{{A.y}}

Usage

Displays age in years and fractions of years. Dates can be entered in the format:

{{A.y|Start year|Start month|Start day|End year|End month|End day}}

or

{{A.y|Start date|End date}}

The |round= parameter can be used to set the number of decimal places shown (defaults to 1).

The |suffix= parameter can be used to set the suffix after the number (defaults to "years").

Examples

{{a.y|15 May 2010}} → 14.6 years
{{a.y|12 Aug 2003|24 Sep 2011}} → 8.1 years
{{a.y|1989|7|23}} → 35.4 years
{{a.y|1989|7|23|2003|7|24}} → 14 years
{{a.y|1989|7|23|2003|7|24|round=3}} → 14.002 years
{{a.y|2007|03|02|2008|03|02|suffix=yr}} → 1 yr
