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.

Notes[golygu cod y dudalen]

This template does not check for incorrect input:

{{Age in years and days|1980|07|14|1993|06|233}} returns "700112000000000000012 blynedd, 7002554000000000000554 diwrnod" (surplus days do not count as extra months)
{{Age in years and days|1980|07|14|1993|88|14}} returns "700113000000000000013 blynedd, 70032471000000000002,471 diwrnod" (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 "70001000000000000001 mlynedd, 70004000000000000004 diwrnod"

but split up:

{{Age in years and days|2007|02|27|2007|03|02}} returns "50000000000000000000 blynedd, 70003000000000000003 diwrnod"
{{Age in years and days|2007|03|02|2008|03|02}} returns "70001000000000000001 mlynedd, 50000000000000000000 diwrnod"
