{{tl|Birth-date and age}} displays a person’s birth date and age. Besides calculating the age of the person, the benefit of using this template is to allow for the inclusion of hidden [[microformat]] dates, which may be indexed or searched by software tools.

Note: The template may not calculate the age correctly if a full date (month, day, year) is not provided. For example, a person who was born in 1941 could be either {{#expr:{{CURRENTYEAR}}-1941-1}} or {{#expr:{{CURRENTYEAR}}-1941}}, depending on whether they have reached their birthday in the current year:
: <code><nowiki>{{Birth-date and age|</nowiki>1941}}</code> → {{Birth-date and age|1941}}
: <code><nowiki>{{Birth-date and age|</nowiki>{{CURRENTMONTHNAME}} 1941}}</code> → {{Birth-date and age|{{CURRENTMONTHNAME}} 1941}}
When only the year is known, consider using {{tl|Birth year and age}} instead:
: <code><nowiki>{{Birth year and age|</nowiki>1941}}</code> → {{Birth year and age|1941}}
: <code><nowiki>{{Birth year and age|</nowiki>1941|{{#expr:{{CURRENTMONTH}}}}}}</code> → {{Birth year and age|1941|{{#expr:{{CURRENTMONTH}}}}}}

== Usage ==
; Format:
: <code><nowiki>{{Birth-date and age| birth date }}</nowiki></code>
: <code><nowiki>{{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. }}</nowiki></code>
