Cassius Dio(53.1) indicates that he took the title princeps senatus in 28 BC. However, he also states that Augustus "added five years to his own terms as princeps, since his ten-year period was about to expire (this was in the consulship of Publius and Gnaeus Lentulus [18 BC])" (54.12), meaning that his official tenure as princeps began in 27 BC.
Res GestaeI.7, "For ten years in succession I was one of the triumvirs for the re-establishment of the constitution. To the day of writing this [June/July AD 14] I have been princeps senatus for forty years."
