Year 308 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Mus and Rullianus (or, less frequently, year 446 Ab urbe condita). The denomination 308 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.
