__NOTOC__
Year '''28 BC''' was either a [[common year starting on Saturday]], [[Common year starting on Sunday|Sunday]] or [[Common year starting on Monday|Monday]] or a [[leap year starting on Saturday]] or [[Leap year starting on Sunday|Sunday]] 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 Saturday]] of the [[Proleptic Julian calendar]]. At the time, it was known as the '''Year of the First Consulship of Octavian and Agrippa''' (or, less frequently, '''year 726 ''[[Ab urbe condita]]'''''). The denomination 28 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.
