    SQL> select 20/03/2006 - 21/03/2006 from dual;

    20/03/2006-21/03/2006
    ---------------------
    -.00016617

    Subtract dates

    That's because you didn't subtract 2 dates, you just subtracted 2 numbers. You need to use date formats:

    Code:
      1* select to_date('25-MAY-2006','DD-MON-YYYY') - to_date('23-MAY-2006','DD-MON-YYYY') from dual
    SQL> /
    
    TO_DATE('25-MAY-2006','DD-MON-YYYY')-TO_DATE('23-MAY-2006','DD-MON-YYYY')
    -------------------------------------------------------------------------
                                                                            2
