In the early Middle Ages, the most important calculation, and thus one of the main motivations for the European study of mathematics, was the problem of when to celebrate Easter. The First Council of Nicaea, in A.D. 325, had decided that Easter would fall on the Sunday following the full moon that follows the springequinox. Computus (Latin for comp...
Dionysius devised his system to replace the Diocletian system, named after Diocletian who was Roman Emperor from A.D. 284 to A.D. 305. This system used the number of years since Diocletian became the emperor of Rome. The first year in Dionysius' Easter table, "Anno Domini 532," followed the year "Anno Diocletiani 247," according to Johns Hopkins Un...
The addition of the B.C. component happened two centuries after Dionysius, when the Venerable Bede of Northumbria published his "Ecclesiastical History of the English People" in 731, wrote Antonia Gransden, who was a reader in history at the University of Nottingham, in her book "Historical Writing in England: c. 500 to c. 1307" (Routledge, 1997). ...
There was no "year zero" in Bede's updated system, as the concept of the number zerohad not appeared in Western Europe. "To Bede, also ignorant of the number zero, the year that came before 1 A.D. was 1 B.C. There was no year zero. After all, to Bede, zero didn't exist," wrote Charles Seife in his book "Zero: The Biography of a Dangerous Idea" (Pen...
The B.C./A.D. system became more popular in the ninth century after Holy Roman Emperor Charlemagneadopted the system for dating acts of government throughout Europe. By the 15th century, all of Western Europe had adopted the B.C./A.D. system. The system's inclusion was implicit in the 16th-century introduction of the Gregorian calendar and it later...
The alternative form of "Before the Common Era" and "Common Era" dates back to 1715, where it is used in an astronomy book interchangeably with "Vulgar Era." At the time, vulgar meant "ordinary," rather than "crude." The term "Vulgar Era" is even older, first appearing in a 1615 book by Johannes Kepler. There are a number of reasons why some indivi...

One of the early writers to date this way was Dionysius Exiguus, a monk who, in 525 A.D., was intent on working out when exactly Easter would occur in the coming years.
Nov 8, 2023 · AD stands for Anno Domini. Anno is Latin for “in the year,” domini is Latin for “lord,” so Anno Domini translates as “in the year of our Lord.” Since Christianity maintains that Jesus is still living—ascended to heaven, at the father’s right hand—every year since his birth is a year of our Lord.
The earliest documented use of this method of reckoning the date is in the work of Bede in the seventh century, but the system originated with an eastern monk named Dionysius Exiguus in the year 525.
