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

Month First (mf) and Day First (df) Options
The default output of this template is to display the month before the day. The majority of readers will see the date displayed this way because they aren't logged in and therefore don't have accounts with a date preference set. This default may not be appropriate articles about people from parts of the world where the day precedes the month in a date. In such articles the optional parameter, "df", can be set (to "y" or "yes" for example) to display the day before the month. Conversely the parameter "mf" can be set for month first, currently the default behaviour.
