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 the word "and"; 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.

Syntax
{{Age in years and days (textual) |year1|month1|day1 |year2|month2|day2}}
{{Age in years and days (textual) |year1|month1|day1}} (which then uses the current date as the second date)
Examples
{{Age in years and days (textual) |1989|07|23 |2003|07|14}} returns:  ೧೩ years and ೩೫೬ days

Note that this template does not check for incorrect input:

Red XN {{Age in years and days (textual) |1980|07|14 |1993|06|233}} returns:  Error: Error: Second date should be year month day This is not a valid number. Please refer to the documentation at {{Number table sorting}} for correct input. years and Error: Error: Second date should be year month day This is not a valid number. Please refer to the documentation at {{Number table sorting}} for correct input. days  (surplus days do not count as extra months)
Red XN {{Age in years and days (textual) |1980|07|14 |1993|88|14}} returns:  Error: Error: Second date should be year month day This is not a valid number. Please refer to the documentation at {{Number table sorting}} for correct input. years and Error: Error: Second date should be year month day This is not a valid number. Please refer to the documentation at {{Number table sorting}} for correct input. days  (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 (textual) |2007|02|27 |2008|03|02}} returns:  ೧ year and ೪ days

When split:

{{Age in years and days (textual) |2007|02|27 |2007|03|02}} returns:  ೦ years and ೩ days
{{Age in years and days (textual) |2007|03|02 |2008|03|02}} returns:  ೧ year and ೦ days
