Common Era

Last updated

Common Era or Current Era (CE) [1] is one of the notation systems for the world's most widely used calendar era. BCE (Before the Common Era or Before the Current Era) is the era before CE. BCE and CE are alternatives to the Dionysian AD and BC system. The Dionysian era distinguishes eras using AD (anno Domini, "[the] year of [the] Lord") [2] and BC ("before Christ"). Since the two notation systems are numerically equivalent, "2019 CE" corresponds to "AD 2019" and "400 BCE" corresponds to "400 BC". [2] [3] [4] [lower-alpha 1] Both notations refer to the Gregorian calendar (and its predecessor, the Julian calendar). The year-numbering system utilized by the Gregorian calendar is used throughout the world today, and is an international standard for civil calendars. [5]

A calendar era is the year numbering system used by a calendar. For example, the Gregorian calendar numbers its years in the Western Christian era. The instant, date, or year from which time is marked is called the epoch of the era. There are many different calendar eras such as Saka Era.

Anno Domini Western calendar era

The terms anno Domini (AD) and before Christ (BC) are used to label or number years in the Julian and Gregorian calendars. The term anno Domini is Medieval Latin and means "in the year of the Lord", but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "anno Domini nostri Jesu Christi", which translates to "in the year of our Lord Jesus Christ".

The Gregorian calendar is the most widely used civil calendar in the world. It is named after Pope Gregory XIII, who introduced it in October 1582. The calendar spaces leap years to make the average year 365.2425 days long, approximating the 365.2422-day tropical year that is determined by the Earth's revolution around the Sun. The rule for leap years is:

Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100, but these centurial years are leap years if they are exactly divisible by 400. For example, the years 1700, 1800, and 1900 are not leap years, but the year 2000 is.

Contents

The expression has been traced back to 1615, when it first appeared in a book by Johannes Kepler as the Latin usage annus aerae nostrae vulgaris, [6] [7] and to 1635 in English as "Vulgar [lower-alpha 2] Era". The term "Common Era" can be found in English as early as 1708, [8] and became more widely used in the mid-19th century by Jewish religious scholars. In the later 20th century, the use of CE and BCE was popularized in academic and scientific publications, and more generally by authors and publishers wishing to emphasize sensitivity to non-Christians, by not explicitly referencing Jesus as "Christ" and Dominus ("Lord") through use of the abbreviation [lower-alpha 3] "AD". [10] [11]

Johannes Kepler German mathematician, astronomer and astrologer

Johannes Kepler was a German astronomer, mathematician, and astrologer. He is a key figure in the 17th-century scientific revolution, best known for his laws of planetary motion, and his books Astronomia nova, Harmonices Mundi, and Epitome Astronomiae Copernicanae. These works also provided one of the foundations for Newton's theory of universal gravitation.

Jesus central figure of Christianity

Jesus, also referred to as Jesus of Nazareth and Jesus Christ, was a first-century Jewish preacher and religious leader. He is the central figure of Christianity and is widely described as the most influential person in history. Most Christians believe he is the incarnation of God the Son and the awaited Messiah (Christ) prophesied in the Old Testament.

<i>Christ</i> (title) messianic dimension of Jesus, biblical figure

In Christianity, Christ is a title for the saviour and redeemer who would bring salvation to the whole House of Israel. Christians believe Jesus is the Israelite messiah foretold in both the Hebrew Bible and the Christian Old Testament. Christ, used by Christians as both a name and a title, is synonymous with Jesus.

History

Origins

The year numbering system used with Common Era notation was devised by the Christian monk Dionysius Exiguus in the year 525 to replace the Era of Martyrs system, because he did not wish to continue the memory of a tyrant who persecuted Christians. [12] He attempted to number years from an initial reference date ("epoch"), an event he referred to as the Incarnation of Jesus. [12] [13] [14] Dionysius labeled the column of the table in which he introduced the new era as "Anni Domini Nostri Jesu Christi". [15]

Dionysius Exiguus was a 6th-century monk born in Scythia Minor. He was a member of a community of Scythian monks concentrated in Tomis, the major city of Scythia Minor. Dionysius is best known as the inventor of the Anno Domini (AD) era, which is used to number the years of both the Gregorian calendar and the (Christianised) Julian calendar. Some churches adopted his computus (calculation) for the dates of Easter.

Incarnation (Christianity)

In Christian theology, the doctrine of the incarnation holds that Jesus, the preexistent divine Logos and the second hypostasis of the Trinity, God the Son and Son of the Father, taking on a human body and human nature, "was made flesh" and conceived in the womb of Mary the Theotokos. The doctrine of the incarnation, then, entails that Jesus Christ is fully God and fully human, his two natures joined in hypostatic union.

Numbering years in this manner became more widespread in Europe with its usage by Bede in England in 731. Bede also introduced the practice of dating years before what he supposed was the year of birth of Jesus, [16] and the practice of not using a year zero. [lower-alpha 4] In 1422, Portugal became the last Western European country to switch to the system begun by Dionysius. [17]

Bede 7th and 8th-century Anglo-Saxon monk, writer, and saint

Bede, also known as Saint Bede, Venerable Bede, and Bede the Venerable, was an English Benedictine monk at the monastery of St. Peter and its companion monastery of St. Paul in the Kingdom of Northumbria of the Angles. Born on lands likely belonging to the Monkwearmouth monastery in present day Sunderland, Bede was sent there at the age of seven and later joined Abbot Ceolfrith at the Jarrow monastery, both of whom survived a plague that struck in 686, an outbreak that killed a majority of the population there. While he spent most of his life in the monastery, Bede travelled to several abbeys and monasteries across the British Isles, even visiting the archbishop of York and King Ceolwulf of Northumbria. He is well known as an author, teacher, and scholar, and his most famous work, Ecclesiastical History of the English People, gained him the title "The Father of English History". His ecumenical writings were extensive and included a number of Biblical commentaries and other theological works of exegetical erudition. Another important area of study for Bede was the academic discipline of computus, otherwise known to his contemporaries as the science of calculating calendar dates. One of the more important dates Bede tried to compute was Easter, an effort that was mired with controversy. He also helped establish the practice of dating forward from the birth of Christ, a practice which eventually became commonplace in medieval Europe. Bede was one of the greatest teachers and writers of the Early Middle Ages and is considered by many historians to be the single most important scholar of antiquity for the period between the death of Pope Gregory I in 604 and the coronation of Charlemagne in 800.

Portugal Republic in Southwestern Europe

Portugal, officially the Portuguese Republic, is a country located mostly on the Iberian Peninsula in southwestern Europe. It is the westernmost sovereign state of mainland Europe. It is bordered to the west and south by the Atlantic Ocean and to the north and east by Spain. Its territory also includes the Atlantic archipelagos of the Azores and Madeira, both autonomous regions with their own regional governments.

Western Europe region comprising the westerly countries of Europe

Western Europe is the region comprising the western part of Europe. Though the term Western Europe is commonly used, there is no commonly agreed-upon definition of the countries that it encompasses.

Vulgar Era

Johannes Kepler first used "Vulgar Era" to distinguish dates on the Christian calendar from the regnal year typically used in national law. Johannes Kepler 1610.jpg
Johannes Kepler first used "Vulgar Era" to distinguish dates on the Christian calendar from the regnal year typically used in national law.

The term "Common Era" is traced back in English to its appearance as "Vulgar Era" to distinguish dates on the Ecclesiastic calendar in popular use from dates of the regnal year, the year of reign of a sovereign, typically used in national law.

A regnal year is a year of the reign of a sovereign, from the Latin regnum meaning kingdom, rule.

The first use of the Latin term anno aerae nostrae vulgaris [lower-alpha 5] discovered so far was in a 1615 book by Johannes Kepler. [7] Kepler uses it again, as ab Anno vulgaris aerae, in a 1616 table of ephemerides, [18] and again, as ab anno vulgaris aerae, in 1617. [19] A 1635 English edition of that book has the title page in English – so far, the earliest-found usage of Vulgar Era in English. [20] A 1701 book edited by John LeClerc includes "Before Christ according to the Vulgar Æra, 6". [21] 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." [22] [23] A 1796 book uses the term "vulgar era of the nativity". [24]

In astronomy and celestial navigation, an ephemeris gives the positions of naturally occurring astronomical objects as well as artificial satellites in the sky at a given time or times. Historically, positions were given as printed tables of values, given at regular intervals of date and time. The calculation of these tables was one of the first applications of mechanical computers. Modern ephemerides are often computed electronically, from mathematical models of the motion of astronomical objects and the Earth. However, printed ephemerides are still produced, as they are useful when computational devices are not available.

Humphrey Prideaux Dean of Norwich

Humphrey Prideaux was an English churchman and orientalist, Dean of Norwich from 1702. His sympathies inclined to Low Churchism in religion and to Whiggism in politics.

The first so-far-discovered usage of "Christian Era" is as the Latin phrase annus aerae christianae on the title page of a 1584 theology book. [25] In 1649, the Latin phrase annus æræ Christianæ appeared in the title of an English almanac. [26] A 1652 ephemeris is the first instance so-far-found for English usage of "Christian Era". [27]

The English phrase "common Era" appears at least as early as 1708, [8] and in a 1715 book on astronomy is used interchangeably with "Christian Era" and "Vulgar Era". [28] A 1759 history book uses common æra in a generic sense, to refer to the common era of the Jews. [29] The first-so-far found usage 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. [30] The 1797 edition of the Encyclopædia Britannica uses the terms vulgar era and common era synonymously. [31] 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", [32] 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..." [33] The Catholic Encyclopedia (1909) in at least one article reports all three terms (Christian, Vulgar, Common Era) being commonly understood by the early 20th century. [34]

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", [35] [36] "the common era of the Mahometans", [37] "common era of the world", [38] "the common era of the foundation of Rome". [39] When it did refer to the Christian Era, it was sometimes qualified, e.g., "common era of the Incarnation", [40] "common era of the Nativity", [41] or "common era of the birth of Christ". [42]

An adapted translation of Common Era into pseudo-Latin as Era Vulgaris (in Latin this means Common Mistress) [43] was adopted in the 20th century by some followers of Aleister Crowley, and thus the abbreviation "e.v." or "EV" may sometimes be seen as a replacement for AD. [44]

History of the use of the CE/BCE abbreviation

Although Jews have their own Hebrew calendar, they often use the Gregorian calendar, without the AD prefix. [45] As early as 1825, the abbreviation VE (for Vulgar Era) was in use among Jews to denote years in the Western calendar. [46] Common Era notation has also been in use for Hebrew lessons for "more than a century".[ when? ] [47] Some Jewish academics were already using the CE and BCE abbreviations by the mid-19th century, such as in 1856, when Rabbi and historian Morris Jacob Raphall used the abbreviation in his book Post-Biblical History of The Jews. [48] [lower-alpha 6]

In general publications, in the 200 years between 1808 and 2008 the ratio of usage of BCE to BC has increased by about 20% and CE to AD by about 50%, primarily since 1980. [50]

Contemporary usage

Some academics in the fields of theology, education and history have adopted CE and BCE notation, although there is some disagreement. [51]

More visible uses of Common Era notation have recently surfaced at major museums in the English-speaking world. Furthermore, several style guides now prefer or mandate its usage. [52] Even some style guides for Christian churches prefer its use: for example, the Episcopal Diocese Maryland Church News. [53]

In the United States, the usage of the BCE/CE notation in textbooks is growing. [47] Some publications have moved over to using it exclusively. For example, the 2007 World Almanac was the first edition to switch over to the BCE/CE usage, ending a 138-year usage of the traditional BC/AD dating notation. It is used by the College Board in its history tests, [54] 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. [55]

In 2002, England and Wales introduced the BCE/CE notation system into the official school curriculum. [56]

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 discretion at the local level. [57] [58] [59]

Also in 2011, media reports suggested that the BC/AD notation in Australian school textbooks would be replaced by BCE/CE notation. [60] The story became national news and 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. [61]

Rationale

Support

The use of CE in Jewish scholarship was historically motivated by the desire to avoid the implicit "Our Lord" in the abbreviation AD.[ citation needed ] Although other aspects of dating systems are based in Christian origins, AD is a direct reference to Jesus as Lord. [62] [63]

Proponents of the Common Era notation assert that the use of BCE/CE shows sensitivity to those who use the same year numbering system as the one that originated with and is currently used by Christians, but who are not themselves Christian. [64]

Former United Nations Secretary-General Kofi Annan [65] has argued:

[T]he Christian calendar no longer belongs exclusively to Christians. People of all faiths have taken to using it simply as a matter of convenience. There is so much interaction between people of different faiths and cultures – different civilizations, if you like – that some shared way of reckoning time is a necessity. And so the Christian Era has become the Common Era. [66]

Adena K. Berkowitz, when arguing at the Supreme Court opted to use BCE and CE because "Given the multicultural society that we live in, the traditional Jewish designations – B.C.E. and C.E. – cast a wider net of inclusion". [67]

Opposition

Some oppose the Common Era notation for explicitly religious reasons. Because the BC/AD notation is based on the traditional year of the conception or birth of Jesus, some Christians are offended by the removal of the reference to him in era notation. [68] The Southern Baptist Convention supports retaining the BC/AD abbreviations. [69] Roman Catholic priest and writer on interfaith issues Raimon Panikkar argued that the BCE/CE usage is the less inclusive option as, in his view, using the designation BCE/CE is a "return... to the most bigoted Christian colonialism" towards non-Christians, who do not necessarily consider the time period following the beginning of the calendar to be a "common era". [70]

There are also secular concerns. English language expert Kenneth G. Wilson speculated 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." [71] The short lived French Republican Calendar, for example, began with the first year of the French First Republic and rejected the seven-day week (with its connections to the Book of Genesis) for a ten-day week.

According to a Los Angeles Times report, it was a student's use of BCE/CE notation, inspired by its use within Wikipedia, which prompted the teacher and politician Andrew Schlafly to found Conservapedia, a cultural conservative wiki. [72] One of its "Conservapedia Commandments" is that users must always apply BC/AD notation, since its sponsors perceive BCE/CE notation to "deny the historical basis" of the dating system. [73]

Conventions in style guides

The abbreviation BCE, just as with BC, always follows the year number. Unlike AD, which traditionally precedes the year number, CE always follows the year number (if context requires that it be written at all). [71] Thus, the current year is written as 2019 in both notations (or, if further clarity is needed, as 2019 CE, or as AD 2019), 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). The abbreviations are sometimes written with small capital letters, or with periods (e.g., "B.C.E." or "C.E."). [74] Style guides for academic texts on religion generally prefer BCE/CE to BC/AD. [75]

Similar conventions in other languages

In 1938 Nazi Germany, the use of this convention was also prescribed by the National Socialist Teachers League. [79]
However, it was soon discovered that many German Jews had been using the convention ever since the 18th century, and they found it ironic to see "Aryans following Jewish example nearly 200 years later". [76]

Notes

  1. ↑ Two separate systems that also do not use religious titles, the astronomical system and the ISO 8601 standard, do use a year zero. The year 1 BCE (identical to the year 1 BC) is represented as 0 in the astronomical system, and as 0000 in ISO 8601. Presently, ISO 8601 dating requires use of the Gregorian calendar for all dates, however, whereas astronomical dating and Common Era dating allow use of either the Gregorian or Julian calendars.
  2. ↑ From the Latin word vulgus , the common people — to contrast it with the regnal year system of dating used by the Government.
  3. ↑ AD is shortened from anno Domini nostri Jesu Christi ("in the year of Our Lord Jesus Christ"). [9]
  4. ↑ As noted in History of the zero, the use of zero in Western civilization was uncommon before the twelfth century.
  5. ↑ In Latin, Common Era is written as Aera Vulgaris. It also occasionally appears, in Latin declination, as æræ vulgaris, aerae vulgaris, aeram vulgarem, anni vulgaris, vulgaris aerae Christianae, and anni vulgatae nostrae aerae Christianas.
  6. ↑ The term common era does not appear in this book; the term Christian era [lowercase] does appear a number of times. Nowhere in the book is the abbreviation explained or expanded directly. [49]

Astronomical year numbering is based on AD/CE year numbering, but follows normal decimal integer numbering more strictly. Thus, it has a year 0; the years before that are designated with negative numbers and the years after that are designated with positive numbers. Astronomers use the Julian calendar for years before 1582, including the year 0, and the Gregorian calendar for years after 1582, as exemplified by Jacques Cassini (1740), Simon Newcomb (1898) and Fred Espenak (2007).

An era is a span of time defined for the purposes of chronology or historiography, as in the regnal eras in the history of a given monarchy, a calendar era used for a given calendar, or the geological eras defined for the history of Earth.

Year orbital period of the Earth around the Sun

A year is the orbital period of the Earth moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. The current year is 2019.

AD 1 Year

AD 1 (I), 1 AD or 1 CE is the epoch year for the Anno Domini calendar era. It was the first year of the Common Era (CE), of the 1st millennium and of the 1st century. It was a common year starting on Saturday or Sunday, a common year starting on Saturday by the proleptic Julian calendar, and a common year starting on Monday by the proleptic Gregorian calendar. In its time, year 1 was known as the Year of the Consulship of Caesar and Paullus, named after Roman consuls Gaius Caesar and Lucius Aemilius Paullus, and less frequently, as year 754 AUC within the Roman Empire. The denomination "AD 1" for this year has been in consistent use since the mid-medieval period when the anno Domini (AD) calendar era became the prevalent method in Europe for naming years. It was the beginning of the Christian/Common era. The preceding year is 1 BC; there is no year 0 in this numbering scheme. The Anno Domini dating system was devised in AD 525 by Dionysius Exiguus.

An epoch, for the purposes of chronology and periodization, is an instant in time chosen as the origin of a particular calendar era. The "epoch" serves as a reference point from which time is measured.

Year 1 BC was a common year starting on Friday or Saturday of the Julian calendar and a leap year starting on Thursday of the Proleptic Julian calendar. It is also a leap year starting on Saturday, in the Proleptic Gregorian calendar. At the time, it was known as the Year of the Consulship of Lentulus and Piso. The denomination 1 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. The following year is 1 AD in the widely used Julian calendar, which does not have a "year zero".

300 BC Year

Year 300 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Corvus and Pansa. The denomination 300 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. B.C.E is the abbreviation for before the Common/Current/Christian Era.

Thai solar calendar

The Thai solar calendar was adopted by King Chulalongkorn in 1888 CE as the Siamese version of the Gregorian calendar, replacing the Thai lunar calendar as the legal calendar in Thailand. Years are now counted in the Buddhist Era (B.E.): พุทธศักราช, พ.ศ., which is 543 years ahead of the Gregorian calendar.

Before Present (BP) years is a time scale used mainly in geology and other scientific disciplines to specify when events occurred in the past. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date of the age scale, reflecting the origin of practical radiocarbon dating in the 1950s. The abbreviation "BP" has alternatively been interpreted as "Before Physics"; that is, before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, making dating after that time likely to be unreliable.

The Era of the Martyrs, also known as the Diocletian era, is a method of numbering years used by the Church of Alexandria beginning in the 4th century AD and by the Coptic Orthodox Church of Alexandria from the 5th century to the present. Western Christians were aware of it but did not use it. It was named for the Roman Emperor Diocletian who instigated the last major persecution against Christians in the Empire. Diocletian began his reign 20 November 284 during the Alexandrian year that began on 1 Thoth, the Egyptian New Year, or 29 August 284, so that date was used as the epoch: year one of the Diocletian era began on that date. This era was used to number the year in Easter tables produced by the Church of Alexandria.

Anno Mundi calendar era

Anno Mundi, abbreviated as AM, or Year After Creation, is a calendar era based on the biblical accounts of the creation of the world and subsequent history. Two such calendar eras have seen notable use historically:

Shaka era historical calendar era

The Shaka era is a historical calendar era, corresponding to Julian year 78. It is commonly known in Indian languages as Shalivahana Śaka or RTGS: Mahasakkarat "Greater Era").

The Hijri year or era is the era used in the Islamic lunar calendar, which begins its count from the Islamic New Year in 622 CE. During that year, Muhammad and his followers migrated from Mecca to Yathrib. This event, known as the Hijra, is commemorated in Islam for its role in the founding of the first Muslim community (ummah).

The Holocene calendar, also known as the Holocene Era or Human Era (HE), is a year numbering system that adds exactly 10,000 years to the currently dominant numbering scheme, placing its first year near the beginning of the Holocene geological epoch and the Neolithic Revolution, when humans transitioned from a hunter-gatherer lifestyle to agriculture and fixed settlements. The year 2019 in the Holocene calendar is 12,019 HE. The HE scheme was first proposed by Cesare Emiliani in 1993.

Anno Lucis

Anno Lucis is a dating system used in Masonic ceremonial or commemorative proceedings, which is equivalent to the Gregorian year plus 4000. It is similar to Anno Mundi.

Year zero does not exist in the anno Domini system usually used to number years in the Gregorian calendar and in its predecessor, the Julian calendar. In this system, the year 1 BC is followed by AD 1. However, there is a year zero in astronomical year numbering and in ISO 8601:2004 as well as in all Buddhist and Hindu calendars.

Byzantine calendar

The Byzantine calendar, also called "Creation Era of Constantinople" or "Era of the World", was the calendar used by the Eastern Orthodox Church from c. 691 to 1728 in the Ecumenical Patriarchate. It was also the official calendar of the Byzantine Empire from 988 to 1453, and of Kievan Rus' and Russia from c. 988 to 1700. Since "Byzantine" is a historiographical term, the original name uses the noun "Roman" as it was how the Eastern Roman Empire continued calling itself.

The Sardica paschal table or Sardica document is a document from a Latin manuscript of the 7th/8th century AD. It is a copy in Latin translation of the creed of the Eastern Christian bishops attending the Council of Sardica who, fearing that their deliberations would be dominated by Western bishops, met separately at Philippopolis. Appended to the creed and anathemas is a table of Paschal full moon dates, given as dates in the Julian calendar, for the years 328 to 357, together with a list of dates of 14 Nisan in the Jewish calendar, also referred to the Julian calendar, for the years 328 to 343, the year of the Council. The calendrical information contained in the document has been used by scholars in tracing the history of the computus and of the Hebrew calendar.

The influence of western culture and scholarship upon the rest of the world in turn led to this system of dating becoming the most widely used one across the globe today. Many scholars in historical and religious studies in the West in recent years have sought to lessen the explicitly Christian meaning of this system without abandoning the usefulness of a single, common, global form of dating. For this reason the terms common era and before the common era, abbreviated as CE and BCE, have grown in popularity as designations. The terms are meant, in deference to non-Christians, to soften the explicit theological claims made by the older Latin terminology, while at the same time providing continuity with earlier generations of mostly western Christian historical research.

A.D. appears either before or after the number of the year... although conservative use has long preferred before only; B.C. always follows the number of the year.... Common era (C.E.) itself needs a good deal of further justification, in view of its clearly Christian numbering. Most conservatives still prefer A.D. and B.C. Best advice: don't use B.C.E., C.E., or A.C.E. to replace B.C. and A.D. without translating the new terms for the very large number of readers who will not understand them. Note too that if we do end by casting aside the A.D./B.C. convention, almost certainly some will argue that we ought to cast aside as well the conventional numbering system itself, given its Christian basis.
