Common Era

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 BC and AD system respectively. 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][a] 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]

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[b] 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[c] "AD".[10][11]

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]

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.[d] In 1422, Portugal became the last Western European country to switch to the system begun by Dionysius.[17]

Vulgar Era

Johannes Kepler 1610
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.

The first use of the Latin term anno aerae nostrae vulgaris[e] 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]

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".[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][f]

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. 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 Germany, Jews in Berlin seem to have already been using "(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.[76] The formulation seems to have persisted among German Jews in the 19th century in forms like vor der gewöhnlichen Zeitrechnung (before the common chronology).[77][78] 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 Time magazine found it ironic to see "Aryans following Jewish example nearly 200 years later".[76]
  • In Spanish, common forms used for "BC" are aC and a. de C. (for "antes de Cristo", "before Christ"), with variations in punctuation and sometimes the use of J.C. (Jesucristo) instead of C. In scholarly writing, AEC is the equivalent of the English "BCE", "antes de la Era Común" or "Before the Common Era".[80]
  • In Welsh, OC can be expanded to equivalents of both AD (Oed Crist) and CE (Oes Cyffredin); for dates before the Common Era, CC (traditionally, Cyn Crist) is used exclusively, as Cyn yr Oes Cyffredin would abbreviate to a mild obscenity.[81]

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]

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.

1 BC

Year 1 BC was a common year starting on Friday or Saturday (link will display the full calendar) of the Julian calendar (the sources differ, see leap year error for further information) 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 (or, less frequently, year 753 Ab urbe condita). 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".

AD 1

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 (ab urbe condita) 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.

The Julian calendar, a 45 BC reform of the Roman calendar, was the calendar used by Rome in AD 1.

Anno Domini

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".

This calendar era is based on the traditionally reckoned year of the conception or birth of Jesus of Nazareth, with AD counting years from the start of this epoch, and BC denoting years before the start of the era. There is no year zero in this scheme, so the year AD 1 immediately follows the year 1 BC. This dating system was devised in 525 by Dionysius Exiguus of Scythia Minor, but was not widely used until after 800.The Gregorian calendar is the most widely used calendar in the world today. For decades, it has been the unofficial global standard, adopted in the pragmatic interests of international communication, transportation, and commercial integration, and recognized by international institutions such as the United Nations.Traditionally, English followed Latin usage by placing the "AD" abbreviation before the year number. However, BC is placed after the year number (for example: AD 2019, but 68 BC), which also preserves syntactic order. The abbreviation is also widely used after the number of a century or millennium, as in "fourth century AD" or "second millennium AD" (although conservative usage formerly rejected such expressions). Because BC is the English abbreviation for Before Christ, it is sometimes incorrectly concluded that AD means After Death, i.e., after the death of Jesus. However, this would mean that the approximate 33 years commonly associated with the life of Jesus would neither be included in the BC nor the AD time scales.Terminology that is viewed by some as being more neutral and inclusive of non-Christian people is to call this the Current or Common Era (abbreviated as CE), with the preceding years referred to as Before the Common or Current Era (BCE). Astronomical year numbering and ISO 8601 avoid words or abbreviations related to Christianity, but use the same numbers for AD years.

Astronomical year numbering

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).The prefix AD and the suffixes CE, BC or BCE (Common Era, Before Christ or Before Common Era) are dropped. The year 1 BC/BCE is numbered 0, the year 2 BC is numbered −1, and in general the year n BC/BCE is numbered "−(n − 1)" (a negative number equal to 1 − n). The numbers of AD/CE years are not changed and are written with either no sign or a positive sign; thus in general n AD/CE is simply n or +n. For normal calculation a number zero is often needed, here most notably when calculating the number of years in a period that spans the epoch; the end years need only be subtracted from each other.

The system is so named due to its use in astronomy. Few other disciplines outside history deal with the time before year 1, some exceptions being dendrochronology, archaeology and geology, the latter two of which use 'years before the present'. Although the absolute numerical values of astronomical and historical years only differ by one before year 1, this difference is critical when calculating astronomical events like eclipses or planetary conjunctions to determine when historical events which mention them occurred.

Calendar era

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 Coptic Orthodox and Ethiopian Orthodox churches have their own Christian eras). 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.

In antiquity, regnal years were counted from the accession of a monarch. This makes the Chronology of the ancient Near East very difficult to reconstruct, based on disparate and scattered king lists, such as the Sumerian King List and the Babylonian Canon of Kings. In East Asia, reckoning by era names chosen by ruling monarchs ceased in the 20th century except for Japan, where they are still used.

Entheogenic drugs and the archaeological record

Entheogenic drugs have been used by various groups for thousands of years. There are numerous

historical reports as well as modern, contemporary reports of indigenous groups using entheogens, chemical substances used in a religious, shamanic, or spiritual context.

Epoch

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.

The moment of epoch is usually decided by congruity (makes simple sense), or by following conventions understood from the epoch in question. The epoch moment or date is usually defined from a specific, clear event of change, epoch event. In a more gradual change, a deciding moment is chosen when the epoch criterion was reached.

Hijri year

The Hijri year (Arabic: سَنة هِجْريّة‎) or era (التقويم الهجري at-taqwīm al-hijrī) 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 (now Medina). This event, known as the Hijra, is commemorated in Islam for its role in the founding of the first Muslim community (ummah).

In the West, this era is most commonly denoted as AH (Latin: Anno Hegirae , "in the year of the Hijra") in parallel with the Christian (AD), Common (CE) and Jewish eras (AM) and can similarly be placed before or after the date. In Muslim countries, it is also commonly abbreviated H ("Hijra") from its Arabic abbreviation hāʾ (هـ). Years prior to AH 1 are reckoned in English as BH ("Before the Hijra"), which should follow the date.Because the Islamic lunar calendar has only 354 or 355 days in its year, it slowly rotates relative to the Gregorian year. The year 2019 CE corresponds to the Islamic years AH 1440 – 1441. AH 1440 corresponds to 2018 – 2019 in the Common Era.

Holocene calendar

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 (AD/BC or CE/BCE) 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 12019 HE. The HE scheme was first proposed by Cesare Emiliani in 1993 (11993 HE).

List of Digambar Jain ascetics

This is a list of the ascetics belonging to the Digambara sect of Jainism. These ascetics are known for their contributions to Jain philosophy and Jainism in general. According to Digambar jain history there are about three less than ten million jain ascetics till this date that have achieved Moksha.

Mukhya Upanishads

Mukhya Upanishads, also known as Principal Upanishads, are the most ancient and widely studied Upanishads of Hinduism. Composed between 800 BCE to the start of common era, these texts are connected to the Vedic tradition. While some early colonial era Indology listed 10 Upanishads as Mukhya Upanishads, most scholars now consider the Principal Upanishads to be thirteen.

Īśā (IsUp), Yajurveda

Kena (KeUp), Samaveda

Kaṭha (KaUp), Yajurveda

Praṣna (PrUp), Atharvaveda

Muṇḍaka (MuUp), Atharvaveda

Māṇḍūkya (MaUp), Atharvaveda

Taittirīya (TaiUp), Yajurveda

Aitareya, (AiUp), Rigveda

Chāndogya (ChhUp), Samaveda

Bṛhadāraṇyaka (BṛUp), Yajurveda

Shvetashvatara Upanishad

Kaushitaki Upanishad

Maitri UpanishadThe first ten of the above Principal Upanishads were commented upon by the 8th century scholar, Adi Shankara. The adjective mukhya means "principal", "chief", or "primary". The Mukhya Upanishads are accepted as śruti by all Hindus, or the most important scriptures of Hinduism.The Principal Upanishads (1953) by Sarvepalli Radhakrishnan gives the text and English translation of a total of eighteen Upanishads, including the 13 listed by Hume (1921), plus Subāla, Jābāla, Paiṅgala, Kaivalya, Vajrasūcikā (Muktika nos. 30, 13, 59, 12 and 36).

Nāgarī script

The Nāgarī script is the ancestor of Devanagari, Nandinagari and other variants, and was first used to write Prakrit and Sanskrit. The term is sometimes used as a synonym for Devanagari script. It came in vogue during the first millennium CE.The Nāgarī script has roots in the ancient Brahmi script family. Some of the earliest epigraph evidence attesting to the developing Sanskrit Nāgarī script in ancient India is from the 1st to 4th century CE inscriptions discovered in Gujarat. The Nāgarī script was in regular use by 7th century CE, and had fully evolved into Devanagari and Nandinagari scripts by about the end of first millennium of the common era.

Saracen

Saracen was a term widely used among Christian writers in Europe during the Middle Ages to refer to Arabs and Muslims. The term's meaning evolved during its history. In the early centuries of the Common Era, Greek and Latin writings used this term to refer to the people who lived in desert areas in and near the Roman province of Arabia Petraea, and in Arabia Deserta. In Europe during the Early Middle Ages, the term came to be associated with tribes of Arabia. The oldest source mentioning the term Saracen dates back to the 7th century. It was found in Doctrina Jacobi, a commentary that discussed the event of the Arab conquests on Palestine.By the 12th century, "Saracen" had become synonymous with "Muslim" in Medieval Latin literature. Such expansion in the meaning of the term had begun centuries earlier among the Byzantine Greeks, as evidenced in documents from the 8th century. In the Western languages before the 16th century, "Saracen" was commonly used to refer to Muslim Arabs, and the words "Muslim" and "Islam" were generally not used (with a few isolated exceptions). The term became gradually obsolete following the Age of Discovery.

Thai calendar

In Thailand, two main calendar systems are used alongside each other: the Thai solar calendar, based on the Gregorian calendar, used for official and most day-to-day purposes, and the Thai lunar calendar (a version of the Buddhist calendar, technically a lunisolar calendar), used for traditional events and Buddhist religious practices.

The use of the solar calendar was introduced in 1889 by King Chulalongkorn (Rama V), replacing the lunar calendar in official contexts. Originally placing the beginning of year on 1 April, this was changed to 1 January in 1941, so the days and months now correspond exactly to the Gregorian calendar. Numbering of the years follow the Buddhist Era, introduced in 1913 to replace the Rattanakosin Era, which in turn replaced the Chula Sakarat in 1889. The reckoning of the Buddhist Era in Thailand is 543 years ahead of the Common Era (Anno Domini), so the year 2019 CE corresponds to B.E. 2562.

The lunar calendar contains twelve or thirteen months in a year, with 15 waxing moon and 14 or 15 waning moon days in a month, amounting to years of 354, 355 or 384 days. The years are usually noted by the animal of the Chinese zodiac, although there are several dates used to count the New Year.

As with the rest of the world, the seven-day week is used alongside both calendars. The solar calendar now governs most aspects of life in Thailand, and while official state documents invariably follow the Buddhist Era, the Common Era is also used by the private sector. The lunar calendar determines the dates of Buddhist holidays, traditional festivals and astrological practices, and the lunar date is still recorded on birth certificates and printed in most daily newspapers.

Timeline of Jainism

Jainism is an ancient Indian religion belonging to the śramaṇa tradition. It prescribes ahimsa (non-violence) towards all living beings to the greatest possible extent. The three main teachings of Jainism are ahimsa, anekantavada (non-absolutism), aparigraha (non-possessiveness). Followers of Jainism take five main vows: ahimsa, satya (not lying), asteya (non stealing), brahmacharya (chastity), and aparigraha. Monks follow them completely whereas śrāvakas (householders) observe them partially. Self-discipline and asceticism are thus major focuses of Jainism.

Vaiśeṣika Sūtra

Vaiśeṣika Sūtra, (Sanskrit: वैशेषिक सूत्र), also called Kanada sutra, is an ancient Sanskrit text at the foundation of the Vaisheshika school of Hindu philosophy. The sutra was authored by the Hindu sage Kanada, also known as Kashyapa. According to some scholars, he flourished before the advent of Buddhism because the Vaiśeṣika Sūtra makes no mention of Buddhism or Buddhist doctrines; however, the details of Kanada's life are uncertain, and the Vaiśeṣika Sūtra was likely compiled sometime between 6th and 2nd century BCE, and finalized in the currently existing version before the start of the common era.A number of scholars have commented on it since the beginning of common era; the earliest commentary known is the Padartha Dharma Sangraha of Prashastapada. Another important secondary work on Vaiśeṣika Sūtra is Maticandra's Dasha padartha sastra which exists both in Sanskrit and its Chinese translation in 648 CE by Yuanzhuang.The Vaiśeṣika Sūtra is written in aphoristic sutras style, and presents its theories on the creation and existence of the universe using naturalistic atomism, applying logic and realism, and is one of the earliest known systematic realist ontology in human history. The text discusses motions of different kind and laws that govern it, the meaning of dharma, a theory of epistemology, the basis of Atman (self, soul), and the nature of yoga and moksha. The explicit mention of motion as the cause of all phenomena in the world and several propositions about it make it one of the earliest texts on physics.
