Template:Age as of date/doc
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.
{{Age as of date|14|2010|March|3}}
The age, year, and day must be supplied as W:natural numbers; month can be specified as a natural number as well as by name or abbreviation (e.g., "August" or "Aug"). The W:Gregorian calendar is assumed, with no special support provided for W:dual dating or the difference between W:Old Style and New Style dates .
If a reference dated July 4, 2022, mentions that someone is 50 years old, that person's current age can be rendered using:
{{Age as of date|50|{{#expr: {{CURRENTYEAR}} - 2}}|July|4}}
