AD 84

AD 84 (LXXXIV) was a leap year starting on Thursday of the Julian calendar. In the Roman Empire, it was known as the Year of the Consulship of Augustus and Sabinus (or, less frequently, year 837 Ab urbe condita). The denomination AD 84 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.
