CRM Email - Format Date "MM DD, YYYY"

We are on CRM 2016 v8.1 and I am trying to add the long date to an email (not template) but it doesn't seem to be a way to do this.  If there is, could you please share.

I am interested to know where the long date can be used in CRM as I can't recall ever seeing it anywhere with any of the organizations I've worked with, nor do I know how to use it.  I've also seen posts on using /@date or /@time but this just extracts the dateparts.  Can anyone tell me how/where to use the long date?

Any thoughts on this is much appreciated.

Thanks,
Chrys
