Editing Epoch (section)

=== Modern eras ===
* The [[Bahá'í calendar]] is dated from the [[March equinox|vernal equinox]] of the year the [[Báb]] proclaimed his religion (AD 1844). Years are grouped in ''Váḥids'' of 19 years, and ''Kull-i-Shay'' of 361 (19×19) years.<ref>{{cite book |first=E. G. |last=Richards |chapter=Calendars |editor-first1=S.

* In [[Thailand]] in 1888 King [[Chulalongkorn]] decreed a National Thai Era dating from the founding of [[Bangkok]] on April 6, 1782. In 1912, New Year's Day was shifted to April 1. In 1941, [[Prime Minister of Thailand|Prime Minister]] [[Plaek Pibulsonggram|Phibunsongkhram]] decided to count the years since 543 BC. This is the [[Thai solar calendar]] using the Thai Buddhist Era. Except for this era, it is the Gregorian calendar.
* In the [[French Republican Calendar]], a calendar used by the French government for about twelve years from late 1793, the epoch was the beginning of the "Republican Era", September 22, 1792 (the day the [[French First Republic]] was proclaimed, one day after the Convention abolished the ''[[Ancien Regime]]'').
* The [[Indian national calendar]], introduced in 1957, follows the [[Saka era]] (AD 78).
* The [[Minguo calendar]] used by officials of [[Taiwan]] and [[Republic of China (1912–49)|its predecessor]] dates from January 1, 1912, the first year after the [[Xinhai Revolution]], which overthrew the [[Qing dynasty|Qing Empire]].
* [[North Korea]] uses a system that starts in 1912 (= [[Juche]] 1), the year of the birth of its founder [[Kim Il-Sung]].
* The [[Era Fascista|Fascist Era]] dates to [[Mussolini]]'s [[March on Rome]] in 1922, and was in use only in countries under hegemony of the Fascist regime of Benito Mussolini. It has been defunct since the fall of the [[Italian Social Republic]] in 1945. 
* In the scientific [[Before Present]] system of numbering years for purposes of [[radiocarbon dating]], the reference date is January 1, 1950 (though the specific date January 1 is quite unnecessary, as radiocarbon dating has limited precision).<ref>{{cite web |url=http://www.c14dating.com/agecalc.html |website=c14dating.com |title=Radiocarbon dating – Age calculation |last=Higham |first=Thomas |author-link1=Thomas Higham (archaeologist) |publisher=Thomas Higham (archaeologist) |access-date=December 31, 2009 |archive-date=June 10, 2007 |archive-url=https://web.archive.org/web/20070610195000/http://www.c14dating.com/agecalc.html |url-status=live }}</ref><ref>{{cite journal |last=Stuiver |first=Minze |author2=Polach HA |year=1977 |title=Discussion; reporting of C-14 data. |journal=Radiocarbon |publisher=University of Arizona |volume=19 |issue=3 |pages=355–363 |doi=10.1017/S0033822200003672 |bibcode=1977Radcb..19..355S |s2cid=56572650 |url=https://journals.uair.arizona.edu/index.php/radiocarbon/article/view/493/498 |access-date=October 5, 2018 |archive-date=August 17, 2020 |archive-url=https://web.archive.org/web/20200817043941/https://journals.uair.arizona.edu/index.php/radiocarbon/article/view/493/498 |url-status=live |doi-access=free }}</ref>
* Different branches of [[Freemasonry]] have selected different years to date their documents according to a Masonic era, such as the ''[[Anno Lucis]]'' (A.L.).
* The [[Holocene calendar]] uses 10,000 BC as the epoch, the beginning of the [[Holocene epoch]] on the [[geological time scale]].
