Editing Monday (section)

==Arrangement in the week==
Historically, the Greco-Roman week began with Sunday (''dies solis''), and Monday (''dies lunae'') was the second day of the week.<ref name=":0" /> It is still the custom to refer to Monday as ''feria secunda'' in the  [[Liturgical year|liturgical calendar]] of the [[Catholic Church]]. [[Religious Society of Friends|Quakers]] also traditionally referred to Monday as "Second Day".<ref>{{cite web |url=http://iymc.org/calendarnames.html |title=Guide to Quaker Calendar Names |author=<!--Not stated--> |publisher=Iowa Yearly Meeting (Conservative) Religious Society of Friends (Quakers) |access-date=30 March 2017 |quote=In the 20th Century, many Friends began accepting the use of the common date names, feeling that any pagan meaning has been forgotten. The numerical names continue to be used, however, in many documents and more formal situations."}}</ref>

The [[Portuguese language|Portuguese]] and the [[Greek language|Greek]] (Eastern Orthodox Church) also retain the ecclesiastical tradition (Portuguese ''segunda-feira'', Greek ''Δευτέρα'' "''deutéra''" "second"). [[Vietnamese language|Vietnamese]], whose [[Vietnamese alphabet#Creation of chữ Quốc ngữ|Latin-based alphabet]] was originally [[romanization|romanized]] by Portuguese [[Jesuits|Jesuit]] [[missionary|missionaries]], adopted this convention and thus also refers to Monday as Second Day (''thứ Hai''). Likewise, the [[Modern Hebrew]] name for Monday is ''yom-sheni'' (יום שני).

While in North America, Sunday is the first day of the week, the Geneva-based [[International Organization for Standardization]] places Monday as the first day of the week in its [[ISO 8601]] standard. Monday is ''xīngqīyī (星期一)'' in [[Chinese language|Chinese]], meaning "day one of the week".
