__NOTOC__
Year '''320''' ('''[[Roman numerals|CCCXX]]''') was a [[leap year starting on Friday]] of the [[Julian calendar]]. 

At the time, it was known as the '''Year of the Consulship of Constantinus and Constantinus''' (or, less frequently, '''year 1073 ''[[Ab urbe condita]]'''''). The denomination 320 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.
