Template:Start date and years ago/doc

This template shows the date of establishment of an institution, company etc. and its age in years.

This template should not be used for the date of birth or death of people, use birth date and age or death date and age instead.

'''The template requires "YYYY|MM|DD" parameters. Do not use for "YYYY" nor "YYYY|MM" dates.'''

Usage
will give Month D, YYYY (XX years ago)

Month First (mf) and Day First (df) options
The df (day first) and mf (month first) parameters indicate the intended date format to display. The appropriate parameter should be set to "y" or "yes" e.g. df=yes or mf=y.

The default output of this template is to display the month before the day (American format). This default may not be appropriate articles about people from parts of the world where the day precedes the month in a date (British/International format). In such articles the parameter, "df", should be set to display the day before the month.

The parameter "mf", while not actually used by the template, will indicate that month first format is intended. Using these parameters can assist bots or other automated processing to detect which date format is intended; leaving the format as default may lead an editor or bot to change the format to an unintended value.

Do not specify both "df" and "mf" parameters in the same use of the template, as these formats are mutually exclusive.

Hard return
When you want the "(# years ago)" to start at the next line rather than letting it soft-return, use the "br=1" parameter to hard-return it.
