Year 520 (DXX) was a leap year starting on Wednesday (link will display the full calendar) of the Julian calendar. In the Roman Empire, it was known as the Year of the Consulship of Rusticus and Vitalianus (or, less frequently, year 1273 Ab urbe condita). The denomination 520 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.
