Teamplaid:Death date and age

This template is used on 80,000+ pages, and changes to it will be widely noticed. Please test any changes in the template's /sandbox or /testcases subpages, or in a user subpage, and consider discussing changes at the talk page before implementing them.

Returns a person's date of death and age at that date. Available shortcut: {{Dda}}.

Do NOT use this template when the person's exact date of birth or death is disputed or unknown. Consider {{Death year and age}} instead.

The idea of using the template, like with {{Birth date and age}} etc, is to allow for the inclusion of hidden metadata to be used, indexed or searched by software tools. However, as of October 2008 this template does not include any such metadata and never has since it was founded in December 2006. The apparent reason is that the hCard microformat, logically enough for an extension of "standard for electronic business cards", contains only "BDAY" field but nothing to do with a death. It is unclear when metadata standard for the dead will be developed and adopted. Until then, the template does nothing but format the input parameters.

Syntax

To display the death date with age

{{Death date and age|year of death|month of death|day of death|year of birth|month of birth|day of birth|additional parameters}}

Format: {{Death date and age|yyyy|mm|dd|yyyy|mm|dd|df=yes}}; {{Death date and age|yyyy|mm|dd|yyyy|mm|dd|mf=yes}}

Using the Dda shortcut

{{Dda|yyyy|mm|dd|yyyy|mm|dd|df=yes}}

{{Dda|yyyy|mm|dd|yyyy|mm|dd|mf=yes}}

Examples

{{Death date and age|1993|2|24|1941|4|12|df=yes}}
returns 24 February 1993 (aged 51)

{{Death date and age|1993|2|24|1941|4|12|mf=yes}}
returns February 24, 1993 (aged 51)

Note: The template will appear broken when the parameters are left blank.

Day First (df) and Month First options

The df (day first) parameter indicates the intended date format to display. It is switched on by setting it to "y" or "yes" e.g. df=yes or df=y.

The default output of this template is the month before the day (American-based style). This default may not be appropriate in articles about people from parts of the world where the day precedes the month in a date (e.g. Europe). In such cases the parameter df should be set.

It is possible to use similar parameter "mf" to stress the month-first format so that relying on the default does not lead an editor or bot to change the format to an unintended value; however, it is ignored by the template itself. (So, should both parameters be mistakenly used at once, df takes precedence.)

Examples:

{{Death date and age|1993|2|24|1941|4|12|df=yes}}
displays "24 February 1993 (aged 51)"

{{Death date and age|1993|2|24|1941|4|12|mf=yes}}
displays "February 24, 1993 (aged 51)"

Specific date unknown - alternate templates

When only the year of a person's birth and/or death are known, or if it is desired not to state a person's full dates of birth and death for privacy reasons, use the templates {{Birth year and age}} and {{Death year and age}} instead.

Interaction side-effects with other templates

Note: Do not use this template inside of the Persondata template as it can interfere with data extraction.

FAQ

Q: Why don't these templates add categories, such as "Births in [Year]" to articles on which they are used?
A: Because they are sometimes used for dates in lists of people, such as sports team members.
