Documentation icon Template documentation[view] [edit] [history] [purge]

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.

Entering full dates as parameters[edit]

Syntax[edit]

{{Age in years and days|date}} or
{{Age in years and days|date 1|date 2}}

Examples[edit]

{{Age in years and days|15 May 2010}} returns "5 years,   7 days"
{{Age in years and days|12 Aug 2003|24 Sep 2011}} returns "8 years,  43 days"

Entering year, month and day[edit]

Syntax[edit]

{{Age in years and days|yyyy|mm|dd}} or
{{Age in years and days|yyyy|mm|dd|yyyy2|mm2|dd2}}

Examples[edit]

{{Age in years and days|1989|07|23}} returns "25 years, 303 days"
{{Age in years and days|1989|07|23|2003|07|24}} returns "14 year, 1 day"

Note[edit]

This template does not check for incorrect input when entering year, month and day.

{{Age in years and days|1980|07|14|1993|06|233}} returns "12 years, 554 days" (surplus days do not count as extra months)
{{Age in years and days|1980|07|14|1993|88|14}} returns "13 years, 2471 days" (surplus months do not count as extra years)

Using "and" as separator[edit]

The default is to separate years and days using a comma. To use "and" instead use |sep=and.

{{Age in years and days|October 13, 1993|November 20, 2000|sep=and}} returns "7 years and 38 days"

Note[edit]

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 "1 years, 4 days"

but split up:

{{Age in years and days|2007|02|27|2007|03|02}} returns "3 days"
{{Age in years and days|2007|03|02|2008|03|02}} returns "1 years, 0 days"
