Year 7 BC was a common year starting on Saturday or Sunday of the Julian calendar (the sources differ, see leap year error for further information) and a common year starting on Thursday of the Proleptic Julian calendar. In the Roman world, it was known as the Year of the Consulship of Tiberius and Piso (or, less frequently, year 747 Ab urbe condita). The denomination 7 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.
