Year 336 (CCCXXXVI) was a leap year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Nepotianus and Facundus (or, less frequently, year 1089 Ab urbe condita). The denomination 336 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.
