Year 142 (CXLII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known in the Roman Empire as the Year of the Consulship of Pactumeius and Quadratus (or, less frequently, year 895 Ab urbe condita). The denomination 142 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.
