Syntax[]
{{Birth date and age|year of birth|month of birth|day of birth|additional parameters}}
This form is only intended for living persons. In the rare case that a living person's birth date is given in a non-Gregorian calendar this template should not be used. The parameter names 'year', 'month', and 'day' can be used instead of the first, second, and third parameters for 'Birth date and age' only. These parameter names are not available for the 'Birth date' template.
Examples:
{{Birth date and age|1993|2|4|mf=yes}}returns February 4, 1993 (age 31){{Birth date and age|1993|2|4|df=yes}}returns 4 February 1993 (age 31){{Birth date and age|1993|2|24|mf=yes}}returns February 24, 1993 (age 31){{Birth date and age|1993|2|24|df=yes}}returns 24 February 1993 (age 31)
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 for 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", 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.
Examples:
{{Birth date and age|1993|2|24|df=yes}}displays "24 February 1993 (age 31)".
{{Birth date and age|1993|2|24|mf=yes}}displays "February 24, 1993 (age 31)".
hCard microformat[]
The templates also returns the date, hidden by CSS, in the ISO 8601 format (but not necessarily to the ISO 8601 standard) needed by hCard microformats. for example:
(<span class="bday">1993-02-24</span>)
See the microformats project for details.
