Category:Use mdy dates from December 2019

Update this page

This is an administrative 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 (except for eponymous maintenance categories).

This is a tracking category. It builds and maintains a list of pages primarily for the sake of the list itself. They are not part of the encyclopedia's categorization scheme.

• This category is hidden on its member pages—unless the corresponding user preference (Appearance → Show hidden categories) is set.
• These categories can be used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience.
• These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).

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

This system of tagging or categorisation is used as a status monitor of all articles that use mm dd yyyy date formats, and not as a clean up.
