Editing Colon (punctuation) (section)

===Syntactical-descriptive===
In this sense the colon introduces a description; in particular, it makes explicit the elements of a set.
:''I have three sisters: Daphne, Rose, and Suzanne.''

Syntactical-descriptive colons may separate the numbers indicating [[hour]]s, [[minute]]s, and [[second]]s in abbreviated measures of time.<ref name="ISO8601">{{cite ISO standard |csnumber=40874 |title=Data elements and interchange formats – Information interchange – Representation of dates and times}}</ref>
:''The concert begins at 21:45.''
:''The rocket launched at 09:15:05.''

[[British English]] and [[Australian English]], however, more frequently use a [[decimal mark|point]] for this purpose:
:''The programme will begin at 8.00 pm.''
:''You will need to arrive by 14.30.''<ref name="trask">{{cite web |last1=Trask |first1=Larry |author1-link=Larry Trask |year=1997 |url=http://www.sussex.ac.uk/informatics/punctuation/colonandsemi/colon |title=The Colon |work=Guide to Punctuation |access-date=26 July 2019 |archive-date=16 January 2018 |archive-url=https://web.archive.org/web/20180116232539/http://www.sussex.ac.uk/informatics/punctuation/colonandsemi/colon |url-status=live}}</ref><ref>{{Cite book |last1=Peters |first1=Pam |editor1-last=Grayston |editor1-first=Graham |date=1995 |title=The Cambridge Australian English style guide |publisher=Cambridge University Press |isbn=978-0-521-43401-0 |location=Cambridge |page=146}}</ref>

A colon is also used in the descriptive location of a book verse if the book is divided into verses, such as in the [[Bible]] or the [[Quran]]:
:"Isaiah 42:8"
:"Deuteronomy 32:39"
:"Quran 10:5"
