__NOTOC__
Year '''456''' ('''[[Roman numerals|CDLVI]]''') was a [[leap year starting on Sunday]] 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.
