Category:Articles using year nav template with extra parameters

This is a maintenance 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.

Administrators: Please do not delete this category as empty! This category may be empty occasionally or even most of the time.

This category is not shown on its member pages unless the appropriate user preference (appearance → show hidden categories) is set.

This category tracks uses of {{Year nav topic}} and similar templates that use more parameters than the template supports. {{Year nav topic5}}, for example, supports four topics; if a fifth topic is included in the template, an error message will be displayed, and the article will be placed in this category.
