Template:Age in years and days/doc

From Simple English Wikipedia, the free encyclopedia

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 {{nts}} 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.

{{Age in years and days|year1|month1|day1|year2|month2|day2}} or
{{Age in years and days|year1|month1|day1}}
{{Age in years and days|1989|07|23|2003|07|14}} returns "13 years, 356 days"
{{Age in years and days|1989|07|23}} returns "34 years, 275 days"
{{Age in years and days|1989|07|23|1990|07|24}} returns "1 year, 1 day"
When using this template to calculate a person's age at death or a person's age on a specified date (rather than the person's current age), please substitute it into the page.
Example: {{subst:Age in years and days|1989|07|23|2003|07|14}}
This template does not check for incorrect input:
{{Age in years and days|1980|07|14|1993|06|233}} returns "Error: Second date should be year, month, day" (surplus days do not count as extra months)
{{Age in years and days|1980|07|14|1993|88|14}} returns "Error: Second date should be year, month, day" (surplus months do not count as extra years)

Note also 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 year, 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 year, 0 days"
