Year 15 BC was either a common year starting on Tuesday, Wednesday or Thursday or a leap year starting on Wednesday (link will display the full calendar) of the Julian calendar (the sources differ, see leap year error for further information) and a common year starting on Monday of the Proleptic Julian calendar. At the time, it was known as the Year of the Consulship of Drusus and Piso (or, less frequently, year 739 Ab urbe condita). The denomination 15 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.
