Year 412 (CDXII) was a leap year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known in Europe as the Year of the Consulship of Honorius and Theodosius (or, less frequently, year 1165 Ab urbe condita). The denomination 412 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.
