325

This article is about the year 325. For the number, see 325 (number).

Year 325 (CCCXXV) was a common year starting on Friday of the Julian calendar. At the time, it was known as the Year of the Consulship of Proculus and Paulinus (or, less frequently, year 1078 Ab urbe condita). The denomination 325 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.
