Template:Use dmy dates
 | This template is used on approximately 1,560,000 pages, or roughly 4170% of all pages. To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them. |
Usage
To promote consistent date formatting, place this template with other maintenance tags near the top of articles that use the d mmmm yyyy date format (below hatnotes, but above infoboxes, as per the Manual of Style). Use the parameter |date= for the month and year that an editor or bot last checked the article for inconsistent date formatting and fixed any found.
Wikipedia articles that use d mmmm yyyy dates, either because of the first main contributor rule or close national ties (see MOSNUM), are systematically tagged with {{Use dmy dates}} over time. The template is invisible except in edit mode.
The template is useful to the editors to quickly know which date format is to be used when adding new dates into an article. It also facilitates article maintenance by enabling bots to recognise use of this format, and by adding the article to the hidden category Use dmy dates.
Use of this template is part of a continuing effort to monitor the date formats used in articles, to assist in maintaining consistent formatting within an article. It is not a temporary "cleanup" template. Therefore, do not remove the template without valid reason, such as a determination the article uses or should use a different date format.
After being tagged, and bearing in mind article evolution, periodic script or bot runs clean up formats, correcting any new introductions since its last visit, and updating the visit date on the {{Use dmy dates}} template.
The dmy and mdy templates have almost always been used to indicate date styles in the body of the articles; although it may also indicate the flavour of dates in reference sections or parts thereof. Therefore, this template notice ought to be read in conjunction with the blurb at Wikipedia:Date formattings. MOSNUM script documentation may also be relevant to those interested.
When a citation style does not expect differing date formats, it is permissible to normalize publication dates to the article body text date format, and access/archive dates to either, with date consistency being preferred (see MOS:DATEUNIFY).
Auto-formatting citation template dates
Citation Style 1 and 2 (collectively cs1|2) templates automatically render dates (|date=, |access-date=, |archive-date=, etc) in the style specified by this template. Because it is allowed by WP:MOSDATES, the cs1|2 templates can automatically format dates in a variety of styles. Editors may choose how cs1|2 templates render dates by the use of |cs1-dates=<keyword>.
{{#lst:Help:Citation Style 1|auto_date_format_table}}
An example is given at Help:Citation Style 1 § Auto-formatting citation template dates.
Nota bene: cs1|2 auto-date formatting does not apply when previewing an article section that does not contain a {{use xxx dates}} template. When editing with the visual editor, changes to this template do not take effect until the page is saved.
Syntax
{{Use dmy dates|date=November 2024}}
Notes:
- The template should be inserted in one of the first few lines of code of an article (to improve performance).
- Do not use redirects of this template, because otherwise its presence in an article may not be recognized by date formatting templates and bots. (There are a number of "legacy redirects" which are still supported at least by CS1/CS2 citation templates, but they should be changed to direct invocations of this template, also for performance reasons.)

Wrongly tagged?
If, for example, you determine that an article has a template that is inappropriate for its nationality, you should replace it with the appropriate template to avoid scripts or bots reapplying the "wrong" format in the course of maintenance.
