Administrators: Please do not delete this category as empty!

This category may be empty occasionally or even most of the time.

Articles in category contain statements that may become dated originating from the future. This generally indicates an erroneous parameter was passed to the template.

• Wikipedia:As of for details of dealing with statements that date quickly.
• Wikipedia:Avoid statements that will date quickly for guidelines on using precise language when dealing with information that may date quickly.
• Category:Wikipedia articles in need of updating and the accompanying {{Update after}} template.
