Year 477 (CDLXXVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year after the Consulship of Basiliscus and Armatus (or, less frequently, year 1230 Ab urbe condita). The denomination 477 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.
