445

Year 445 was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Valentinianus and Nomus. The denomination 445 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.
