The terms “AD” and “BC” have roots in Christianity. “AD” is an abbreviation for the Christian era (Latin for “the year of the Lord”), specifically Jesus Christ. “BC” is an abbreviation for “before Christ”.
The system labels the year based on the traditional concept of When Jesus was born — “AD” indicates a few years after his birth, and “BC” indicates a year before his birth.
In English, “AD” usually comes before the year, so the translation of “AD2022” is read as “our Lord in 2022”. In recent years, BC/AD alternatives have attracted attention. Many publications use “CE” or “AD” and “BCE” or “Before Christ” to make the system more comfortable for non-Christians. Before explaining how and why the system was invented, let’s go back a bit to the historical context.
When was AD invented?
In the early Middle Ages, one of the most important calculations, and therefore one of the main motifs of European mathematical studies, was the question of when to celebrate Easter. The First Council of Nicaea in 325 AD decided that Easter would fall on the Sunday following the full moon. Spring Equinox. Computus (Latin for calculation) is the most important procedure for calculating this date, and the calculation was described in a document known as the Easter Table. At one of these tables, with AD 525, a monk named Dionysius Exigus (sometimes called Dennis the Lesser) of Scythia Minoru introduced the AD system. Brussels, article published in the 2002 edition of the journal Sacris Erudiri.
Dionysius never said how he set the date Birth of JesusHowever, according to the book by Alden Mochamer, professor emeritus of history at the University of California, San Diego, he could have estimated the date using the surviving works of early Christians such as Clement of Alexandria and Eusebius of Caesarea. ..Easter calculations and the origin of the Christian era“(Oxford, 2008) Dionysius tried to define AD 1 as the year of the birth of Jesus Christ, but he deviated from his estimate a few years ago, and modern estimates indicate that the birth of Christ was d around 4 BC Live Science previously reported that there was.
From Anno Diocletiani to Anno Domini
Diocletian devised an alternative to the Diocletian system, named after Diocletian, who was the Roman Emperor from 284 to 305 AD. This system used the years since Diocletian became emperor. Rome.. The first year of Diocletian’s Easter table, “Anno Domini 532”, will follow the year of “Anno Diocletiani 247”. Johns Hopkins University Project Muse..
Diocletian made special changes to eliminate the memory of Diocletian, who severely persecuted Christians. world history encyclopedia.. E. Glenhinson, retired professor of church history at the Southern Baptist Theological School in Louisville, Kentucky, wrote that the Diocretians edited, killed, or imprisoned many Christians and burned their churches and scriptures. to augment.Primitive Christianity: the origin of the dawn of the Middle Ages(Abingdon Press, 2010).
The addition of the BC component took place two centuries after Dionysius, when the Venerable Vedas of Northumbria published his “History of the British Church” in 731. Antonia Grandsden, a history reader from the University of Nottingham , wrote in his book. “Historical Writing in England: c. 500 to approx. 1307” (Routledge, 1997). With this work, the AD system caught the attention of more people and was extended to include pre-AD 1 years. Past years were back-calculated to indicate the number of years the event lasted product “before Jesus Christ” or “before Jesus Christ”.
Isn’t there a year zero?
As a digital concept, Bede’s updated system had no “year zero” zero It did not appear in Western Europe. “For Veda, who also does not know the number zero, the year before a year BC was a BC. There was no year zero. After all, there was no zero for Veda,” Charles said. Saif is his book “Zero: A Biography of Dangerous Ideas” (Penguin Books, 2000).
However, zero did it Existence; Our modern concept of zero was first published in 628 AD by Indian scholar Brahmagupta. This idea did not catch on in medieval Christian Europe from the 11th to 13th centuries.
Spread of AD and BC
The BC/AD system became popular in the 9th century after Holy Roman Emperor Charlemagne adopted a system of government dating from all over Europe.
By the 15th century, all of Western Europe had adopted the BC/AD system. The inclusion of the system was implicitly included in the 16th century introduction Gregorian calendar After that, it became an international standard in 1988 announced by the International Organization for Standardization. ISO 8601, Describes an internationally recognized method of representing dates and times.
Christian era and vulgar times
Alternate forms of “Before AD” and “AD” date back to 1715 and are used interchangeably with “vulgar times” in astronomy books. At that time, vulgarity meant “ordinary” rather than “gross”. The term “vulgar era” is even older and first appeared in Johannes Kepler’s 1615 book.
There are several reasons why some people and organizations have moved from AD to CE. This includes demonstrating the susceptibility of non-Christians to using this dating system. This also includes the fact that “AD” is probably inaccurate, as scholars generally believe that Christ was born some years before AD 1.
