Template:ISO date/doc

This template converts dates to YYYY-MM-DD or YYYY-MM or YYYY as appropriate - see below for restrictions on input formats accepted.

Usage

This template only converts dates formated in one of the formats below to an ISO date

The template accepts one parameter - which must be unnamed. For example:

• {{ISO date|15 January 2001}} returns 2001-01-15
• {{ISO date|March 2003}} returns 2003-03

The date parameter must be in one of the following formats:

• 15 January 2001
• 15 Jan 2001
• January 15, 2001
• Jan 15, 2001
• 15-01-2001
• January 2001
• Jan 2001
• 2001

Formats for which it can not work because #time returns an error:

• 01-15-2001
• 1/2001

Use in microformats

This template also returns the date, hidden by CSS, in the ISO 8601 format needed by one or more of the following microformats:

• hAtom (class="updated")
• hAudio (class="published")
• hCalendar (class="dtstart")
• hCard (class="bday")

usually, but not always, within infobox or similar templates, or tables.

Its use in hCard is for organisations, 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

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.
