The eastern hemisphere in 100 AD

The world in 100

Year 100 (C) was a leap year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Traianus and Frontinus (or, less frequently, year 853 Ab urbe condita). The denomination 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.
