When you have a range statement you save two characters (e.g. Mo-Fr
becomes M-F) and I simply made mention of that because that was the
topic of the thread at this point, range statements.

I can understand the problem with Saturday and Sunday.  The abbreviation
of Thursday to R happens in many business settings (usually in highly
compressed tables) and the work world obviously revolves around M-F
leaving Saturday and Sunday out.
