Year 456 (CDLVI) was a leap 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 Avitus without colleague (or, less frequently, year 1209 Ab urbe condita). The denomination 456 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.
