| This is a documentation subpage for Template:Birth based on age as of date. It contains usage information, categories and other content that is not part of the original template page. |

You are encouraged to familiarise yourself with its setup and parser functions before editing the template. If your edit causes unexpected problems, please undo it quickly, as this template may appear on a large number of pages. You can conduct experiments, and should test all major changes, in either this template's sandbox, the general template sandbox, or your user space before changing anything here. |
This template calculates the birth year and current age based on the age as of a date. This is useful when a reference states only their age at the time of the reference's publication.
Syntax
{{birth based on age as of date |age |year|month|day}}
The age, year, and day must be supplied as natural numbers; 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 .
Options
To suppress the age field:
{{birth based on age as of date |age |year|month|day |noage=1}}
With the "noage=1" option, the month and day can be "1".
Examples
If, for example, a reference dated July 4, 2025 mentions that someone is 50 years old, that person's birth year and age can be rendered using:
{{birth based on age as of date |50 |2025|July|4}}
|
The following examples use a date which is one year before 18 January 2026 |
