Year 47 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Calenius and Vatinius (or, less frequently, year 707 Ab urbe condita). The denomination 47 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.
