Template:ISO date
2001-01-15
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 may be used without any parameters, in which case it displays the current date: If no year has been specified, it displays the current year
{{ISO date|Aug 17}}returns 2024-08-17{{ISO date}}returns 2024-05-19
The template accepts one unnamed parameter containing a date in one of the following formats:
{{ISO date|15 January 2001}}returns 2001-01-15{{ISO date|15 Jan 2001}}returns 2001-01-15{{ISO date|15-01-2001}}returns 2001-01-15
{{ISO date|January 15, 2001}}returns 2001-01-15{{ISO date|Jan 15, 2001}}returns 2001-01-15{{ISO date|Jan. 15, 2001}}returns 2001-01-15{{ISO date|01/15/2001}}returns 2001-01-15
{{ISO date|January 2001}}returns 2001-01{{ISO date|Jan 2001}}returns 2001-01
{{ISO date|2001}}returns 2001
Formats for which it can not work because #time returns an error or an incorrect ISO format:
{{ISO date|01-15-2001}}returns Error: Invalid time. (hyphens indicate DD-MM-YYYY and 15 is an invalid month number){{ISO date|15/01/2001}}returns Error: Invalid time. (slashes indicate MM/DD/YYYY and 15 is an invalid month number){{ISO date|1/2001}}returns Error: Invalid time.{{ISO date|2001 January 15}}returns Error: Invalid time.{{ISO date|2001 January}}returns 2001-01-01 (expected: 2001-01)
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:
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
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.
