355

Year 355 (CCCLV) 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 Arbitio and Maesius (or, less frequently, year 1108 Ab urbe condita). The denomination 355 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.
