Year 228 (CCXXVIII) was a leap year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Modestus and Maecius (or, less frequently, year 981 Ab urbe condita). The denomination 228 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.
