This template converts dates to [[ISO dates]] (YYYY-MM-DD or YYYY-MM or YYYY as appropriate), see below for restrictions on input formats accepted.
== Usage ==
The template mat be used without any parameters, in which case it displays the current date:
* <tt><nowiki>{{ISO end date}}</nowiki></tt> returns {{ISO end date}}
The template accepts one unnamed parameter containing a date in one of the following formats:
* <tt><nowiki>{{ISO end date|15 January 2001}}</nowiki></tt> returns {{ISO end date|15 January 2001}}
* <tt><nowiki>{{ISO end date|15 Jan 2001}}</nowiki></tt> returns {{ISO end date|15 Jan 2001}}
* <tt><nowiki>{{ISO end date|15-01-2001}}</nowiki></tt> returns {{ISO end date|15-01-2001}}
* <tt><nowiki>{{ISO end date|January 15, 2001}}</nowiki></tt> returns {{ISO end date|January 15, 2001}}
* <tt><nowiki>{{ISO end date|Jan 15, 2001}}</nowiki></tt> returns {{ISO end date|Jan 15, 2001}}
* <tt><nowiki>{{ISO end date|Jan. 15, 2001}}</nowiki></tt> returns {{ISO end date|Jan. 15, 2001}}
* <tt><nowiki>{{ISO end date|01/15/2001}}</nowiki></tt> returns {{ISO end date|01/15/2001}}
* <tt><nowiki>{{ISO end date|January 2001}}</nowiki></tt> returns {{ISO end date|January 2001}}
* <tt><nowiki>{{ISO end date|Jan 2001}}</nowiki></tt> returns {{ISO end date|Jan 2001}}
* <tt><nowiki>{{ISO end date|2001}}</nowiki></tt> returns {{ISO end date|2001}}
Formats for which it can not work because [[Help:Time function|#time]] returns an error or an incorrect ISO format:
* <tt><nowiki>{{ISO end date|01-15-2001}}</nowiki></tt> returns {{ISO end date|01-15-2001}} ''(hyphens indicate DD-MM-YYYY and 15 is an invalid month number)''
* <tt><nowiki>{{ISO end date|15/01/2001}}</nowiki></tt> returns {{ISO end date|15/01/2001}} ''(slashes indicate MM/DD/YYYY and 15 is an invalid month number)''
* <tt><nowiki>{{ISO end date|1/2001}}</nowiki></tt> returns {{ISO end date|1/2001}}
* <tt><nowiki>{{ISO end date|2001 January 15}}</nowiki></tt> returns {{ISO end date|2001 January 15}}
* <tt><nowiki>{{ISO end date|2001 January}}</nowiki></tt> returns {{ISO end date|2001 January}} ''(expected: {{ISO end date|January 2001}})''
== Use in microformats ==
This template also wraps the date in the <code>dtend</code> classes needed by the [[hCalendar]] [[microformat]] - usually, but not always, within infobox or similar templates, or tables.
'''Note: due to the requirement exclusive "dtend" in [[hCalendar]], and the accessibility problems that presents when a date is rendered (as seen without CSS) as <tt>28 March 1999 (1999-03-29)</tt> or even <tt>28 February 1999 (1999-03-01)</tt> or <tt>31 December 1999 (2000-01-01)</tt>, this template should '''not''' be used for whole-day dates.'''
