365 BC

Year 365 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Aventinensis and Ahala (or, less frequently, year 389 Ab urbe condita). The denomination 365 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
