Editing Template:Birth date and age/doc (section)

=== hCard microformat ===
This template also returns the date, hidden by CSS, in the [[WP:ISO 8601|ISO 8601]] standard.<ref>{{cite web | date = April 7, 2013 | url = http://microformats.org/wiki/date-pattern | title = Date Design Pattern | website = Microformats Wiki}}</ref>
<ref>{{cite web | date = August 28, 2009 | url = http://microformats.org/wiki/hcalendar-issues-closed | title = hCalendar closed issues | website = Microformats Wiki}} Specifically rejects supporting the Julian calendar.</ref> For example:
: <code><nowiki>(<span class="bday">1993-02-24</span>)</nowiki></code>
Note: For the "foundation", "built" and similar set-up dates of companies, buildings etc., use {{tl|start date}} (this will work for year-only or month-year dates). Because the ISO 8601 standard requires the [[Gregorian calendar]], this template should not be used if the date is given in the [[Julian calendar]].
