Year 23 BC was either a common year starting on Saturday or Sunday or a leap year starting on Friday, Saturday or Sunday (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 Friday of the Proleptic Julian calendar. At the time, it was known as the Year of the Consulship of Augustus and Varro (or, less frequently, year 731 Ab urbe condita). The denomination 23 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.
