Year **428 BC** was a year of the [pre-Julian Roman calendar](/source/Roman_calendar). At the time, it was known as the **Year of the Consulship of Cossus and Cincinnatus** or **Cincinnatus and Atratinus** (or, less frequently, **year 326 *[Ab urbe condita](/source/Ab_urbe_condita)***). The denomination 428 BC for this year has been used since the early medieval period, when the [Anno Domini](/source/Anno_Domini) [calendar era](/source/Calendar_era) became the prevalent method in Europe for naming years.
