__NOTOC__
Year '''364''' ('''[[Roman numerals|CCCLXIV]]''') was a [[leap year starting on Thursday]] of the [[Julian calendar]]. At the time, it was known as the '''Year of the Consulship of Augustus and Varronianus''' (or, less frequently, '''year 1117 ''[[Ab urbe condita]]'''''). The denomination 364 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.<ref>{{Cite journal |last=Wacholder |first=Ben Zion |date=2001 |title=Calendar Wars Between the 364 and the 365-Day Year |url=https://www.jstor.org/stable/24663055 |journal=Revue de Qumrân |volume=20 |issue=2 (78) |pages=207–222 |jstor=24663055 |issn=0035-1725}}</ref><ref>{{Cite journal |last=ZADOK |first=Ran |date=1989-01-01 |title=Notes on the Historical Geography of Mesopotamia and Northern Syria |url=http://dx.doi.org/10.2143/anes.27.0.2012496 |journal=Ancient Near Eastern Studies |volume=27 |pages=154–169 |doi=10.2143/anes.27.0.2012496 |issn=1378-4641|url-access=subscription }}</ref>
