Usage

Place this template near the top of articles that use the mmm dd, yyyy date format; see Wikipedia:Manual of Style/Lead section for more information about the order of elements near the beginning of the article.

The purpose of this template is to allow bots to recognize that the 'mmm dd, yyyy' (aka 'American') date format has been applied to an article so tagged. It is visible only in edit mode. The template also categorizes the article in Category:Use mdy dates.

Wikipedia articles that use mmm dd yyyy date formats, whether by application of the first main contributor rule or by virtue of close national ties, are being systematically tagged with {{Use mdy dates}} to add an article to Category:Use mdy dates. See Wikipedia:Manual of Style/Dates and numbers.

This system of tagging/categorization is used as a status monitor of all articles that use mmm dd yyyy date formats, and not as a cleanup per se.

After being tagged, and bearing in mind article evolution, a WP:bot can eventually be programmed to clean up formats periodically, correcting any new introductions since its last visit, and updating the visit date on the {{Use mdy dates}} template.

Due to there being some objection to totally unifying date formats within an article, 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 flavor 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.

Wrongly tagged?

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