Year '''120''' ('''[[Roman numerals|CXX]]''') was a [[leap year starting on Sunday]] of the [[Julian calendar]]. At the time, it was known as the '''Year of the Consulship of Severus and Fulvus''' (or, less frequently, '''year 873 ''[[Ab urbe condita]]'''''). The denomination 120 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.
