Year '''340''' ('''[[Roman numerals|CCCXL]]''') was a [[leap year starting on Tuesday]] of the [[Julian calendar]]. At the time, it was known as the '''Year of the Consulship of Acindynus and Valerius''' (or, less frequently, '''year 1093 ''[[Ab urbe condita]]'''''). The denomination 340 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.
