Template:Age/doc

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

Usage

This template returns the number of full years between two specified dates. If the second set of parameters is not included, it returns the number of full years between a specified date and today's date.

Dates are checked for validity. For example, 29 February 2000 is accepted, but 29 February 1900 is not a valid date.

Partial dates such as July 1989 (no day) or 1989 (no month and no day) can be entered using 0 for missing values. Having no year, or having a day with no month is an error.

Please remember to avoid phrasings such as "17 years ago" or "Jones is 65 years old", even when they use this template. See MOS:RELTIME for more information.

Syntax

{{age|year|month|day|year2|month2|day2}} or

{{age|year|month|day}} or

{{age|date|date2}} or

{{age|date}}

Examples

{{age|1989|7|23|2003|7|14}} → 13

{{age|1989|7|0|2003|7|14}} → 14

{{age|1989|0|0|2003|7|14}} → 14

{{age|1989|7|23}} → 35

{{age|23 July 1989|14 July 2003}} → 13

{{age|July 1989|2003}} → 14

When entering dates before the Common Era, use astronomical year numbering: 1 BCE is represented by 0, 2 BCE by -1, 3 BCE by -2 etc. For example, the following gives the number of full years since the battle of Cannae, which took place on August 2, 216 BCE:

{{age|-215|8|2}} → 2239

{{age|August 2, 216 BCE}} → 2239

The options described at Module:Age can be used, for example:

{{age|-215|8|2}} → 2,239

{{age|1970|1|1|1998|2|1}} → twenty-eight

{{age|1970|1|1|1998|2|1}} → twenty-eighth

When only one date is entered, the current date is used for the other date. The template outputs a span that can be used by a calling infobox to detect if only one date was used. The following shows two examples with the exact wikitext that is produced, as seen at ExpandTemplates:

{{age|2010}} → <span class="currentage"></span>14

{{age|2010}} → 14
