Cithakan:UF-date-part
This template also returns the date, hidden by CSS, in the ISO 8601 format needed by one or more of the following microformats:
usually, but not always, within infobox or similar templates, or tables.
Its use in hCard is for organizations, venues and similar; use {{Birth date}} or {{Birth date and age}} for people.
Similarly, {{End date}} returns the date as hCalendar's (class="dtend").
See the microformats project for further details.
Limitation
[besut sumber]This template has no provision to deal with a date in a non-Gregorian calendar. Also, ISO 8601 requires mutual agreement among those exchanging information before using years outside the range 1583–9999 CE. Therefore, use of this template for non-Gregorian dates or dates outside that range constitutes a false claim of conformance to the ISO 8601 standard.
Any editor encountering such usage should change the date to plain text with no template; or if not confident in doing so, raise the matter on this template's talk page.
