Template:Dated maintenance category

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

Syntax


 * Parameter 1: Default category name
 * Parameter 2: Preposition (from, since, as at, as of)
 * Parameter 3: Date (Month Year, e.g. {{{CURRENTMONTHNAME}} 2024) usually the "date" parameter of the calling template
 * Parameter 4: All inclusive category name - e.g. All articles containing weasel words
 * Parameter 5: Alternative default category (overrides 1 which is then only used to construct the dated category if it exists)

Note
Even if the constructed dated category doesn't exist it is still used. This enables more rapid fault finding.
