Module:Age/doc

This is the documentation page for Module:Age

This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing.

This Lua module is used on approximately 1,130,000 pages, or roughly 3018% of all pages.
To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them.

Redirects

Template	Redirects to
{{ayd}}	{{age in years and days nts}}
{{hla}}	{{age in years, months and days}}
{{age in months, weeks and days}}	{{age in years, months, weeks and days}}
{{bda}}	{{birth date and age}}
{{dda}}	{{death date and age}}
{{gsd}}	{{gregorian serial date}}

The age templates expect the older date to be first. The implementations of age_in_years and age_in_years_nts 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|year1=2001|month1=1|day1=10|year2=2012|month2=2|day2=20}} → Template:Age in years and months
{{age in years and months|year=2001|month=1|day=10|year2=2012|month2=2|day2=20}} → Template:Age in years and months
{{age in years and months|2001|1|10|2012|2|20}} → Template:Age in years and months
{{age in years and months|2001-1-10|2012-2-20}} → Template:Age in years and months
{{age in years and months|10 Jan 2001|20 Feb 2012}} → Template:Age in years and months
{{age in years and months|January 10, 2001|Feb 20, 2012}} → Template:Age in years and months

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

{{age in years and months|year2=2012|month2=2|day2=20}} → Template:Age in years and months
{{age in years and months||||2012|2|20}} → Template:Age in years and months
{{age in years and months||2012-2-20}} → Template:Age in years and months
{{age in years and months||20 Feb 2012}} → Template:Age in years and months
{{age in years and months||Feb 20, 2012}} → Template:Age in years and months
{{age in years and months|year1=2001|month1=1|day1=10}} → Template:Age in years and months
{{age in years and months|year=2001|month=1|day=10}} → Template:Age in years and months
{{age in years and months|2001|1|10}} → Template:Age in years and months
{{age in years and months|2001-1-10}} → Template:Age in years and months
{{age in years and months|10 Jan 2001}} → Template:Age in years and months
{{age in years and months|January 10, 2001}} → Template:Age in years and 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 (can override the default for a template like {{age nts}}).

Examples using the range parameter follow.

{{age in years and months|year=2001|month=1|year2=2012|month2=2|range=yes}} → Template:Age in years and months
{{age in years and months|2001|1||2012|2|range=yes}} → Template:Age in years and months
{{age in years and months|Jan 2001|Feb 2012|range=yes}} → Template:Age in years and months
{{age in years and months|Jan 2001|Feb 2012|range=dash}} → Template:Age in years and months
{{age in years and months|Jan 2001|Feb 2012|range=no}} → Template:Age in years and months Template:Green
{{age in years and months|12 Jan 2001|Feb 2012|range=no}} → Template:Age in years and months Template:Green
{{age in years and months|2001|2012|range=no}} → Template:Age in years and months Template:Green
{{age in years and months|2001|23 Feb 2012|range=no}} → Template:Age in years and months Template:Green

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|sortable=debug}} → Template:Age in years and months
{{age in years and months|10 Jan 2001|6:00 am 20 Feb 2012|sortable=debug}} → Template:Age in years and months
{{age in years and months|10 Jan 2001|6:00 am 20 Feb 2012|sortable=debug|show=hide}} → Template:Age in years and months

An extra day is added for a duration.

{{age in years and months|20 Jan 2001|19 Feb 2012}} → Template:Age in years and months Template:Green
{{age in years and months|20 Jan 2001|19 Feb 2012|duration=on}} → Template:Age in years and months

The least-significant time unit can be rounded.

{{age in years and months|20 Jan 2001|10 Feb 2012}} → Template:Age in years and months
{{age in years and months|20 Jan 2001|10 Feb 2012|round=on}} → Template:Age in years and months Template:Green

Large numbers can be formatted with commas.

{{age in years and months|120|2012|format=commas|range=yes}} → Template:Age in years and months
{{age in years and months|120|2012|format=commas|range=dash}} → Template:Age in years and months

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}} → Lua error in package.lua at line 80: module 'Module:ConvertNumeric' not found.
{{age|1898|01|01|2018|02|01|format=cardinal_us}} → Lua error in package.lua at line 80: module 'Module:ConvertNumeric' not found.

{{age|1980|1990|range=yes|format=Cardinal}} → Lua error in package.lua at line 80: module 'Module:ConvertNumeric' not found.
{{age in years, months and days|April 1980|1995|format=Cardinal|range=yes}} → Template:Age in years, months and days
