The age templates expect the older date to be first. The implementations of <code>age_in_years</code> and <code>age_in_years_nts</code> display an error message if that is not the case. If similar checking is wanted for other templates, <code>negative=error</code> can be added to the invoke. For example, {{tl|age}} might use:
*<code><nowiki>{{#invoke:age|age_generic|template=age_full_years|negative=error}}</nowiki></code>
If <code>negative=error</code> does not apply, a negative difference is indicated with a minus sign (−).

== Date formats ==
Dates can use numbered or named parameters to specify year/month/day. Alternatively, a full date can be entered in a variety of formats. For example:
*<code><nowiki>{{age in years and months|year1=2001|month1=1|day1=10|year2=2012|month2=2|day2=20}}</nowiki></code> → {{age in years and months|year1=2001|month1=1|day1=10|year2=2012|month2=2|day2=20}}
*<code><nowiki>{{age in years and months|year=2001|month=1|day=10|year2=2012|month2=2|day2=20}}</nowiki></code> → {{age in years and months|year=2001|month=1|day=10|year2=2012|month2=2|day2=20}}
*<code><nowiki>{{age in years and months|2001|1|10|2012|2|20}}</nowiki></code> → {{age in years and months|2001|1|10|2012|2|20}}
*<code><nowiki>{{age in years and months|2001-1-10|2012-2-20}}</nowiki></code> → {{age in years and months|2001-1-10|2012-2-20}}
*<code><nowiki>{{age in years and months|10 Jan 2001|20 Feb 2012}}</nowiki></code> → {{age in years and months|10 Jan 2001|20 Feb 2012}}
*<code><nowiki>{{age in years and months|January 10, 2001|Feb 20, 2012}}</nowiki></code> → {{age in years and months|January 10, 2001|Feb 20, 2012}}

If the first or second date is omitted, the current date is used. For example:
*<code><nowiki>{{age in years and months|year2=2012|month2=2|day2=20}}</nowiki></code> → {{age in years and months|year2=2012|month2=2|day2=20}}
*<code><nowiki>{{age in years and months||||2012|2|20}}</nowiki></code> → {{age in years and months||||2012|2|20}}
*<code><nowiki>{{age in years and months||2012-2-20}}</nowiki></code> → {{age in years and months||2012-2-20}}
*<code><nowiki>{{age in years and months||20 Feb 2012}}</nowiki></code> → {{age in years and months||20 Feb 2012}}
*<code><nowiki>{{age in years and months||Feb 20, 2012}}</nowiki></code> → {{age in years and months||Feb 20, 2012}}
*<code><nowiki>{{age in years and months|year1=2001|month1=1|day1=10}}</nowiki></code> → {{age in years and months|year1=2001|month1=1|day1=10}}
*<code><nowiki>{{age in years and months|year=2001|month=1|day=10}}</nowiki></code> → {{age in years and months|year=2001|month=1|day=10}}
*<code><nowiki>{{age in years and months|2001|1|10}}</nowiki></code> → {{age in years and months|2001|1|10}}
*<code><nowiki>{{age in years and months|2001-1-10}}</nowiki></code> → {{age in years and months|2001-1-10}}
*<code><nowiki>{{age in years and months|10 Jan 2001}}</nowiki></code> → {{age in years and months|10 Jan 2001}}
*<code><nowiki>{{age in years and months|January 10, 2001}}</nowiki></code> → {{age in years and months|January 10, 2001}}

== Parameters ==
The following options are available:
{| class="wikitable"
! Parameter !! Description
|-
| <code>duration=on</code> || The finishing date is included in the result; that adds one day to the age.
|-
| <code>fix=on</code> || Adjust invalid time units. See [[Template:Extract#Fix]].
|-
| <code>format=commas</code> || A value of 1,000 or more is displayed with commas.
|-
| <code>format=raw</code> || Numbers are displayed without commas and negative numbers are displayed with a hyphen for <code><nowiki>{{#expr}}</nowiki></code>. In addition, {{tl|age}} outputs a plain number and will not include a span to indicate if the result relies on the current date.
|-
| <code>format=cardinal</code> || Display the resulting number using words such as "five" instead of 5. See [[#Spelling numbers|below]].
|-
| <code>format=ordinal</code> || Display the resulting number using words such as "fifth" instead of 5. See [[#Spelling numbers|below]].
|-
| <code>prefix=''text''</code> || Insert the given ''text'' before the result but after any sort key. For example, <code><nowiki>{{age|23 July 1910|14 July 1976|prefix=about|sortable=on}}</nowiki></code> outputs a hidden sort key followed by "about 65".
|-
| <code>range=dash</code> || Accept a year only, or a year and month only, and show a range of ages with an [[Dash#En dash|en dash]] (–).
|-
| <code>range=yes</code> || Accept a year or year/month, and show the range with "or".
|-
| <code>range=no</code> || Accept a year only, or year/month, but show only a single age as if full dates had been entered.
|-
| <code>round=on</code> || The age is rounded to the nearest least-significant time unit.
|-
| <code>sc=on</code> || A [[serial comma]] is used (only useful when three or more values are displayed).
|-
| <code>sc=yes</code> || Same as <code>sc=on</code>.
|-
| <code>show=hide</code> || The age is not displayed; may be useful with <code>sortable=on</code>.
|-
| <code>sortable=on</code> || Insert a hidden sort key before the result (for use in [[WP:SORT|sortable tables]]).
|-
| <code>sortable=table</code> || Insert a sort key using table syntax <code>data-sort-value="''value''"&#124;</code>.
|-
| <code>sortable=debug</code> || Same as <code>sortable=on</code> but the sort key is displayed for testing.
|-
| <code>sortable=off</code> || No sort key (can override the default for a template like {{tl|age nts}}).
|}

Examples using the <code>range</code> parameter follow.
*<code><nowiki>{{age in years and months|year=2001|month=1|year2=2012|month2=2|range=yes}}</nowiki></code> → {{age in years and months|year=2001|month=1|year2=2012|month2=2|range=yes}}
*<code><nowiki>{{age in years and months|2001|1||2012|2|range=yes}}</nowiki></code> → {{age in years and months|2001|1||2012|2|range=yes}}
*<code><nowiki>{{age in years and months|Jan 2001|Feb 2012|range=yes}}</nowiki></code> → {{age in years and months|Jan 2001|Feb 2012|range=yes}}
*<code><nowiki>{{age in years and months|Jan 2001|Feb 2012|range=dash}}</nowiki></code> → {{age in years and months|Jan 2001|Feb 2012|range=dash}}
*<code><nowiki>{{age in years and months|Jan 2001|Feb 2012|range=no}}</nowiki></code> → {{age in years and months|Jan 2001|Feb 2012|range=no}} {{green|1=(assume 1 Jan 2001 to 1 Feb 2012)}}
*<code><nowiki>{{age in years and months|12 Jan 2001|Feb 2012|range=no}}</nowiki></code> → {{age in years and months|12 Jan 2001|Feb 2012|range=no}} {{green|1=(assume 12 Jan 2001 to 12 Feb 2012)}}
*<code><nowiki>{{age in years and months|2001|2012|range=no}}</nowiki></code> → {{age in years and months|2001|2012|range=no}} {{green|1=(assume 1 Jan 2001 to 1 Jan 2012)}}
*<code><nowiki>{{age in years and months|2001|23 Feb 2012|range=no}}</nowiki></code> → {{age in years and months|2001|23 Feb 2012|range=no}} {{green|1=(assume 23 Feb 2001 to 23 Feb 2012)}}

The sort key is based on the age in days, and fractions of a day if a time is specified.
*<code><nowiki>{{age in years and months|10 Jan 2001|20 Feb 2012|sortable=debug}}</nowiki></code> → {{age in years and months|10 Jan 2001|20 Feb 2012|sortable=debug}}

*<code><nowiki>{{age in years and months|10 Jan 2001|6:00 am 20 Feb 2012|sortable=debug|show=hide}}</nowiki></code> → {{age in years and months|10 Jan 2001|6:00 am 20 Feb 2012|sortable=debug|show=hide}}

An extra day is added for a duration.
*<code><nowiki>{{age in years and months|20 Jan 2001|19 Feb 2012}}</nowiki></code> → {{age in years and months|20 Jan 2001|19 Feb 2012}} {{green|1=(one day short of 11 years, 1 month)}}
*<code><nowiki>{{age in years and months|20 Jan 2001|19 Feb 2012|duration=on}}</nowiki></code> → {{age in years and months|20 Jan 2001|19 Feb 2012|duration=on}}

The least-significant time unit can be rounded.
*<code><nowiki>{{age in years and months|20 Jan 2001|10 Feb 2012}}</nowiki></code> → {{age in years and months|20 Jan 2001|10 Feb 2012}}
*<code><nowiki>{{age in years and months|20 Jan 2001|10 Feb 2012|round=on}}</nowiki></code> → {{age in years and months|20 Jan 2001|10 Feb 2012|round=on}} {{green|1=(round to nearest month)}}

Large numbers can be formatted with commas.
*<code><nowiki>{{age in years and months|120|2012|format=commas|range=yes}}</nowiki></code> → {{age in years and months|120|2012|format=commas|range=yes}}
*<code><nowiki>{{age in years and months|120|2012|format=commas|range=dash}}</nowiki></code> → {{age in years and months|120|2012|format=commas|range=dash}}

== Spelling numbers ==
The templates that use <code>age_generic</code> can display numbers in words rather than using numerals. The result can be a [[Cardinal number (linguistics)|cardinal number]] (such as "five") or an [[Ordinal number (linguistics)|ordinal number]] (such as "fifth"). The first letter can be in uppercase, and US spelling of numbers can be used. Examples:
*<code><nowiki>{{age|1898|01|01|2018|02|01|format=cardinal}}</nowiki></code> → {{age|1898|01|01|2018|02|01|format=cardinal}}
*<code><nowiki>{{age|1898|01|01|2018|02|01|format=cardinal_us}}</nowiki></code> → {{age|1898|01|01|2018|02|01|format=cardinal_us}}
*<code><nowiki>{{age|1898|01|01|2018|02|01|format=Cardinal}}</nowiki></code> → {{age|1898|01|01|2018|02|01|format=Cardinal}}
*<code><nowiki>{{age|1898|01|01|2018|02|01|format=Cardinal_us}}</nowiki></code> → {{age|1898|01|01|2018|02|01|format=Cardinal_us}}
*<code><nowiki>{{age|1898|01|01|2018|02|01|format=Ordinal}}</nowiki></code> → {{age|1898|01|01|2018|02|01|format=Ordinal}}
*<code><nowiki>{{age|1898|01|01|2018|02|01|format=Ordinal_us}}</nowiki></code> → {{age|1898|01|01|2018|02|01|format=Ordinal_us}}
*<code><nowiki>{{age|1898|01|01|2018|02|01|format=ordinal}}</nowiki></code> → {{age|1898|01|01|2018|02|01|format=ordinal}}
*<code><nowiki>{{age|1898|01|01|2018|02|01|format=ordinal_us}}</nowiki></code> → {{age|1898|01|01|2018|02|01|format=ordinal_us}}
*<code><nowiki>{{age|1980|1990|range=yes|format=Cardinal}}</nowiki></code> → {{age|1980|1990|range=yes|format=Cardinal}}
*<code><nowiki>{{age in years, months and days|April 1980|1995|format=Cardinal|range=yes}}</nowiki></code> → {{age in years, months and days|April 1980|1995|format=Cardinal|range=yes}}
