Editing साँचा:Start date and age/doc

The  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 microformats. The hidden date degrades gracefully when CSS is not available.

 Usage 
Common usage
 {{Start date and age|yyyy|mm|dd}} to display formatted as:

 {{Start date and age|yyyy|mm|dd|df=yes}} to display formatted as:


Full syntax
 {{Start date and age|yyyy|mm|dd|df=yes|p=yes|br=yes}} to display formatted as:


 Parameters 
 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: . When this parameter is not included or set to some other value, the date will be displayed in MDY format: . p=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). end= optional This template includes hidden microformat , similar to Template:Start date. If the parameter end equals yes, y, or 1, the template will instead use , similar to Template:End date. This parameter is used by Template:End date and age. For more details, see Wikipedia:WikiProject Microformats. 

"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 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.

 Examples 
 Default separator: semicolon 
 Syntax Result Full date (year, month, day)             100 days ago:  Yesterday:  Today:  Year and month         Year only  

 Optional separator: parentheses 
 Syntax Result Full date (year, month, day)     Year and month   Year only  

 Line break with semicolon 
 Syntax Result Full date (year, month, day)     Year and month   Year only  

 Line break with parentheses 
 Syntax Result Full date (year, month, day)     Year and month   Year only  

 Use in microformats 

 Example 

Usage in articles
This template is most often used in infoboxes in articles about buildings or organizations, identifying when they were started/founded/opened or dissolved/ended/closed.

It has also been used for naval ships to indicate their commissioned age; however, several Wikipedia editors have reverted such edits. Use of this template in ship articles is therefore not recommended.

 Supporting templates 
 Template:MONTHNAME – display name of month for a given number 1 (January) through 12 (December).
 Template:Time ago – display number of days, months, or years ago (for dates given as |yyyy|mm|dd).
 Template:Years or months ago – display number of months or years ago (for dates given as |yyyy|mm or |yyyy).
 Template:Yesno – allows optional formatting parameters to accept values other than "yes" (such as "y" or "1").
