WarningThis template is used on approximately 4,300 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.
This template uses Lua:
  • Module:Check for unknown parameters

The {{End date and age}} template displays the date that an event or entity ended. It also includes a duplicate, machine-readable date in the ISO 8601 format (which is hidden by CSS), for use inside other templates which emit microformats. The hidden date degrades gracefully when CSS is not available.

Usage

Common usage
{{End date and age|yyyy|mm|dd}} to display formatted as:
March 25, 2010; 15 years ago (2010-03-25)
{{End date and age|yyyy|mm|dd|df=yes}} to display formatted as:
25 March 2010; 15 years ago (2010-03-25)
Full syntax
{{End date and age|yyyy|mm|dd|df=yes|p=yes|br=yes}} to display formatted as:
25 March 2010
(15 years ago)
 (2010-03-25)

Parameters

Parameter Status Description
1 required A four-digit number indicating the year.
2 optional A number between 1 and 12 indicating the month (leading zeros in the number are ignored). The month may also be specified as a name or abbreviation (e.g. "August" or "Aug").
3 optional A number between 1 and 31 indicating the day of the month (leading zeros in the number are ignored).
df= optional If the parameter df equals yes, y, or 1, the date will be displayed in DMY format: 4 March 2010. When this parameter is not included or set to some other value, the date will be displayed in MDY format: March 4, 2010.
p=
paren=
optional If the parameter p or paren equals yes, y, or 1, the age will be displayed within parentheses. When this parameter is not included or set to some other value, the date and age are separated by a semicolon and a breaking space.
br= optional If the parameter br equals yes, y, or 1, a line break will be inserted between the date and the age. When this parameter is not included or set to some other value, a breaking space will be inserted between the date and the age. This does not change the separating characters between the date and age which are either a semicolon (default setting) or parentheses (if p=yes).

"df" (day first) and "mf" (month first)

The default output of this template is to display the month before the day (MDY). This default may not be appropriate for articles about events or entities in parts of the world where dates are commonly given with the day preceding the month (DMY). To display the day first, assign the df parameter a value of yes, y, or 1 (e.g. df=yes).

If the default format is preferred, the parameter df may be used with value of no, n, or 0 (e.g. df=no). These values can assist bots or other automated processing to detect the intended date format; omitting the df parameter may lead an editor or bot to change the format to an unintended value.

The preference to display the month first may also be indicated via the parameter mf (e.g. mf=yes). While not actually used by the template, this is another method of indicating that the default format is intended. Do not specify both "df" and "mf" parameters in the same use of the template.

Use in microformats

The template returns the date as hCalendar's (class="dtend"). For example:

(<span class="dtend">1993-02-24T08:30</span>)

(disable CSS or view source to see the hidden ISO-formatted output).

See the microformats project for further details.

Example

  • {{End date and age|2015|12|31}} → December 31, 2015; 9 years ago (2015-12-31)
    December&nbsp;31, 2015<span class="noprint">&#059;&#032;9 years ago</span><span style="display:none">&#160;(<span class="dtend">2015-12-31</span>)</span>
