Year 800 (DCCC) was a leap year starting on Wednesday (link will display the full calendar) of the Julian calendar, the 800th year of the Common Era (CE) and Anno Domini (AD) designations, the 800th year of the 1st millennium, the 100th and last year of the 8th century, and the 1st year of the 800s decade. It was around this time that the Anno Domini calendar era became the prevalent method in Europe for naming years, so from this time on, the years began to be known as 800 and onwards.
