__NOTOC__
Year '''20 BC''' was either a [[common year starting on Wednesday]] or [[Common year starting on Thursday|Thursday]] or a [[leap year starting on Tuesday]], [[Leap year starting on Wednesday|Wednesday]] or [[Leap year starting on Thursday|Thursday]] of the [[Julian calendar]] (the sources differ, see [[Julian calendar#Leap year error|leap year error]] for further information) and a [[common year starting on Tuesday]] of the [[Proleptic Julian calendar]]. At the time, it was also known as the '''Year of the Consulship of Appuleius and Nerva''' (or, less frequently, '''year 734 ''[[Ab urbe condita]]'''''). The denomination 20 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.
