This template indicates that the article cites a source that previously got its information from Wikipedia. Wikipedia may not cite itself, and citing a source that comes from Wikipedia is a circular reference, and may not be used as a citation for the same reason.
{{Circular}}{{Circular|date=September 2024}}{{Circular|section}}
This template has one positional parameter and three named parameters, all optional:
.svg/1280px-Test_Template_Info-Icon_-_Version_(2).svg.png){kind=icon}
|1= — scope of the message; set |1=section to have the message say, "This section..." (default: "This article").|date= — month name and date, e.g.: |date=September 2024 (default: none, but supplied by bot if omitted). Supports § Categorization.|small= — banner placement; set |small=no to have a wide, centered banner (default: narrow, left-margin banner)|name= — for advanced usage only; see {{Ambox#name}}.The |date= parameter sorts the article into date-named subcategories such as Category:Articles lacking reliable references from September 2024 and out of the parent category (same name, without the date), allowing the oldest problems to be identified and dealt with first.
A bot will add this parameter if it is omitted. Be careful not to abbreviate the date, because then it will automatically add a redlinked category instead of the correct category. The simplest way to use this parameter manually is {{Circular| but it can be done more explicitly as {{subst:DATE}}}}{{Circular|date=September 2024}} (both result in the same output). Do not use {{Circular|date={{subst:DATE}}}} as {{DATE}} includes the leading date=.
