Template:Birth date and age/doc

Usage
These templates (Birth date and Birth date and age) return a person's date of birth and optionally his/her age. The latter also have the shortcut: Bda.

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.

Syntax:



or


 * year of birth
 * year of birth

Examples:


 * February 4, 1993 returns "February 4, 1993"
 * February 4, 1993 returns "February 4, 1993"
 * February 24, 1993 returns "February 24, 1993"


 * February 4, 1993 returns February 4, 1993
 * February 4, 1993 returns February 4, 1993
 * February 24, 1993 returns February 24, 1993

An optional parameter, df, can be set (to "y" or "yes" for example) to display the day before the month. This is primarily used in articles about people from parts of the world where the day precedes the month in a date. Conversely the (unimplemented) parameter mf can be set for month first, currently the default behaviour.

Examples:


 * February 24, 1993 returns "February 24, 1993"


 * February 24, 1993 returns "February 24, 1993"

The templates also return the date, hidden by CSS, in the ISO 8601 format needed by hCard microformats. for example:


 * ( 1993-02-24 )

See the microformats project for details.

When only the year of a person's birth and/or death are known, or if it is desired not to state a person's full dates of birth and death for privacy reasons, use the templates Birth year and age and Death year and age instead.

Note: The template will appear broken when the parameters are left blank (as seen above).

Note: Do not use this template inside of the Persondata template as it can interfere with data extraction.
