Later, in the 7th century, the Byzantines adopted a different Anno Mundi system based on the year 5509 B. In fact, modern historians use AUC much more frequently than the Romans themselves did.
The dominant method of identifying Roman years in Roman times was to name the two consuls who held office that year."@Mark they did not use it in context of naming years from a short interval, close to the current time.
But they used for instance, to describe years distant enough so that people do not remember the consuls.
In a sense, Anno Domini is simply an extension of this, counting years of the "reign" of Jesus Christ.If the Anno Domini system hadn't been adopted, the United States might refer to the current date as "December 13 of the sixth year of the Obama Presidency", while the British would describe it as "December 13 of the 62nd year of the reign of Elizabeth II".(This answer-comment was originally posted as a comment when the post was locked and no open for questions.) The use of Anno Domini ("in the year of our Lord") was first used in narrative history by Bede (although it had been used very slightly in some annals before that).Before Bede's use of it, there was no use of a year number in everyday use in western Europe. The normal mode of specifying the year before that time (8th century) was by regnal years, or consular years (Rome), or Judges/Archons/Olympiads (Greece).Note that ancient historians sometimes used the Era of Nabonassar to do synchronisms.
When Rome collapsed and the consular dates no longer could be used, the Eastern (Byzantine) Empire adopted at first the era Anno Mundi beginning on 25 March 5493 BC, developed by scholars in Alexandria around 200 A.
D., and now known as the "Alexandrian Era." Anno Mundi ("year of the world") posits a "date of creation" going forward from Adam and Eve. From your very own link: "Renaissance editors sometimes added AUC to Roman manuscripts they published, giving the false impression that the Romans usually numbered their years using the AUC system.
D.) year numbering, sometimes secularized as "BCE" (Before Common Era) or "CE" (Common Era). For example, both Jews and Muslims maintain a calendar which is not related to CE; many cultures maintain a calendar which "begins" with the foundation of their government or the reign of the current dynasty.
What was the prevailing method of dating years in Western culture before this system came into use? The use of Anno Domini ("in the year of our Lord") was first used in narrative history by Bede (although it had been used very slightly in some annals before that).
It was invented, more or less, by Dionysus Exiguus (circa 470 – 544).
