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. Required when year is used to disambiguate links to multiple-work citations by the same author in the same year.$[more]$ Do not wikilink. Displays after the authors and is enclosed in parentheses. If there is no author, then displays after publisher..
 * For approximate year, precede with " ", like this: c. 1900.


 * For no date, or "undated", use n.d.


 * year: Year of source being referenced. The usage of this parameter is discouraged; use the more flexible date parameter instead unless of the following conditions are met:
 * The date format is YYYY-MM-DD.
 * The citation requires a  disambiguator.
 * orig-date: Original publication date or year; displays in square brackets after the date (or year). For clarity, please supply specifics. For example: First published 1859 or Composed 1904. As orig-date does not support automatic date formatting, use the same date format as defined by df (or, if it exists in the article, by cs1-dates of a or  template), or as used in the date parameter. Alias: orig-year, origyear
 * 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
