Year '''142''' ('''[[Roman numerals|CXLII]]''') was a [[common year starting on Sunday]] 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.
