Template:Citation Style documentation/date


 * date: Date of referenced source. Can be full date (day, month, and year) or partial date (month and year, season and year, or year). Use same format as other publication dates in the citations. Do not wikilink. Displays after the authors and is enclosed in parentheses. If there is no author, then displays after the website and publisher.
 * Shortened footnotes target full citations using the year specified in this parameter. A lowercase letter may be suffixed to the year to disambiguate links to multiple works by the same author in the same year,$[more]$ unless the date is formatted as YYYY-MM-DD. In the latter case, year or ref is required to disambiguate the link targets.
 * For approximate year, precede with " ", like this: c. 1900.


 * For no date, or "undated", use n.d.
 * The date of a Web page, PDF, etc. with no visible date can sometimes be established by searching the page source or document code for a  or   date; a comment for editors such as   can be added.


 * year: Year of publication. The more flexible date parameter also handles a year by itself. Do not use in combination with the  parameter, unless both of the following conditions are met:
 * Shortened footnotes target multiple citations with same last name and year of publication. (This situation necessitates a  disambiguator, usually a lowercase letter suffixed to the year.)
 * The  format is YYYY-MM-DD. (This format prevents the addition of a disambiguating letter to the year.)
 * df: date format; sets rendered dates to the specified format; does not support date ranges or seasonal dates; overrides the automatic date formatting described above. Accepts one value which may be one of these:
 * – set publication dates to day month year format; access- and archive-dates are not modified;
 * – as above for month day, year format
 * – as above for year initial numeric format YYYY-MM-DD
 * – set publication, access-, and archive-dates to day month year format;
 * – as above for month day, year format
 * – as above for year initial numeric format YYYY-MM-DD
