Common Era

{{See also|Anno Domini}}

Around the year 525, the Christian monk Dionysius Exiguus devised the principle of taking the moment that he believed to be the date of the incarnation of Jesus to be the point from which years are numbered (the epoch) of the Christian ecclesiastical calendar.Doggett, L.E., (1992), [http://eclipse.gsfc.nasa.gov/SEhelp/calendars.html "Calendars"] in Seidelmann, P.K., The Explanatory Supplement to the Astronomical Almanac, Sausalito CA: University Science Books, 2.1{{cite book |page=[https://books.google.com/books?id=BW_1mt4oebQC&q=jesus+birth+year+before&pg=PA686 686]|title=The International Standard Bible Encyclopedia |first=Geoffrey W. |last=Bromiley |publisher=Wm. B. Eerdmans Publishing |year=1995 |isbn= 978-0-8028-3781-3}} Dionysius labeled the column of the table in which he introduced the new era as "{{Lang|la|Anni Domini Nostri Jesu Christi}}" (the years of our Lord Jesus Christ).{{rp|52}} He did this to replace the Era of the Martyrs system (then used for some Easter tables) because he did not wish to continue the memory of a tyrant who persecuted Christians.{{rp|50}}

This way of numbering years became more widespread in Europe, with its use by Bede in England in 731. Bede also introduced the practice of dating years before what he supposed to have been the year of birth of Jesus,{{efn|Bede wrote of the Incarnation of Jesus, but treated it as synonymous with birth. Blackburn, B & Holford-Strevens, L, (2003), The Oxford Companion to the Year, Oxford University Press, 778.}} without a year zero.{{efn|As noted in History of the zero, the use of zero in Western civilization was uncommon before the twelfth century.}}

The term "Common Era" is traced back in English to its appearance as "Vulgar Era" to distinguish years of the Anno Domini era, which was in popular use, from dates of the regnal year (the year of the reign of a sovereign) typically used in national law.{{Cite web| last = Weatherall| first = Claire| title = Library: Archival Skills: Historical dates| access-date = 21 September 2024| url = https://libguides.hull.ac.uk/archival-skills/historical-dates |website=University of Hull |date = 18 May 2023}} (The word 'vulgar' originally meant 'of the ordinary people', with no derogatory associations.)

Some academics in the fields of theology, education, archaeology and history have adopted CE and BCE notation despite some disagreement.See, for example, the Society for Historical Archaeology states in its more recent style guide "Do not use CE (common era), BP (before present), or BCE; convert these expressions to AD and BC."

In 2013, the Canadian Museum of Civilization (now the Canadian Museum of History) in Gatineau (opposite Ottawa), which had previously switched to BCE/CE, decided to change back to BC/AD in material intended for the public while retaining BCE/CE in academic content.[https://nationalpost.com/holy-post/museum-of-civilization-putting-the-christ-back-in-history-as-bc-and-ad-return "Museum of Civilization putting the 'Christ' back in history as BC and AD return"], by Sean Kilpatrick/The Canadian Press, National Post, 27 February 2013

The notation is in particularly common use in Nepal in order to disambiguate dates from the local (Indian or Hindu) calendar, Bikram or Vikram Sambat. Disambiguation is needed because the era of the Hindu calendar is quite close to the Common Era.

In 2002, an advisory panel for the religious education syllabus for England and Wales recommended introducing BCE/CE dates to schools,{{cite news|url=http://www.thisislondon.co.uk/news/article-531644-ad-and-bc-become-cebce.do |title=AD and BC become CE/BCE |date=9 February 2002 |access-date=5 February 2012 |url-status=dead |archive-url=https://web.archive.org/web/20111220120909/http://www.thisislondon.co.uk/news/article-531644-ad-and-bc-become-cebce.do |archive-date=20 December 2011 |work=This is London}} and by 2018 some local education authorities were using them.

In the United States, the use of the BCE/CE notation in textbooks was reported in 2005 to be growing. Some publications have transitioned to using it exclusively. For example, the 2007 World Almanac was the first edition to switch to BCE/CE, ending a period of 138 years in which the traditional BC/AD dating notation was used.

Adena K.

The continuing use of AD and BC is not only factually wrong but also offensive to many who are not Christians."

Critics note the fact that there is no difference in the epoch of the two systems—chosen to be close to the date of birth of Jesus.

Wilson speculated a slippery slope scenario in his style guide that, "if we do end by casting aside the AD/BC convention, almost certainly some will argue that we ought to cast aside as well the conventional numbering system [that is, the method of numbering years] itself, given its Christian basis."

The abbreviation BCE, just as with BC, always follows the year number. Unlike AD, which still often precedes the year number, CE always follows the year number (if context requires that it be written at all).{{cite book | title = Chicago Manual of Style | edition = 17th | isbn = 978-0-226-28705-8 | date = 2017 | publisher = University of Chicago Press | at = ¶ 9.34 }} Thus, the current year is written as {{CURRENTYEAR}} in both notations (or, if further clarity is needed, as {{CURRENTYEAR}} CE, or as AD {{CURRENTYEAR}}), and the year that Socrates died is represented as 399 BCE (the same year that is represented by 399 BC in the BC/AD notation).

• In Germany, Jews in Berlin seem to have already been using words translating to "(before the) common era" in the 18th century, while others like Moses Mendelssohn opposed this usage as it would hinder the integration of Jews into German society. The formulation seems to have persisted among German Jews in the 19th century in forms like {{lang|de|vor der gewöhnlichen Zeitrechnung}} (before the common chronology).{{lang|de|Allgemeine Zeitung des Judenthums.

• In Welsh, OC can be expanded to equivalents of both AD ({{lang|cy|Oed Crist}}) and CE ({{lang|cy|Oes Cyffredin}}); for dates before the Common Era, CC (traditionally, {{lang|cy|Cyn Crist}}) is used exclusively.
• In Russian since the October Revolution (1917) {{lang|ru|до н.э. (до нашей эры}}, lit. before our era) and {{lang|ru|н.э. (нашей эры,}} lit. of our era) are used almost universally. Within Christian churches {{lang|ru|до Р.Х./от Р.Х. (до/от Рождества Христова}}, i.e. before/after the birth of Christ, equivalent to {{langx|la|Ante Christum natum}}) remains in use.
• In Polish, "p.n.e." ({{lang|pl|przed naszą erą}}, lit. before our era) and "n.e." ({{lang|pl|naszej ery}}, lit. of our era) are commonly used in historical and scientific literature. {{lang|pl|Przed Chrystusem}} (before Christ) and {{lang|pl|po Chrystusie}} (after Christ) see sporadic usage, mostly in religious publications.
• In China, upon the foundation of the Republic of China, the Government in Nanking adopted the Republic of China calendar with 1912 designated as year 1, but used the Western calendar for international purposes. The translated term was {{lang-zh|西元}} ({{lang|zh|xī yuán}}, "Western Era"), which is still used in Taiwan in formal documents. In 1949, the People's Republic of China adopted {{lang|zh|公元}} ({{lang|zh|gōngyuán}}, "Common Era") for both internal and external affairs in mainland China. This notation was extended to Hong Kong in 1997 and Macau in 1999 (de facto extended in 1966) through Annex III of Hong Kong Basic Law and Macau Basic Law, thus eliminating the ROC calendar in these areas. BCE is translated into Chinese as {{lang|zh|公元前}} ({{lang|zh|gōngyuánqián}}, "Before the Common Era").
• In Czech, the "n. l." ({{lang|cs|našeho letopočtu}} which translates as of our year count) and "př. n. l." or "před n. l." ({{lang|cs|před naším letopočtem}} meaning before our year count) is used, always after the year number. The direct translation of AD ({{lang|cs|léta Páně}}, abbreviated as L. P.) or BC ({{lang|cs|před Kristem}}, abbreviated as př. Kr.) is seen as archaic.{{cite web |url=https://prirucka.ujc.cas.cz/?id=780|title=Jazyková příručka Ústavu pro jazyk český|access-date=15 May 2020}}

• In Danish, "f.v.t." ({{lang|da|før vor tidsregning}}, before our time reckoning) and "e.v.t." ({{lang|da|efter vor tidsregning}}, after our time reckoning) are used as BCE/CE are in English. Also commonly used are "f.Kr." ({{lang|da|før Kristus}}, before Christ) and "e.Kr." ({{lang|da|efter Kristus}}, after Christ), which are both placed after the year number in contrast with BC/AD in English.
• In Macedonian, the terms "п.н.е." (пред нашата ера "before our era") and "н.е." (наша ера "our era") are used in every aspect.{{cn|date=March 2023}}
• In Estonian, "e.m.a." ({{lang|et|enne meie ajaarvamist}}, before our time reckoning) and "m.a.j."

Also in use are terms "eKr" ({{lang|et|enne Kristust}}, before Christ) and "pKr" ({{lang|et|pärast Kristust}}, after Christ). In all cases, the abbreviation is written after the year number.
• In Finnish, "eaa." ({{lang|fi|ennen ajanlaskun alkua}}, before time reckoning) and "jaa." ({{lang|fi|jälkeen ajanlaskun alun}}, after the start of time reckoning) are used as BCE and CE, respectively. Also (decreasingly) in use are terms "eKr", ({{lang|fi|ennen Kristusta}}, before Christ) and "jKr". ({{lang|fi|jälkeen Kristuksen}}, after Christ). In all cases, the abbreviation is written after the year number.
