This is a maintenance category, used for maintenance of the Wikipedia project. It is not part of the encyclopedia and contains non-article pages, or groups articles by status rather than subject. Do not include this category in content categories. This is a hidden category. It is not shown on its member pages, unless the corresponding user preference (Appearance → Show hidden categories) is set.

Wikipedia articles (tagged in this month) that use "dd mm yyyy" date formats, whether by application of the first main contributor rule or by virtue of close national ties to the subject, belong in Category:Use dmy dates. Use {{ Dmy}} or {{ Use dmy dates}} to add an article to this category. See Wikipedia:MOSNUM.

This system of tagging/categorisation is used as a status monitor of all articles that use dd mm yyyy date formats.
