Template:Months before now underscore

{{documentation|content= Usage: {{Months before now|how many months}}

E.G. {{Months before now underscore|3}}
 * {{Months before now underscore|3}}

{{Months before now underscore|48}}
 * {{Months before now underscore|48}}

It will not take negative numbers (yet), use {{Tl|Months from now}} instead.
