AD 71

AD 71 (LXXI) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Vespasian and Nerva (or, less frequently, year 824 Ab urbe condita). The denomination AD 71 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.
