388

Year 388 (CCCLXXXVIII ) was a leap year starting on Saturday of the Julian calendar. At the time, it was known as the Year of the Consulship of Augustus without colleague (or, less frequently, year 1141 Ab urbe condita ). The denomination 388 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.
