The republican dates given to the right are those of the [[Varronian chronology]]; that is, those calculated by the scholar, [[Marcus Terentius Varro]]. His republic begins in the year 510/509 BC by modern calculation. These were the official imperial dates. Many other dates and chronologies existed, notably those of [[Livy]], with which the emperor must have been familiar, but he did not forbid their use in unofficial contexts. The AUC chronology does not exactly correspond; it is later than the Varronian by a year. [[Censorinus]], who went over Varro's calculations, he says, explains that Ulpius and Pontianus were consuls in the 1014th year from the re-founding of the [[Olympic games]] (776 BC); that is, [[Olympiad]] 254.2 (second year of the 254th Olympiad) and that this year was AUC 991, starting by modern calculations January 1, 238 AD. Varro's AUC 1 therefore was 754/753 BC.<ref>Greswell (1854), pp. 31-32.</ref> The identities of Ulpius and Pontianus remain a mystery, as they are only named by Censorinus, but the names are irrelevant to the argument. The republic began in Varro's view in {{auc|245|AUC|alinks=off}}.

[[Gaius Julius Solinus|Solinus]] observed that Gaius Pompeius Gallus and [[Quintus Veranius|Quintus Verranius]] were consuls in Olympiad 207.1, and that this year was 801 AUC, counting from the foundation of Rome at Olympiad 7.1. By modern calculation this is 49 AD. He was relying on the official dating scheme, which must have been the ''fasti consulares''. In Varro's chronology this is AUC 802. Simple subtraction shows that AUC 1 in Augustus' fasti is 753/752 BC. The fasti give to the start of the republic a date of {{auc|244|AUC|alinks=off}}, but some editors "correct" all the AUC to Varronian. Similarly the fasti run to the death of Augustus in 13 AD (14 in the Varronian). This is not a difference in the starting date of the republic or the year of Augustus' death, which remain in the same years relative to surrounding events in either case; instead, the year of AUC 1 differs.<ref>Greswell (1854), pp. 36-43.</ref>
