No.f days between dates, no w/e and Fridays

[Ricoy-Chicago]

In have been using this formula to find the number of days between two dates,
not including weekends.
txtNoOfDays = DateDiff("d", Date2, Date1) - (DateDiff("ww", Date2, Date1, 7)
+ DateDiff("ww", Date2, Date1, 1)) + 1

It works great, but now I need help with one that does not include Fridays.
I need only the number of days in a month from Mon - Thurs.

Thanks for your help.

Have you tried subtracting (DateDiff("ww", Date2, Date1, 6)?

Oops: unbalanced parentheses!

DateDiff("ww", Date2, Date1, 6)
