Sum of only monthly hours

Hi,

I need formula help in attached report.

I wanted formula in "Total Hours" column (row B6 & C6) which sum the weekly hours for that month from the "Hours" column (row B3 to D3).

The issue is that if week end in next month then formula should divide the hours as per the days in that month.

In attached report last week ended in 03rd Aug so in July month I need total for 20 + 30 + 24 ( last 3 days of July) and remaining 16 hours in the month of Aug.

Assumption: Daily 8 hours and week Monday - Friday.

Thanks,
Rahul
