Year 53 (LIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Silanus and Antonius (or, less frequently, year 806 Ab urbe condita). The denomination 53 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.
