Besides calculating the age of the person, the benefit of using this template, is to allow for the inclusion of hidden metadata to be used, indexed or searched by software tools.

Typical Usage

Format
{{Birth-date and age| birth date}}
{{Birth-date and age| birth date | wikitext to display in place of 'birth date'. Like the right hand parameter in a wikilink, this could be alternate text, links, templates etc. }}
