The year 285 (CCLXXXV) was a common year starting on Thursday (link will display the full calendar) of the Julian calendar. In the Roman Empire, it was known as the "Year of the Consulship of Carinus and Aurelius" (or, less frequently, "year 1038 Ab urbe condita"). The denomination 285 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.
