DATEDIFF(d, myorderdate, sentdate) -2*DATEDIFF(weeked, myorderdate, sentdate) as Totalday is the answer. It works for me. Please refund

Use this function to get the date difference, excluding Weekends (Saturday & sunday)

Function DiffWeekdays(ByVal datDay1 As Date, ByVal datDay2 As Date) As Long
' Comments  : Returns the number of weekdays between two dates
'             The days are rounded down -- it takes 24 hours to make a day.
' Parameters: datDay1 - first (earlier) date/time (subtracted from datDay2)
'             datDay2 - second (later) date/time
' Returns   : Number of whole business days between two dates
'             (Returns negative days if datDay1 is after datDay2)
'
Dim lngDays As Long
Dim lngWeeks As Long
Dim datFirstDate As Date
Dim datLastDate As Date
Dim datNewDate As Date
Dim intDirection As Integer

If datDay1 < datDay2 Then
datFirstDate = datDay1
datLastDate = datDay2
intDirection = 1
Else
datFirstDate = datDay2
datLastDate = datDay1
intDirection = -1
End If

' Subtract weekends
lngWeeks = ((Convert.ToInt32(datLastDate.DayOfWeek) - Convert.ToInt32(datFirstDate.DayOfWeek)) / 7)
lngDays = lngWeeks * 5
datNewDate = DateAdd(DateInterval.Day, (lngWeeks * 7), datFirstDate)
While datNewDate < datLastDate
If datNewDate <= datLastDate Then
' Don't count days when new day is Sunday or Saturday.
' (When new day is Saturday, you are actually counting Friday)
If Weekday(datNewDate) <> 1 And Weekday(datNewDate) <> 7 Then
lngDays = lngDays + 1
MsgBox(Weekday(datNewDate) & " " & lngDays)
End If
End If
End While
DiffWeekdays = intDirection * lngDays
End Function
