312 BC

Year 312 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Corvus and Mus (or, less frequently, year 442 Ab urbe condita). The denomination 312 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.
