340
Calendar year
Year 340 (CCCXL) was a leap year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Acindynus and Valerius (or, less frequently, year 1093 Ab urbe condita). The denomination 340 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.
