Year 273 (CCLXXIII) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Tacitus and Placidianus (or, less frequently, year 1026 Ab urbe condita). The denomination 273 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.
