== Usage ==
This template calculates a person's current age based on a known age as of specified date. This is useful when a reference states a person's age at the time of the reference's publication.

{{tlx|Age as of date|age|year|month|day}}

The age, year, and day must be supplied as [[natural number]]s; month can be specified as a natural number as well as by name or abbreviation (e.g., "August" or "Aug").  The [[Gregorian calendar]] is assumed, with no special support provided for [[dual dating]] or the difference between [[Old Style and New Style dates]] .

If a reference dated July 4, {{#expr: {{CURRENTYEAR}} - 2}}, mentions that someone is 50 years old, that person's current age can be rendered using:

{{tlx|Age as of date|50|{{#expr: {{CURRENTYEAR}} - 2}}|July|4}}
