Year 154 (CLIV) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Lateranus (or, less frequently, year 907 Ab urbe condita). The denomination 154 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.
