== 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 <code>Category</code>) - 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. {{#time:F Y}}. Usually the "date" parameter of the calling template <code><nowiki>{{{date|}}}</nowiki></code>.
* 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'' ({{Tl|Dated maintenance category}} only) is used for template design, restricting the function of this template to article namespace (as in {{tl|DMCA}} ).

== Examples ==
* <code><nowiki>{{DMCFACT|Wikipedia articles that are too technical|from|{{{date|}}}}}</nowiki></code> will categorise all ''files'', ''articles'', ''categories'' and ''templates'' in [[:Category:Wikipedia articles that are too technical from {{#time:F Y|-1 month}}]], if the date is set {{#time:F Y|-1 month}} 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]]. 

* <code><nowiki>{{DMCAT|Wikipedia articles that are too technical|from|{{{date|}}}}}</nowiki></code> will categorise all ''articles'' and  ''article talk pages'' in [[:Category:Wikipedia articles that are too technical from {{#time:F Y|-1 month}}]], if the date is set {{#time:F Y|-1 month}} 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]]. 

* <code><nowiki>{{DMCA|Articles to be split|from|{{{date|}}}|All articles to be split}}</nowiki></code> will categorise all ''articles'' in [[:Category:Articles to be split from {{#time:F Y|-1 month}}]], if the date is set {{#time:F Y|-1 month}} 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]].

* <code><nowiki>{{DMCA|Dutch mathematicians}}</nowiki></code> is the straight category [[:Category:Dutch mathematicians]].

* <code><nowiki>{{TDMCA|type="Tolkien"|Articles to be split|from|{{{date|}}}|All articles to be split}}</nowiki></code> will categorise as in the above example but also in [[:Category:Tolkien articles to be split]] if it exists. If it doesn't the page will be added to the hidden [[:Category:Articles with tags with unsupported types]].

== Note ==
An incorrect date is any date which is not of the form {{#time:F Y}}, e.g. <code>{{#time:F d, Y}}</code>, or <code>june</code> instead of <code>June</code>, or other spelling mistakes.

==Etymology==
DMCA stands for "dated maintenance category - articles". Similar templates exist for certain other namespaces or combinations.  DMCA is a metatemplate with highly circumscribed use, and not intended to be "editor facing".
