Year 309 (CCCIX) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. In the Roman Empire, it was known as the Year of the Consulship of Licinianus and Constantius[1] (or, less frequently, year 1062 Ab urbe condita). The denomination 309 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.
