Year 313 (CCCXIII) was a common year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Constantinus and Licinianus (or, less frequently, year 1066 Ab urbe condita). The denomination 313 for this year has been used since the early medieval period, when the Anno Dominicalendar era became the prevalent method in Europe for naming years. This year is notable for ending of the persecution of Christians in the Roman Empire.
