Usage

• This template adds a category or dated category to a page.
• It will add the page to an optional additional category.
• If the dated category is invalid it will add the page to Category:Articles with invalid date parameter in template

Syntax

• Parameter 1: Default category name (without Category) – the category if there is no date, but also the stem of the category name when there is a date..
• Parameter 2: Preposition (from, since, in, as of).
• Parameter 3: Date (month year, e.g. October 2025. Usually the "date" parameter of the calling template {{{date|}}}.
• Parameter 4: Category all the articles go in, dated or not (if there is one).
• Parameter 5: Alternative default category, used when parameter 1 is right for forming the dated category, but the undated items need to go somewhere else.

Technical

The parameter onlyarticles ({{Dated maintenance category}} only) is used for template design, restricting the function of this template to article namespace (as in {{DMCA}} ).

• {{DMCA|Articles to be split|from|{{{date|}}}|All articles to be split}} will categorise all articles in Category:Articles to be split from September 2025, if the date is set September 2025 e.g. If such a category does not exist, or the date was set incorrectly, this template will also add the article to Category:Articles with invalid date parameter in template. In either case the article will be added to Category:All articles to be split.

An incorrect date is any date which is not of the form October 2025, e.g. October 24, 2025, or june instead of June, or other spelling mistakes.
