Year 224 (CCXXIV) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Iulianus and Crispinus (or, less frequently, year 977 Ab urbe condita). The denomination 224 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.
