29 BC

Year 29 BC was either a common year starting on Friday or Saturday or a leap year starting on Thursday, Friday or Saturday (link will display the full calendar) of the Julian calendar (the sources differ, see leap year error for further information) and a leap year starting on Thursday of the Proleptic Julian calendar. At the time, it was known as the Year of the Consulship of Octavian and Appuleius (or, less frequently, year 725 Ab urbe condita). The denomination 29 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.
