Year 35 BC was either a common year starting on Thursday or Friday or a leap year starting on Wednesday, Thursday or Friday of the Julian calendar (the sources differ, see leap year error for further information)[citation needed] and a common year starting on Thursday of the Proleptic Julian calendar. At the time, it was known as the Year of the Consulship of Cornificius and Sextus (or, less frequently, year 719 Ab urbe condita). The denomination 35 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.
