Manipulate Date in SQL Statement

Hello Experts,

I have a SQL table that keeps information about monthly Transactions by Day of Week as opposed to actual date. Below is an example:

Month              DOW
01-Jan-2014     Mon
01-Jan-2014     Tue
01-Jan-2014     ----
01-Jan-2014     Sun
----
01-Feb-2014     Mon
01-Feb-2014     Tue
---
01-Dec-2014     Mon
01-Dec-2014     Tue
---
01-Dec-2014     Sat
01-Dec-2014     Sun

As you can see, the day of month in the Month column is always 01.

I need to add a 3rd column for a new Date value that is dependent on the value of both Month and DOW columns. Basically, I need to convert day value from the generic 01 value to a value between 1-7:
01-MMM-YYY
02-MMM-YYY
03-MMM-YYY
04-MMM-YYY
05-MMM-YYY
06-MMM-YYY
07-MMM-YYY

The new date will be determined according to the Month and DOW values, so for example:


Month              DOW          New Date        
01-Jan-2014     Mon          06-Jan-2014
01-Jan-2014     Tue          07-Jan-2014
01-Jan-2014     Sun          05-Jan-2014
01-Feb-2014    Mon         03-Feb-2014
01-Feb-2014    Tue          04-Feb-2014
01-Dec-2014    Mon         01-Dec-2014
01-Dec-2014    Tue          02-Dec-2014

Ideally, the new column should be added to the Select statement as condition or CASE statement, based on the values in Month and DOW.

Many thanks in advance.
