Year 27 BC was either a common year starting on Sunday, Monday or Tuesday or a leap year starting on Monday (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 Sunday of the Proleptic Julian calendar. At the time, it was known as the Year of the Second Consulship of Octavian and Agrippa (or, less frequently, year 727 Ab urbe condita).
