{{تغییرمسیر۳|noquotes|[[الگو:Birth based on age as of date]]}}&lt;br /&gt;
{{الگوی پیچیده}}&lt;br /&gt;
&lt;br /&gt;
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&amp;#039;s publication. &lt;br /&gt;
&lt;br /&gt;
===Syntax===&lt;br /&gt;
&amp;lt;pre&amp;gt; {{Birth based on age as of date|age |year|month|day}} &amp;lt;/pre&amp;gt;&lt;br /&gt;
The age, year, and day must be supplied as [[عدد طبیعی]]s; month can be specified as a natural number as well as by name or abbreviation (e.g. &amp;quot;August&amp;quot; or &amp;quot;Aug&amp;quot;).  The [[گاه‌شماری میلادی]] is assumed, with no special support provided for [[dual dating]] or the difference between [[Old Style and New Style dates]].&lt;br /&gt;
&lt;br /&gt;
If they are not known, the &amp;quot;day&amp;quot; and &amp;quot;month&amp;quot; fields can be omitted; this is useful if, for example, only the publication year for a source is known.&lt;br /&gt;
&lt;br /&gt;
===Options===&lt;br /&gt;
To suppress the age field:&lt;br /&gt;
&amp;lt;pre&amp;gt; {{Birth based on age as of date|age |year|month|day |noage=1}} &amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
With the &amp;quot;noage=1&amp;quot; option, the month and day can be &amp;quot;1&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
To replace the &amp;#039;/&amp;#039; separator with &amp;#039; or &amp;#039; in compliance with [[IP:APPROXDATE]], add {{پارا|mos|1}}&lt;br /&gt;
:&amp;lt;code&amp;gt;&amp;lt;nowiki&amp;gt;{{Birth based on age as of date|50 |&amp;lt;/nowiki&amp;gt;{{#expr:{{CURRENTYEARL}}-1}}|{{CURRENTMONTHL}}|{{CURRENTDAYL}}|mos=1}}&amp;lt;/code&amp;gt;&lt;br /&gt;
::{{Birth based on age as of date|50 |{{#expr:{{CURRENTYEARL}}-1}}|{{CURRENTMONTHL}}|{{CURRENTDAYL}}|mos=1}}&lt;br /&gt;
===Examples===&lt;br /&gt;
If, for example, a reference dated July 4, {{#expr:{{CURRENTYEARL}}-1}} mentions that someone is 50 years old, that person&amp;#039;s birth year and age can be rendered using:&lt;br /&gt;
 &amp;lt;nowiki&amp;gt;{{Birth based on age as of date|50 |&amp;lt;/nowiki&amp;gt;{{#expr:{{CURRENTYEARL}}-1}}|July|4}}&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;plainlinksneverexpand&amp;quot; style=&amp;quot;margin-top:0;&amp;quot;&lt;br /&gt;
!style=&amp;quot;border:1px solid #a2a9b1;background:#dfd;&amp;quot;|&lt;br /&gt;
The following examples are for a person reported as being 50 years old in {{#expr:{{CURRENTYEARL}}-1}}&lt;br /&gt;
