Year 117 (CXVII) 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 Niger and Apronianus (or, less frequently, year 870 Ab urbe condita). The denomination 117 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.
