Template:Birth date and age/doc

This template will return a living person's date of birth and age. 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.

This template is intended for use in an article about a living person. For an article about a dead person, use Birth date with Death date and age.

Usage

 * Unnamed parameters for year, month, day


 * Named parameters for year, month, day

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=yes or mf=y.

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.

Error tracking
Some kinds of invalid input are tracked in Category:Pages using age template with invalid date.
