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. This is a hidden category. It is not shown on its member pages, unless the corresponding user preference (Appearance → Show hidden categories) is set. Administrators: Please do not delete this category even if it is empty! This category may be empty occasionally or even most of the time.

Supported templates:

• {{Start date}} (parameter usage report)
• {{End date}} (parameter usage report)
• {{End date and age}} (parameter usage report)
