AD 73 (LXXIII) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Domitian and Messalinus (or, less frequently, year 826 Ab urbe condita). The denomination AD 73 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.
