The '''{{tl|Start date and age}}''' template displays the date that an event or entity started or was created. It also includes a duplicate, machine-readable date in the [[ISO 8601]] format (which is hidden by [[CSS]]), for use inside other templates which emit [[microformat]]s. The hidden date degrades gracefully when CSS is not available.
== Usage ==
;Common usage
: <code><nowiki>{{Start date and age|yyyy|mm|dd}}</nowiki></code> to display formatted as:
: {{xt|{{Start date and age|2010|03|25}}}}
: <code><nowiki>{{Start date and age|yyyy|mm|dd|df=yes}}</nowiki></code> to display formatted as:
: {{xt|{{Start date and age|2010|03|25|df=yes}}}}
;Full syntax
: <code><nowiki>{{Start date and age|yyyy|mm|dd|df=yes|p=yes|br=yes}}</nowiki></code> to display formatted as:
: {{xt|{{Start date and age|2010|03|25|df=yes|p=yes|br=yes}}}}
== Parameters ==
{| class="wikitable"
! Parameter
! Status
! Description
|-
| 1
| required
| A four-digit number indicating the year.
|-
| 2
| optional
| A number between 1 and 12 indicating the month (leading zeros in the number are ignored). The month may also be specified as a name or abbreviation (e.g. "August" or "Aug").
|-
| 3
| optional
| A number between 1 and 31 indicating the day of the month (leading zeros in the number are ignored).
|-
| df=
| optional
| If the parameter '''df''' equals '''yes''', '''y''', or '''1''', the date will be displayed in DMY format: {{xt|4 March 2010}}. When this parameter is not included or set to some other value, the date will be displayed in MDY format: {{xt|March 4, 2010}}.
|-
| p=<br/>paren=
| optional
| If the parameter '''p''' or '''paren''' equals '''yes''', '''y''', or '''1''', the age will be displayed within parentheses. When this parameter is not included or set to some other value, the date and age are separated by a semicolon and a breaking space.
|-
| br=
| optional
| If the parameter '''br''' equals '''yes''', '''y''', or '''1''', a line break will be inserted between the date and the age. When this parameter is not included or set to some other value, a breaking space will be inserted between the date and the age. This does not change the separating characters between the date and age which are either a semicolon (default setting) or parentheses (if '''p=yes''').
|}
==="df" (day first) and "mf" (month first)===
The default output of this template is to display the month before the day (MDY). This default may not be appropriate for articles about events or entities in parts of the world where dates are commonly given with the day preceding the month (DMY). To display the day first, assign the '''df''' parameter a value of '''yes''', '''y''', or '''1''' (e.g. '''df=yes''').
If the default format is preferred, the parameter '''df''' may be used with value of '''no''', '''n''', or '''0''' (e.g. '''df=no'''). These values can assist [[WP:BOT|bots]] or other automated processing to detect the intended date format; omitting the '''df''' parameter may lead an editor or bot to change the format to an unintended value.
The preference to display the month first may also be indicated via the parameter '''mf''' (e.g. '''mf=yes'''). While not actually used by the template, this is another method of indicating that the default format is intended. Do not specify both "df" and "mf" parameters in the same use of the template.
