Category:CS1 maint: date and year

This is a tracking category for CS1 citations that use |date= and |year=. With the implementation of date checking in Module:Citation/CS1, separate |date= and |year= parameters for CITEREF disambiguation became unnecessary except in the case where |date= holds a year-initial numeric date (YYYY-MM-DD) which style does not support CITEREF disambiguation. Citations that use both parameters should be inspected and where possible the redundant |year= parameter removed and if appropriate, the |date= parameter modified to include the CITEREF disambiguator. Pages in this category should only be added by Module:Citation/CS1.

Editors who use AWB may wish to use this AWB script as an aid to clearing this category.

By default, Citation Style 1 and Citation Style 2 error messages are visible to all readers and maintenance category messages are hidden from all readers.

To display maintenance messages, include the following text in your common CSS page or your specific skin's CSS page (common.css and skin.css respectively):

.mw-parser-output span.cs1-maint {display: inline;} /* display Citation Style 1 maintenance messages */

Even with this css installed, older pages in Wikipedia's cache may not have been updated to show these error messages even though the page is listed in one of the tracking categories. A null edit will resolve that issue.

To hide error messages:

.mw-parser-output span.cs1-visible-error {display: none;} /* hide Citation Style 1 error messages */

You can personalize the display of these messages (such as changing the color), but you will need to ask someone who knows CSS or at the technical village pump if you do not understand how.
