Year 408 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Tribunate of Iullus, Ahala and Cossus (or, less frequently, year 346 Ab urbe condita). The denomination 408 BC for this year has been used since the early medieval period, when the Anno Dominicalendar era became the prevalent method in Europe for naming years.
