Category:CS1 maint: date and year

This is a tracking category. It is used to build and maintain lists of pages—primarily for the sake of the lists themselves and their use in article and category maintenance. It is not part of the encyclopedia's categorization scheme. More information: This category is hidden on its member pages—unless the corresponding user preference is set. These categories are used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience. These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).

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

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 messages are hidden from all readers.

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

(Note to new editors: those are pages that are specific to you, and control your view of pages, by adding to the CSS code. If you have not yet created such a page, then clicking one of the .css links above will yield a page whose first two lines of text are: Wikipedia does not have a user page with this exact name. Before creating this page, please see Wikipedia:Subpages. and Start the User:(your username)/common.css page. Click the second line to start creating the page, paste the text below, save the page, follow the instructions at the bottom of the new page on bypassing your browser's cache, and finally, in order to see the previously hidden maintenance messages, refresh the page you were editing earlier.)

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

To display hidden-by-default error messages:

.mw-parser-output span.cs1-hidden-error {display: inline;} /* display hidden Citation Style 1 error 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 normally-displayed 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.

Nota bene: these css rules are not obeyed by Navigation popups.
