Template:Start date/doc

Usage

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

{{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)

or

{{End date|year|month|day}}

Examples:

{{Start date|1993}} returns "1993 (1993)"

{{Start date|1993|2}} returns "February 1993 (1993-02)"

{{Start date|1993|2|24}} returns "February 24, 1993 (1993-02-24)"

{{Start date|1993|2|24|08|30}} returns "08:30, February 24, 1993 (1993-02-24T08:30)"

{{Start date|1993|2|24|08|||+01:00}} returns "February 24, 1993 (+01:00) (1993-02-24T08+01:00)"

{{Start date|1993|2|24|08|||-07:00}} returns "February 24, 1993 (-07:00) (1993-02-24T08-07:00)"

{{Start date|1993|2|24|08|30|23}} returns "08:30:23, February 24, 1993 (1993-02-24T08:30:23)"

{{Start date|1993|2|24|08|30|23|Z}} returns "08:30:23, February 24, 1993 (UTC) (1993-02-24T08:30:23Z)"

{{Start date|1993|2|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|2|24|08|30|23|-07:00}} returns "08:30:23, February 24, 1993 (-07:00) (1993-02-24T08:30:23-07:00)"

{{End date|1993|2|24}} returns "Template:End date"

{{End date|1993|2|24|08|30}} returns "Template:End date"

An optional parameter, df, can be set to "yes" 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|2|24|df=yes}} returns "24 February 1993 (1993-02-24)"

{{Start date|1993|2|24|08|30|df=yes}} returns "08:30, 24 February 1993 (1993-02-24T08:30)"

{{End date|1993|2|24|df=yes}} returns "Template:End date"

(users who have already set date preferences will need to be logged out to see the difference).

{{Start date}} also returns the date, hidden by CSS, in the ISO 8601 format needed by hAtom (class="updated") and hCalendar (class="dtstart") microformats. Similarly, {{End date}} returns the date as hCalendar's (class="dtend"). For example:

(<span class="dtstart updated">1993-02-24</span>) and (<span class="dtstart updated">1993-02-24T08:30</span>)

and:

(<span class="dtend">1993-02-24T08:30</span>)

(disable CSS or view source to see the ISO-formatted output).

'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 28 March 1999 (1999-03-29) or even 28 February 1999 (1999-03-01) or 31 December 1999 (2000-01-01), the Date end template should not be used for whole-day dates and should have a time of 23:59:59.

See the microformats project for details.

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