Template:Age in years and days/doc
| This is a documentation subpage for Template:Age in years and days (see that page for the template itself). It contains usage information, categories and other content that is not part of the original template page. |
This template returns the number of full years and surplus days between two specified dates. If the second set of parameters is not included, it will return the number of full years and surplus days between a specified date and today's date. The two numbers are separated by a comma; the words "year" and "day" are plural when appropriate. The {{number table sorting}} template is included in the year value, so that values produced by this template will work properly in sortable lists. See Wikipedia:Age calculation templates for more information on using this kind of template.
Syntax[edit source]
{{Age in years and days|yyyy|mm|dd}}or{{Age in years and days|yyyy|mm|dd|yyyy2|mm2|dd2}}
Examples[edit source]
{{Age in years and days|1989|07|23}}returns "Template:Number table sorting/error years, Template:Number table sorting/error days"{{Age in years and days|1989|07|23|2003|07|24}}returns "Template:Number table sorting/error years, Template:Number table sorting/error days"
Notes[edit source]
This template does not check for incorrect input:
{{Age in years and days|1980|07|14|1993|06|233}}returns "Template:Number table sorting/error years, Template:Number table sorting/error days" (surplus days do not count as extra months){{Age in years and days|1980|07|14|1993|88|14}}returns "Template:Number table sorting/error years, Template:Number table sorting/error days" (surplus months do not count as extra years)
Also note that due to leap years, the measure "years and days" fails to be fully additive. The following example is not an error, but each calculation uses a different definition of "year", either 365 days or 366:
{{Age in years and days|2007|02|27|2008|03|02}}returns "Template:Number table sorting/error years, Template:Number table sorting/error days"
but split up:
{{Age in years and days|2007|02|27|2007|03|02}}returns "Template:Number table sorting/error years, Template:Number table sorting/error days"{{Age in years and days|2007|03|02|2008|03|02}}returns "Template:Number table sorting/error years, Template:Number table sorting/error days"
