302

Year 302 (CCCII) was a common year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Constantius and Valerius or, less frequently, year 1055 Ab urbe condita. The denomination 302 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. Events
