Usage[change source]

These templates ({{Start date}} and {{End date}}) return a date, or date-time, duplicated in a hidden ISO date format, which degrades gracefully when CSS is not available.

Syntax[change source]

  • {{Start date|year|month|day}}
  • {{Start date|year|month|day|HH|MM|SS|TimeZone}} (MM and SS are optional; TimeZone may be a numerical value, or "Z" for UTC; see examples)
Examples
  • {{Start date|1993}} returns "1993 (1993)"
  • {{Start date|1993|02}} returns "February 1993 (1993-02)"
  • {{Start date|1993|02|24}} returns "February 24, 1993 (1993-02-24)"
  • {{Start date|1993|02|24|08|30}} returns "08:30, February 24, 1993 (1993-02-24T08:30)"
  • {{Start date|1993|02|24|08|||+01:00}} returns "February 24, 1993 (+01:00) (1993-02-24T08+01:00)"
  • {{Start date|1993|02|24|08|||-07:00}} returns "February 24, 1993 (-07:00) (1993-02-24T08-07:00)"
    {{Start date|1993|02|24|08|30|23}} returns "08:30:23, February 24, 1993 (1993-02-24T08:30:23)"
  • {{Start date|1993|02|24|08|30|23|Z}} returns "08:30:23, February 24, 1993 (UTC) (1993-02-24T08:30:23Z)"
  • {{Start date|1993|02|24|08|30|23|+01:00}} returns "08:30:23, February 24, 1993 (+01:00) (1993-02-24T08:30:23+01:00)"
  • {{Start date|1993|02|24|08|30|23|-07:00}} returns "08:30:23, February 24, 1993 (-07:00) (1993-02-24T08:30:23-07:00)"

An optional parameter, df, can be set to "y" or "yes" (or indeed any value) to display the day before the month. This is primarily used in articles about events in parts of the world where the day precedes the month in a date.

Examples
  • {{Start date|1993|02|24|df=y}} returns "24 February 1993 (1993-02-24)"
  • {{Start date|1993|02|24|08|30|df=yes}} returns "08:30, 24 February 1993 (1993-02-24T08:30)"

Note: The template will appear broken when the parameters are left blank (as seen hereinbefore).

Use in microformats[change source]

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 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 en:WP:UF for further details.

Limitation[change source]

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.
