Should hopefully be a very quick one here for one of you super clever dudes!

Is there a calculation that will give the total number of week days (excluding weekends within a given period?

If ( Date1 and Date2 ) ;

Let ( [

spanStart = Date1 - Mod ( Date1 ; 7 ) ;

spanEnd = Date2 - Mod ( Date2 ; 7 ) + 6 ;

wkndCount = Div ( spanEnd - spanStart + 1 ; 7 ) * 2 - (spanStart < Date1 ) - ( spanEnd > Date2 )

] ;

Date2 - Date1 + 1 - wkndCount

)

)

Indeed, but Michael's CF is slightly more flexible:

If you put ValueCount( around it.... it could then be made to deal with regular days off as well!

--sd

Tried your calculation replacing date1 and date2 in your calculation with the 'from' and 'to' dates in my database but the first line is coming up with the 'There are too few parameters in this function' message!

Did you call it this way:

ValueCount(WeekDaysInRange ( FromDate ; ToDate ; "1¶7" ))

:

--sd

If ( Date1 and Date2 [color:red]) ;

Remove the bracket in red.

Soren, I agree Michael's is more flexIble than mine.

I don't think you need to use a recursive calculation for this. If you want the flexibility of being able to select which days are considered weekends, see here:

Even better!

Thanks for everyone's help on this. :beertime
