NOTOC Year 405 (CDV) was a common year starting on Sunday of the Julian calendar. At the time, it was known as the Year of the Consulship of Stilicho and Anthemius (or, less frequently, '*year 1158 *Ab urbe condita'''''). The denomination 405 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.
