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.Template:R Required when year is used to disambiguate Template:Tlx links to multiple-work citations by the same author in the same year.Template:Sup Do not wikilink. Displays after the authors and is enclosed in parentheses. If there is no author, then displays after the publisher. Template:Hatnote inline

For approximate year, precede with "c. ", like this: Template:Para.

For no date, or "undated", use Template:Para

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 created or updated date; a comment for editors such as date=2021-12-25<!--date from page source-->|orig-date=Original date 2011-01-01 can be added.

Automatic date formatting: Citation Style 1 and 2 templates, including this template, automatically render dates in all date parameters (such as Template:Para, Template:Para, Template:Para, Template:Para, etc.) except for Template:Para in the style specified by the article's Template:Tlx or Template:Tlx template. See those templates' documentation for details.

• year: Year of source being referenced. The usage of this parameter is discouraged; use the more flexible Template:Para parameter instead unless Template:Em of the following conditions are met:
  1. The Template:Para format is YYYY-MM-DD.
  2. The citation requires a CITEREF disambiguator.
• orig-date: Original publication date or year; displays in square brackets after the date (or year). For clarity, please supply specifics. For example: Template:Para or Template:Para. As Template:Para does not support automatic date formatting, use the same date format as defined by Template:Para (or, if it exists in the article, by Template:Para of a Template:Tlx or Template:Tlx template), or as used in the Template:Para parameter. Alias: orig-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:

  dmy – set publication dates to day month year format; access- and archive-dates are not modified;

  mdy – as above for month day, year format

  ymd – as above for year initial numeric format YYYY-MM-DD

  dmy-all – set publication, access-, and archive-dates to day month year format;

  mdy-all – as above for month day, year format

  ymd-all – as above for year initial numeric format YYYY-MM-DD
