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.

## Parameters

### "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  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

### Optional separator: parentheses

### Line break with semicolon

### Line break with parentheses

## 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
