286



Year 286 (CCLXXXVI) 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 Maximus and Aquilinus (or, less frequently, year 1039 Ab urbe condita). The denomination 286 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.
