Year 19 (XIX) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Silanus and Balbus (or, less frequently, year 772 Ab urbe condita). The denomination 19 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.
