Year 310 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Rullianus and Censorinus (or, less frequently, year 444 Ab urbe condita). The denomination 310 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.
