Year 364 (CCCLXIV) was a leap year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Augustus and Varronianus (or, less frequently, year 1117 Ab urbe condita). The denomination 364 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.
