Year 39 BC was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Censorinus and Sabinus (or, less frequently, year 715 Ab urbe condita). The denomination 39 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.
