AD 69

AD 69 (LXIX) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. In the Roman Empire, it was known as the Year of the consulship of Galba and Vinius (or, less frequently, year 822 Ab urbe condita). The denomination AD 69 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.
