Using this template rather than simply inserting the date into articles allows for the inclusion of hidden [[metadata]] about the date. This metadata can be used by web browsers and other software tools to extract the details, and display them using some other website or mapping tool, index or search them.

===Month First (mf) and Day First (df) options===
===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. This default may not be appropriate articles about people from parts of the world where the day precedes the month in a date. In such articles the optional parameter, "df", can be set (to "y" or "yes" for example) to display the day before the month. Conversely the parameter "mf" can be set for month first, currently the default behaviour.
The default output of this template is to display the month before the day. This default may not be appropriate articles about people from parts of the world where the day precedes the month in a date. In such articles the parameter, "df", should be set to display the day before the month.
 
The parameter "mf" will indicate that month first format is intended. Using these parameters can assist [[WP:BOT|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.
