How they kept time eight thousand years ago


The oldest pocket calendar in the world, about 8.000 years old, was found at the archaeological site of Medvednjak, near Smederevska Palanka in Šumadija.

The calendar was made using a wild boar’s tusks. In its outer part there are 28 miniature triangular indentations carved on the inside. This corresponds to a month cycle of 28 days with four distinctive moon phases and suggests that the tusks were used to denote a lunar calendar.


At the beginning of 2017, in the organization of Kovionica Cultural Park, the Medvednjak calendar was reconstructed using marble.
