Byzantine time system of the Serbian monastery Hilandar: And the whole Mount Athos

Mount Athos uses Byzantine time system, where hours are counted from sunset. Setting the clock to Eastern European Time is done with tables printed in the church calendar every year. Having determined that these tables correspond to Athens, this paper calculates tables for Hilandar Monastery, which is very important for the history of timekeeping of the Serbs. Mount Athos monasteries are concentrated in a small area, differences in local times are negligible, and so they can all use the Hilandar table
