Counting Consecutive Monday to Friday as a Group

[Stephen_IV]

In A1 I have a start Date 7/22/2011 and in B1 I have an end date 7/29/2011. What I am trying to do is to count how may Monday to Friday consecutive groups there are in that date range. For example 7/22/2011 is a Friday, 7/23/2011 is a Sat, 7/24/2011 is a Sunday, 7/25/2011 is a Monday, 7/26/2011 is a Tuesday, 7/27/2011 is a Wednesday, 7/28/2011 is a Thursday,and 7/29/2011 is a Friday. The count for this range would be 1 because 7/22/2011 is Friday and 7/26/ is Monday. Tried to modify this formula but to no avail
=SUMPRODUCT(--(MOD(WEEKDAY(ROW(INDIRECT(A6&":"&B6)),2),4)=1)). Thanks in advance.

Corrected formula...

<br /><table cellpadding="2.5px" rules="all" style=";background-color: #FFFFFF;border: 1px solid;border-collapse: collapse; border-color: #A6AAB6"><colgroup><col width="25px" style="background-color: #E0E0F0" /><col /><col /><col /></colgroup><thead><tr style=" background-color: #E0E0F0;text-align: center;color: #161120"><th></th><th>A</th><th>B</th><th>C</th></tr></thead><tbody><tr ><td style="color: #161120;text-align: center;">1</td><td style="text-align: right;;">Friday, July 22, 2011</td><td style="text-align: right;;">Friday, July 29, 2011</td><td style="text-align: right;;">1</td></tr></tbody></table><br /><br /><table cellpadding="2.5px" rules="all" style=";border: 2px solid black;border-collapse:collapse;padding: 0.4em;background-color: #FFFFFF" ><tr><td style="padding:6px" ><b>Worksheet Formulas</b><table cellpadding="2.5px" width="100%" rules="all" style="border: 1px solid;text-align:center;background-color: #FFFFFF;border-collapse: collapse; border-color: #A6AAB6"><thead><tr style=" background-color: #E0E0F0;color: #161120"><th width="10px">Cell</th><th style="text-align:left;padding-left:5px;">Formula</th></tr></thead><tbody><tr><th width="10px" style=" background-color: #E0E0F0;color: #161120">C1</th><td style="text-align:left">=INT(<font color="Blue">NETWORKDAYS(<font color="Red">A1+CHOOSE(<font color="Green">WEEKDAY(<font color="Purple">A1</font>),1,0,6,5,4,3,2</font>),B1</font>)/5</font>)</td></tr></tbody></table></td></tr></table><br />

You could also try this formula

=INT((WEEKDAY(A1-2)+B1-A1-4)/7)
