The Byzantine Timepiece offers a unique way to experience timekeeping, inspired by ancient practices predating the Byzantine Empire. This application allows users to pray and organize their day following the tradition of unequal hours, similar to how it was done by King David and the Apostles.

Originating from Ancient Judeans, Byzantine Time diverges from modern clocks by starting the next day at evening instead of midnight. To operate, the app requires GPS or manual input of longitude and latitude in the settings. This timekeeping method is still observed by Holy Monks on Mount Athos in Greece and maintained by the Eastern Orthodox Church for their Prayer Hours.
