{{redirect3|noquotes|[[Template:Birth year from age at date]]}}
{{Intricate template}}

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===
<pre> {{birth based on age as of date |age|year|month|day}} </pre>
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 they are not known, the "day" and "month" fields can be omitted; this is useful if, for example, only the publication year for a source is known.

===Options===
To suppress the age field:
<pre> {{birth based on age as of date |age |year|month|day |noage=1}} </pre>

With the "noage=1" option, the month and day can be "1".

===Examples===
If, for example, a reference dated July 4, {{#expr:{{CURRENTYEAR}}-1}} mentions that someone is 50 years old, that person's birth year and age can be rendered using:
 <nowiki>{{birth based on age as of date |50 |</nowiki>{{#expr:{{CURRENTYEAR}}-1}}|July|4}}

{| class="plainlinksneverexpand" style="margin-top:0;"
!style="border:1px solid #aaa;background:#dfd;"|
The following examples are for a person reported as being 50 years old in {{#expr:{{CURRENTYEAR}}-1}}
