Editing Comma (section)

===In dates===

====Month day, year====
When a date is written as a month followed by a day followed by a year, a comma separates the day from the year: December 19, 1941. This style is common in American English. The comma is used to avoid confusing consecutive numbers: December 19&nbsp;1941.
Most style manuals, including ''[[The Chicago Manual of Style]]''<ref>Chicago Manual of Style:
"It's conventional to put a comma after the year. The commas are like parentheses here, so it doesn't make sense to have only one."</ref>
and the ''[[AP Stylebook]]'',<ref>{{cite web |url= http://www.apstylebook.com/ask_editor.php |archive-url= https://web.archive.org/web/20081204072022/https://www.apstylebook.com/ask_editor.php |archive-date=4 December 2008 |title=Ask the Editor |access-date=7 June 2019 |work=AP Stylebook |date=3 December 2008 |quote=When a phrase refers to a month, day and year, set off the year with commas... ''Feb. 14, 1987, was the target date''.}}</ref>
also recommend that the year be treated as a parenthetical, requiring a second comma after it: ''"Feb. 14, 1987, was the target date."''

If just the month and year are given, no commas are used:<ref>{{cite web |url= https://terriblywrite.wordpress.com/terribly-right-writing-for-the-web/top-5-comma-errors/ |title=Top 5 Comma Errors |date=30 June 2008 |access-date=24 July 2020 |archive-date=28 July 2020 |archive-url= https://web.archive.org/web/20200728174136/https://terriblywrite.wordpress.com/terribly-right-writing-for-the-web/top-5-comma-errors/ |url-status=live}}</ref> "Her daughter may return in June 2009 for the reunion."

====Day month year====
When the day precedes the month, the month name separates the numeric day and year, so commas are not necessary to separate them: "The [[Raid on Alexandria (1941)|Raid on Alexandria]] was carried out on 19&nbsp;December&nbsp;1941."
