AD 27 (XXVII) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Piso and Frugi (or, less frequently, year 780 Ab urbe condita). The denomination AD 27 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.
