Three letter date in System Variable?

re: <$shortmonthname> <$daynum>, <$year>

Because future searches are apt to stumble across this thread, I might add that a very common misperception with date-oriented Variables is due to the Building Blocks elements only being available for System Variables. That BB menu is not present when creating or editing a user Variable.

People do try to type/paste them into user Variable definitions, but they just get rendered as plain text.

The problem is that the System Variables have access to {hidden} operating-system supplied data objects, for which the BBs control the presentation. User Variables are defined only by their Definition dialog field, which is just text, FM special characters, \x or \u codepoints, and any applied Character Format. It might be useful if a Var def could accept expressions, other $Vars, etc., but FM hasn't supported that yet.

<$shortmonthname> ?
