Year 434 (CDXXXIV) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aspar and Areobindus (or, less frequently, year 1187 Ab urbe condita). The denomination 434 for this year has been used since the early medieval period, when the Anno Dominicalendar era became the prevalent method in Europe for naming years.
