Year 283 (CCLXXXIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Carus and Carinus (or, less frequently, year 1036 Ab urbe condita). The denomination 283 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.
