Parameter 3: Date (month year, e.g. November 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.
