Template documentation[view] [edit] [history] [purge]

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 2025-08-17
  • {{ISO date}} returns 2025-09-05

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

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
