398

Year 398 (CCCXCVIII ) was a common year starting on Friday of the Julian calendar, the 395th Year of the Common Era (CE) and Anno Domini (AD) designations, the 398th year of the 1st millennium, the last 3 years of the 4th century, and the 9th and pre-final year of the 390s decade. At the time, it was known as the Year of the Consulship of Augustus and Eutychianus (or, less frequently, year 1151 Ab urbe condita ). The denomination 398 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.
