This documentation is transcluded from Template:ISOdate/doc.

For a calendar date in ISO 8601 extended format in the form YYYY-MM-DD (e.g. "2024-07-20"), with or without time, this template extracts the year, month, day and time, and calls {{Date}} with the year, month and day found to display the date in localised format, with the time, if specified, appended. It provides the convenience of passing on a date (or even a date and a time) from one template to another as a single parameter, even though {{Date}} eventually needs the date components separately.

This template overcomes some flaws of the automatic conversion by {{#time: }} for non-full dates (e.g. "77-09" for September 77 AD, which would throw an error with {{#time: }}).

Template parameters

dateAny proleptic Gregorian calendar or Gregorian calendar date between 1 January 1 AD and 31 December 9999 AD. Dates BC are not yet supported. Also incomplete dates are allowed: just the year or the year and the month. A year has to be written in full, without leading zeros. Optionally it is followed by hyphen-minus (-) and a 2-digit month number; optionally this is followed by hyphen-minus and a 2-digit day number; optionally this is followed by the time.emptyrequired
languagelanguage code (only needs to be provided if the language shall be fixed and independent from the user's preferences)language code of the user language ({{int:Lang}})optional
casecaseallows to specify grammatical case for the month for languages that use them. Possible cases:
  • leave blank for default case, which is usually nominative in most languages or genitive case, for a date given in isolation (out of a sentence).
  • "case=nom" for the nominative case (for many languages with distinctive grammatical cases, for languages without case distinctions, this is the only existing form)
  • "case=gen" for the genitive case (supported for languages with distinctive grammatical cases)
  • "case=loc" for the locative case (supported for languages: pl, cs, sl)
  • "case=ins" for the instrumental case (supported for languages: ru, pl, cs, sl)
  • "case=ptv" for the partitive case (supported for language: fi)
  • "case=ine" for the inessive case (supported for language: fi)
  • "case=ela" for the elative case (supported for language: fi)
  • "case=ill" for the illative case (supported for language: fi)
classclassallows to set the html class of the time node where the date is included. This is useful for microformats. The default value is, for legacy reasons, "dtstart" (used by hCalendar). See the microformats project. "class=-" or "class=" will remove all metadata.dtstartoptional
trim year
trim yearShould years smaller than 1000 be padded with zeros to the length of 4 digits or trimmed. Options:
  • 1, yes, true - for always trimming
  • 0, no, false - for always padding
  • xx-yy - where xx is a minimum trimmed year and yy is the maximum trimmed year, for conditional trimming which depends on the year range.
  • 100-999optional
