80

Year 80 (LXXX) was a leap year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Augustus and Domitianus (or, less frequently, year 833 Ab urbe condita). The denomination 80 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.
