Template:Birth date and age/doc

These templates ({{Birth date}} and {{Birth date and age}}) return a person’s date of birth and optionally his/her age.

Do NOT use this template when the person’s exact date of birth is disputed or unknown.

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.

Syntax

To display the birth date only

{{Birth date|year of birth|month of birth|day of birth|additional parameters}} Do not use with non-Gregorian dates because the resulting hCard hidden date will be false.

To display a birth date with calculated age

{{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|1993|02|04|df=yes}} returns "4 February 1993(1993-02-04)"

{{Birth date|1993|02|04|mf=yes}} returns "February 4, 1993(1993-02-04)"

{{Birth date|1993|02|24|df=yes}} returns "24 February 1993(1993-02-24)"

{{Birth date|1993|02|24|mf=yes}} returns "February 24, 1993(1993-02-24)"

{{Birth date and age|1993|02|04|mf=yes}} returns February 4, 1993 (1993-02-04)

{{Birth date and age|1993|02|04|df=yes}} returns 4 February 1993 (1993-02-04)

{{Birth date and age|1993|02|24|mf=yes}} returns February 24, 1993 (1993-02-24)

{{Birth date and age|1993|02|24|df=yes}} returns 24 February 1993 (1993-02-24)

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|1993|02|24|df=yes}} displays "24 February 1993(1993-02-24)".

{{Birth date and age|1993|02|24|df=yes}} displays "24 February 1993 (1993-02-24)".

{{Birth date|1993|02|24|mf=yes}} displays "February 24, 1993(1993-02-24)".

{{Birth date and age|1993|02|24|mf=yes}} displays "February 24, 1993 (1993-02-24)".
