303 BC
Year 303 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Lentulus and Aventinensis (or, less frequently, year 451 "Ab urbe condita"). The denomination 303 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.
