AD 120

"120 (year)" redirects here. For the year of the pre-Julian Roman calendar, see 120 BC.

Year 120 (CXX) was a leap year starting on Sunday (link will display the full calendar) 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.
