Year 531 (DXXXI) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year after the Consulship of Lampadius and Probus (or, less frequently, year 1284 Ab urbe condita). The denomination 531 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.
