AD 100
AD 100 (C) was a leap year starting on Wednesday (link will display the full calendar) of the Julian calendar. In the Roman Empire, it was sometimes referred to as year 853 "ab urbe condita", i.e., 853 years since the founding of Rome in 753 B.C. The denomination AD 100 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.
