AD 78 (LXXVIII) was a common year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Novius and Commodus (or, less frequently, '*year 831 *Ab urbe condita'''''). The denomination AD 78 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.
