Editing Template:Birth based on age as of date/doc (section)

== Examples ==
If, for example, a reference dated July 4, {{#expr:{{CURRENTYEAR}}-2}} mentions that someone is 50 years old, that person's birth year and age can be rendered using:
<div style="margin-left:1.6em;"><code><nowiki>{{birth based on age as of date|50|</nowiki>{{#expr:{{CURRENTYEAR}}-2}}|July|4}}</code></div>

{| 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}}
