every 14 days he stuck the stick in a different hole to set the time.
He marked the morning time with Arabic numerals and the afternoon time with Roman.
Sundials were made and used until the Second World War.
