Year 327 (CCCXXVII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known in Rome as the Year of the Consulship of Constantius and Maximus (or, less frequently, year 1080 Ab urbe condita). The denomination 327 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.
