Template:Age in years and days textual version/doc

Usage
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 WikiQueer:Age calculation templates for more information on using this kind of template.


 * Syntax :
 * or


 * Examples :
 * returns "13 years, 359 days"
 * returns ""
 * returns ""


 * Note :
 * This template does not check for incorrect input:
 * returns "" (surplus days do not count as extra months)
 * returns "" (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:
 * returns ""

but split up:
 * returns ""
 * returns ""
