Year 263 (CCLXIII) 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 Albinus and Dexter (or, less frequently, year 1016 Ab urbe condita). The denomination 263 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.
