The article presents the results of interdisciplinary research made with the
help of archaeological, physical and astronomical methods. The aim of the study
were analysis and interpretation corolla marks of the vessel of the Late Bronze
Age, belonging to Srubna culture and which was found near the Staropetrovsky
village in the northeast of the Donetsk region (Central Donbass). Performed
calculations and measurements revealed that the marks on the corolla of
Staropetrovsky vessel are marking of horizontal sundial with a sloping gnomon.
Several marks on the corolla of the vessel have star shape. Astronomical
calculations show that their position on the corolla, as on "dial" of watch,
indicates the time of qualitative change the visibility of Sirius in the day
its heliacal rising and the next few days in the Late Bronze Age at the
latitude of detection of Staropetrovsky vessel. Published in the article the
results of astronomical calculations allow to state that astronomical year in
the Srubna tradition began with a day of heliacal rising of Sirius. Vessel,
