User:Habst/Birth date and age in years and days

Documentation[view] [edit] [history] [purge]

Shortcut

• {{bdaydTemplate:Bdayd}}

This template uses Lua: Module:Age (sandbox)

User:Habst will return a living person's date of birth and age in years and days. 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.

This template is intended for use in an article about a living person. For an article about a dead person, use {{Birth date}} with {{Death date and age}}.

Is the displayed age incorrect? The age displayed was calculated when the page was last purged. If a particular article is showing the wrong age, edit the whole page and publish the edit without making any change and with no edit summary. That will update the age. The page can also be purged by appending &action=purge to the URL.

Usage

Unnamed parameters for year, month, day

{{Birth date and age|year, month, and day of birth}}

Error tracking

Some kinds of invalid input are tracked in Category:Pages using age template with invalid date.

Also see Category:Pages using birth date and age template with unknown parameters (0).

hCard microformat

This template also returns the date, hidden by CSS, in the ISO 8601 standard.^{[1] [2]} For example:

(<span class="bday">1993-02-24</span>)

Note: For the "foundation", "built" and similar set-up dates of companies, buildings etc., use {{start date}} (this will work for year-only or month-year dates). Because the ISO 8601 standard requires the Gregorian calendar, this template should not be used if the date is given in the Julian calendar.

For further information, visit the microformats project.

Notes

• The template will appear broken when the parameters are left blank.
• When only the year of a person's birth is known, or if it is desired not to state a person's full dates of birth for privacy reasons, consider using the templates {{Birth year}} or {{Birth year and age}} instead.

Examples

Output format

{{Birth date and age in years and days|1993-2-24}} returns "24 February 1993 (32 years, 188 days old)"
