__NOTOC__
Year '''45 BC''' was either a [[common year starting on Thursday]], [[Common year starting on Friday|Friday]] or [[Common year starting on Saturday|Saturday]] or a [[leap year starting on Friday]] or [[Leap year starting on Saturday|Saturday]] (the sources differ, see [[Julian calendar#Leap year error|leap year error]] for further information) and the first year of the [[Julian calendar]] and a [[leap year starting on Friday]] of the [[Proleptic Julian calendar]]. At the time, it was known as the '''Year of the Consulship of Caesar without Colleague''' (or, less frequently, '''year 709 ''[[Ab urbe condita]]'''''). The denomination 45 BC 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.
