Module:Age/doc

	This is a documentation subpage for Module:Age. It contains usage information, categories and other content that is not part of the original module page.

Templates supported

Module:Age implements the following templates:

Template	Required wikitext
{{age}}	{{#invoke:age|age_generic|template=age_full_years}}
{{age in years and months}}	{{#invoke:age|age_generic|template=age_ym}}
{{birth date and age}}	<strong class="error">Error: Need valid birth date: year, month, day</strong>
{{death date and age}}	<strong class="error">Error: Need valid death date (first date): year, month, day</strong>

Redirects

Template	Redirects to
{{Bda}}	{{birth date and age}}
{{Dda}}	{{death date and age}}

The age templates expect the older date to be first. The implementations of age_in_years display an error message if that is not the case. If similar checking is wanted for other templates, |negative=error can be added to the invoke. For example, {{age}} might use:

{{#invoke:age|age_generic|template=age_full_years|negative=error}}

If |negative=error 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:

• {{age in years and months}} → 11 years, 1 month
• {{age in years and months}} → 11 years, 1 month
• {{age in years and months|2001|1|10|2012|2|20}} → 11 years, 1 month
• {{age in years and months|2001-1-10|2012-2-20}} → 11 years, 1 month
• {{age in years and months|10 Jan 2001|20 Feb 2012}} → 11 years, 1 month
• {{age in years and months|January 10, 2001|Feb 20, 2012}} → 11 years, 1 month

If the first or second date is omitted, the current date is used. For example:

• {{age in years and months}} → −12 years, 9 months
• {{age in years and months|2012|2|20}} → −12 years, 9 months
• {{age in years and months|2012-2-20}} → −12 years, 9 months
• {{age in years and months|20 Feb 2012}} → −12 years, 9 months
• {{age in years and months|Feb 20, 2012}} → −12 years, 9 months
• {{age in years and months}} → 23 years, 10 months
• {{age in years and months}} → 23 years, 10 months
• {{age in years and months|2001|1|10}} → 23 years, 10 months
• {{age in years and months|2001-1-10}} → 23 years, 10 months
• {{age in years and months|10 Jan 2001}} → 23 years, 10 months
• {{age in years and months|January 10, 2001}} → 23 years, 10 months

Parameters

The following options are available:

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

Examples using the |range= parameter follow.

• {{age in years and months}} → 11 years, 0 or 1 month
• {{age in years and months|2001|1|2012|2}} → 11 years, 0 or 1 month
• {{age in years and months|Jan 2001|Feb 2012}} → 11 years, 0 or 1 month
• {{age in years and months|Jan 2001|Feb 2012}} → 11 years, 0–1 month
• {{age in years and months|Jan 2001|Feb 2012}} → 11 years, 1 month assume 1 Jan 2001 to 1 Feb 2012
• {{age in years and months|12 Jan 2001|Feb 2012}} → 11 years, 1 month assume 12 Jan 2001 to 12 Feb 2012
• {{age in years and months|2001|2012}} → 11 years assume 1 Jan 2001 to 1 Jan 2012
• {{age in years and months|2001|23 Feb 2012}} → 11 years 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.

• {{age in years and months|10 Jan 2001|20 Feb 2012}} → 7003405800000000000♠11 years, 1 month
• {{age in years and months|10 Jan 2001|6:00 am 20 Feb 2012}} → 7003405825000000000♠11 years, 1 month
• {{age in years and months|10 Jan 2001|6:00 am 20 Feb 2012}} → 7003405825000000000♠

An extra day is added for a duration.

• {{age in years and months|20 Jan 2001|19 Feb 2012}} → 11 years one day short of 11 years, 1 month
• {{age in years and months|20 Jan 2001|19 Feb 2012}} → 11 years, 1 month

The least-significant time unit can be rounded.

• {{age in years and months|20 Jan 2001|10 Feb 2012}} → 11 years
• {{age in years and months|20 Jan 2001|10 Feb 2012}} → 11 years, 1 month round to nearest month

Large numbers can be formatted with commas.

• {{age in years and months|120|2012}} → 1,891 or 1,892 years
• {{age in years and months|120|2012}} → 1,891–1,892 years

Spelling numbers

The templates that use age_generic can display numbers in words rather than using numerals. The result can be a cardinal number (such as "five") or an ordinal number (such as "fifth"). The first letter can be in uppercase, and US spelling of numbers can be used. Examples:

• {{age|1898|01|01|2018|02|01|format = cardinal}} → one hundred and twenty
• {{age|1898|01|01|2018|02|01|format = cardinal_us}} → one hundred twenty
• {{age|1898|01|01|2018|02|01|format = Cardinal}} → One hundred and twenty
• {{age|1898|01|01|2018|02|01|format = Cardinal_us}} → One hundred twenty
• {{{age|1898|01|01|2018|02|01|format = Ordinal}} → One hundred and twentieth
• {{age|1898|01|01|2018|02|01|format = Ordinal_us}} → One hundred twentieth
• {{age|1898|01|01|2018|02|01|format = ordinal}} → one hundred and twentieth
• {{age|1898|01|01|2018|02|01|format = ordinal_us}} → one hundred twentieth
• {{ge|1980|1990|format = Cardinal}} → Nine or ten
