Year 129 (CXXIX) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Celsus and Marcellus (or, less frequently, year 882 Ab urbe condita). The denomination 129 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.
