History
Origins
The idea of numbering years beginning from the date then believed to be the
date of birth of Jesus, was conceived about 1,500 years ago by the Christian monk
Dionysius Exiguus. He did this to replace the then dominant
Era of Martyrs system, because he did not wish to continue the memory of a tyrant who persecuted Christians.
He numbered years from an initial reference date ("
epoch"), an event he referred to as the
Incarnation of Jesus.
Dionysius labeled the column of the table in which he introduced the new era as "''Anni Domini Nostri Jesu Christi''".
This way of numbering years became more widespread in Europe with its use by
Bede
Bede ( ; ang, Bǣda , ; 672/326 May 735), also known as Saint Bede, The Venerable Bede, and Bede the Venerable ( la, Beda Venerabilis), was an English monk at the monastery of St Peter and its companion monastery of St Paul in the Kingdom ...
in England in 731. Bede also introduced the practice of dating years before what he supposed was the year of birth of Jesus, and the practice of not using a
year zero. In 1422,

Era" to distinguish dates on the Ecclesiastic calendar in popular use from dates of the
regnal year, the year of the reign of a sovereign, typically used in national law. (The word 'vulgar' originally meant 'of the ordinary people', with no derogatory associations.)
The first known use of the Latin term occurred in a 1615 book by
Johannes Kepler.
Kepler uses it again, as , in a 1616 table of
ephemerides,
[ ] and again, as , in 1617.
[ * Translation of title (per 1635 English edition): ''New Ephemerids for the Celestiall Motions, for the Yeeres of the Vulgar Era 1617–1636''] A 1635 English edition of that book has the title page in English – so far, the earliest-found use of ''Vulgar Era'' in English.
[ ] A 1701 book edited by John LeClerc includes "Before Christ according to the Vulgar Æra, 6". A 1716 book in English by Dean
Humphrey Prideaux says, "before the beginning of the vulgar æra, by which we now compute the years from his incarnation." A 1796 book uses the term "vulgar era of the nativity".
The first known use of "Christian Era" appears as the Latin phrase on the title page of a 1584 theology book. In 1649, the Latin phrase appeared in the title of an English almanac. A 1652 ephemeris is the first instance found so far of the English use of "Christian Era".
The English phrase "Common Era" appears at least as early as 1708,
[ ] and in a 1715 book on astronomy it is used interchangeably with "Christian Era" and "Vulgar Era". A 1759 history book uses ''common æra'' in a generic sense, to refer to the common era of the Jews. The first use found so far of the phrase "before the common era" is in a 1770 work that also uses ''common era'' and ''vulgar era'' as synonyms, in a translation of a book originally written in German.

uses the terms ''vulgar era'' and ''common era'' synonymously (meaning not the regnal year). In 1835, in his book ''
Living Oracles'',
Alexander Campbell, wrote: "The vulgar Era, or Anno Domini; the fourth year of Jesus Christ, the first of which was but eight days", and also refers to the ''common era'' as a synonym for ''vulgar era'' with "the fact that our Lord was born on the 4th year before the vulgar era, called Anno Domini, thus making (for example) the 42d year from his birth to correspond with the 38th of the common era".

The phrase "common era", in
lower case, also appeared in the 19th century in a 'generic' sense, not necessarily to refer to the Christian Era, but to any system of dates in common use throughout a civilization. Thus, "the common era of the Jews", "the common era of the Mahometans", "common era of the world", "the common era of the foundation of Rome". When it did refer to the Christian Era, it was sometimes qualified, e.g., "common era of the Incarnation", "common era of the Nativity", or "common era of the birth of Christ".

United States
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. BCE/CE is used by the
College Board in its history tests,
and by the
Norton Anthology of English Literature. Others have taken a different approach. The US-based
History Channel uses BCE/CE notation in articles on non-Christian religious topics such as
Jerusalem and Judaism.
[;] The 2006 style guide for the Episcopal Diocese ''Maryland Church News'' says that BCE and CE should be used.
In June 2006, in the United States, the Kentucky State School Board reversed its decision to use BCE and CE in the state's new Program of Studies, leaving education of students about these concepts a matter of local discretion.
Australia
In 2011, media reports suggested that the BC/AD notation in Australian school textbooks would be replaced by BCE/CE notation. The change drew opposition from some politicians and church leaders. Weeks after the story broke, the
Australian Curriculum, Assessment and Reporting Authority denied the rumour and stated that the BC/AD notation would remain, with CE and BCE as an optional suggested learning activity.
Canada
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.

Rationales
Support
The use of CE in Jewish scholarship was historically motivated by the desire to avoid the implicit "Our Lord" in the abbreviation ''AD''. Although other aspects of dating systems are based in Christian origins, AD is a direct reference to
Jesus as Lord.

Opposition

Raimon Panikkar argued that the BCE/CE usage is the less inclusive option, since in his view they are still using the Christian calendar, forcing it on other nations.
In 1993, the English-language expert
Kenneth G. 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
