Category:Articles with invalid date parameter in template

File:Twemoji 1f527.svg

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).

Administrators: Please do not delete this category as empty!

This category may be empty occasionally or even most of the time.

This category contains articles that have an incorrect value in the date parameter of a maintenance template.

A correctly formatted date parameter consists of the fully spelled out and capitalized name of the month, a single space, and the four digit year. For example: date=October 2026. So no days and no short spelling for the names of months.

If the date is correctly formatted the article may still appear here. This can happen for three reasons, two common: The appropriate dated category;

does not exist - solve this by (re)creating the category (or changing the date in the parameter if it is clearly wrong).
did not exist at the last save - solve this by re-saving the article, either with a null edit, or any improvement you can make.
Rarely, if an article is in Category:Pages with too many expensive parser function calls, it can be listed here as well even if all of the date parameters are correct because #ifexist will always return false, so the tag will believe the dated category does not exist. Solution, is to fix the page (or the templates it calls) so that it does not have too many expensive parser function calls, alternatively resolve the problem needing the tag.
