Template:Age in years, months and days

some time

Template documentation

This template uses (or will be using) Lua programming language. Please see Wikipedia:Lua if you want to learn more about Lua or help convert other templates.

This template returns the number of full years, then surplus months, then surplus days between two specified dates. If the second set of parameters is not included, it will return the number of years, months and days between a specified date and today's date. The words "year", "month" and "day" are plural when appropriate.

The years and months are separated by a comma. Since serial commas are optional and use varies, this template does not automatically place a comma after the months. If a serial comma is desired, adding |sc=y to the template invocation will include one.

See Wikipedia:Age calculation templates for more information on using this kind of template.

Usage

{{Age in years, months and days|year= |month= |day= }} or

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

Examples

{{Age in years, months and days|year=2001|month=1|day=15}} returns "23 years, 3 months, 12 days"

{{Age in years, months and days|2001|01|15|2008|09|05}} returns "7 years, 7 months, 21 days"

{{Age in years, months and days|2016|8|4|2016|9|5}} returns " 1 month,  1 day"

Notes

This template can handle an ambiguous start date:

{{Age in years, months and days|year=2010|month=9}} returns "13 years, {{{2}}} months, {{{3}}} days and 6 or {{{1}}} years, 7 months, {{{3}}} days"

{{Age in years, months and days|2009|6||2011|2|21}} returns "1 year, {{{2}}} months, {{{3}}} days and 7 or {{{1}}} years, 8 months, {{{3}}} days"

But it cannot handle an ambiguous end date:

{{Age in years, months and days|2012|11|2|2016|4}} returns "3 years, 5 months, 25 days"

{{Age in years, months and days|2012|11|2|2017}} returns "4 years, 5 months, 25 days"

Since the length of a month varies, the number of days to roll over the number of months varies.

{{Age in years, months and days|2007|3|12|2015|6|11}} returns "8 years, 2 months, 30 days"

{{Age in years, months and days|2007|3|12|2015|7|11}} returns "8 years, 3 months, 29 days"

To add a serial comma specify |sc=y.

{{Age in years, months and days|year=2001|month=1|day=15|sc=y}} returns "23 years, 3 months, 12 days"

{{Age in years, months and days|2001|1|15|2008|9|5|sc=y}} returns "7 years, 7 months, 21 days"

{{Age in years, months and days|2016|04|13|sc=y}} returns "8 years 14 days"
