280



Year 280 (CCLXXX) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Messalla and Gratus (or, less frequently, year 1033 Ab urbe condita). The denomination 280 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.
