{{Birth date}} will return a person's date of birth. Using this template rather than simply inserting the date into articles allows for the inclusion of hidden metadata about the date. This metadata can be used by web browsers and other software tools to extract the details, and display them using some other website or mapping tool, index, or search them.

For an article about a living person, consider using {{Birth date and age}} instead.

Usage

Unnamed parameters for year, month, day
{{Birth date|year of birth|month of birth|day of birth|additional parameters}}
Named parameters for year, month, day
{{Birth date|year=year of birth|month=month of birth|day=day of birth|additional parameters}}

Additional parameters

The |df= (day first) and |mf= (month first) parameters indicate the intended date format to display. The appropriate parameter should be set to "y" or "yes", e.g. |df or |df.

The default output of this template is to display the month before the day. This default may not be appropriate for articles about people from parts of the world where the day precedes the month in a date. In such articles the parameter, |df=, should be set to display the day before the month.

The parameter |mf=, while not actually used by the template, will indicate that month first format is intended. Using these parameters can assist bots or other automated processing to detect which date format is intended; leaving the format as default may lead an editor or bot to change the format to an unintended value.

Do not specify both |df= and |mf= parameters in the same use of the template, as these formats are mutually exclusive.

hCard microformat

This template also returns the date, hidden by CSS, in the ISO 8601 standard. For example:

(<span class="bday">1993-02-24</span>)

Because the ISO 8601 standard requires the Gregorian calendar, this template should not be used if the date is given in the Julian calendar.

For further information, visit the microformats project.

Notes

  • Do not use with non-Gregorian dates because the resulting hCard hidden date will be false.
  • The template will appear broken when the parameters are left blank.

Examples

Unnamed parameters for year, month, day:

{{Birth date|1993|2|24}} → "February 24, 1993"
{{Birth date|1993|2|24|df=yes}} → "24 February, 1993"
{{Birth date|1993|2|24|mf=yes}} → "February 24, 1993"

Named parameters for year, month, day:

{{Birth date|year=1993|month=2|day=24}} → "February 24, 1993
{{Birth date|year=1993|month=2|day=24|df=yes}} → "24 February, 1993
{{Birth date|year=1993|month=2|day=24|mf=yes}} → "February 24, 1993
