The year 645 BC was a year of the pre-Julian Roman calendar. In the Roman Empire, it was known as year 109 Ab urbe condita . The denomination 645 BC 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.
