Year '''304''' ('''[[Roman numerals|CCCIV]]''') was a [[leap year starting on Saturday]] of the [[Julian calendar]]. It was known in the [[Roman Empire]] as the '''Year of the Consulship of Diocletian and Maximian''' (or, less frequently, '''year 1057 ''[[Ab urbe condita]]'''''). The denomination 304 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.
