Don't know about speed, but there's already a DOW routine built into the
calculator, the TSTR function wouldn't be able to do what it does...  So why
don't we use it:

<< 12.00 TSTR 1 3 SUB >>

If you want the number too:

<< 12.00 TSTR 1 3 SUB
   DUP {"SUN" "MON" "TUE" "WED" "THU" "FRI" "SAT"} POS 1 - >>

Date is in DD.MMYYYY format.
