Year 30 BC was either a common year starting on Wednesday, Thursday or Friday or a leap year starting on Thursday (link will display the full calendar) of the Julian calendar (the sources differ, see leap year error for further information) and a common year starting on Wednesday of the Proleptic Julian calendar. At the time, it was known as the Year of the Consulship of Octavian and Crassus (or, less frequently, year 724 Ab urbe condita). The denomination 30 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.


By place

  • Possible date of composition of the Tirukkuṛaḷ, attributed to Thiruvalluvar.
  • First possible date for the invention of the wheelbarrow in history; as the 5th century Book of the Later Han states that the wife of the once poor and youthful imperial censor Bao Xuan of the Chinese Han dynasty helped him push a lu che back to his village during their feeble wedding ceremony, around this year.
