Year 215 (CCXV) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Laetus and Sulla (or, less frequently, year 968 Ab urbe condita). The denomination 215 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.
