Calendar year

Image credit is listed at the end of this article.

100 (C) was a leap year starting on Wednesday of the Julian calendar, the 100th year of the Common Era (CE) and Anno Domini (AD) designations, the 100th year of the 1st millennium, the 100th and last year of the 1st century, and the 1st year of the 100s decade. As of the start of 100, the Gregorian calendar was 2 days behind the Julian calendar, which was the dominant calendar of the time.

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 Middle Ages, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

This year saw Pacores, the last king of the Indo-Parthian kingdom, ascend to the throne. In the Americas, the Moche culture developed around this time, and Teotihuacan, a major city at the centre of modern-day Mexico, reached a population of around 60,000-80,000.
