525
Year 525 was a common year starting on Wednesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Probus and Philoxenus. The denomination 525 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. In this year, the monk Dionysius Exiguus proposed a calendar starting with the birth of Jesus, so this was the first time the year was designated AD. However, the system was not used in general until the reign of Charlemagne in the 9th century.
