I would like to say a day which meet the following criteria for each month:

• First whole week
• First business day

For example, the day in Dec 2016 is 5, in Jan 2017 is 3 (assume 2 Jan 2017 is holiday).

Currently I only can think of "First business day of first week in each month", but it's sound little bit clumsy and cannot point out the first whole week.

Is there have any better to present this "day"?

Thanks
