Hello all. I am a novice Excel user, and cannot seem to locate the
source of my problem. Please help!


Here is my sheet:


C4 D4
E4 F4 G4 H4

9/22/2005 7:10 PM___10/1/2005 12:13 PM___ 8.7__52.6__6.0__317.64

Start date is entered into C4.
End date is entered into D4.

The following formula is in E4 to determine elapsed days:

=IF(D4=0,"",IF(C4=0,"",(IF(ISERROR((D4-C4)*24),"",(D4-C4)*24)/24)))

F4 contains "FLAGED HOURS" (for a body shop estimate)

G4 contains a value used for "cycle time" and is using the following
formula:

=IF(F4=0,"",F4/E4)

H4 contains a simple multiplication formula: =(F4*G4), but returns
317.64 INSTEAD of 315.6 (which is 52.6 x 6.0). I need the 315.6 result
in H4.

Would someone please tell me what I am doing wrong????

Thanks very much!

The cells contain trailing digits which you are not seeing.

You could try

=(ROUND(F4,2)*(ROUND(G4,1)))

This appears to be a rounding problem....Try changing the foemula in H:4
to =F4*ROUND(G4,0)

Well, I need more help on these sheets. I've made two attachments (I
wish I could figure out how to imbed an image directly into the message
here...)

On sheet 1, this is the code to figure the required date for a cycle
time. This is from column F-

=IF(C3=0,"",C3+(D3/E3))


This is the code from column G, that tells me how many days between C
and F-

=IF(F3=0,"",IF(C3=0,"",(IF(ISERROR((F3-C3)*24),"",(F3-C3)*24)/24)))

I need the formula to exclude Saturdays and Sundays. Is this possible?
If possible, it would be great to have it display " x days x hours"
instead of "5.8" days.

On sheet 3, I am using the same code-

=IF(D3=0,"",IF(C3=0,"",(IF(ISERROR((D3-C3)*24),"",(D3-C3)*24)/24)))

...to tell me how many elapsed days between C and D, and still need the
same fix, as above.

Please help!

Try using Excel formula: =networkdays(start date,end date). You can even
exclude holidays using this formula. First, though, you have to go to Tools,
Add-Ins... and select the Analysis ToolPak. Takes about two seconds to do.
The Analysis ToolPak give you a choice of lots more formulas.

I've tried incorporating the NETWORKDAYS function into the current
formulas, but can't get it to work. Playing with NETWORKDAYS on a
blank sheet, it rounds to the day. I need results to the hour. Any
further help, or examples using my formulas?

Thanks!

Terry

Can I confirm what you want to do?

Do you want to calculate the number of days and hours between two
date/times (excluding weekends) or do you want to generate a date/time
based on a number of days (possibly fractional) added to a start
date/time? (or both :) )

If the latter then how many hours constitute a day? If you add 1.2 days
to 18:00 on a Monday what should the result be? Do you want the time
returned to be any time of the day or should it be within specific
hours, e.g. your working hours, if so what are these?

Looking at your sheet1 looks like you want to add the number of days in
G3 (5.8) to the date in C3, excluding weekends, If any time on a
working day is acceptable perhaps

=WORKDAY(C3,G3+MOD(C3,1))+MOD(C3+G3,1)

although, depending on your answers to my questions above, you might
need a more complex formula.....

Thanks for the help so far guys... I am by no means an expert at Excel,
and am only trying to help a friend who owns a body shop. Believe me,
he is not guru at computers, but can bring a car back to life Chris
Foose.

Basically, Progressive Insurance requires that their jobs be completed
within a certain "cycle time", based on when the car arrives at the
shop and when the repairs are completed. A cycle time of 4.0 or 4.5 is
acceptable, but anything below that, and Progressive starts to limit the
number of vehicles that are brought to my friends shop for repairs. His
business is new, and I am doing all that I can to help him get started.

I created one sheet where you input a start date and time and an end
date and time. This sheet calculates the cycle time based on "flag
hours (the number of hours Progressive estimates that the repairs will
take)".

I created another sheet where you input a start date and time, desired
cycle time, and it will tell you when the vehicle is due to maintain
the cycle time that you input in the cell.

What I need is to exclude weekend days, and the work hours for the week
can include all 24 hours of each day. I only need to exclude weekend
days if they fall into the date ranges that are manually added.

I did find this VB code on the net, but I have no idea how to use it:

'**************************************

checkAvailableDays = dayscalculation(CalculationStartDate,

'---Amazing this code actially works


Private Function dayscalculation(CalculationStartDate As Date,
WPAEmpEndDate As Date)
Dim workingdays As Integer
StDateValue = CDate(CalculationStartDate)
EndDateValue = CDate(WPAEmpEndDate)
If (StDateValue EndDateValue) Then
MsgBox "Sorry Invalid Date Value", vbCritical, "VOID"
workingdays = 0
Else
If (StDateValue = EndDateValue) Then
MsgBox "Sorry Dates are Same", vbCritical, "VOID"
workingdays = 0
Else
workingdays = DateDiffW(StDateValue, EndDateValue)
End If
End If
dayscalculation = workingdays
End Function


Private Function DateDiffW(StDateValue, EndDateValue)
For i = StDateValue To EndDateValue
If (Weekday(i) < 1) And (Weekday(i) < 7) Then
WorkingDaysValue = WorkingDaysValue + 1
End If
Next
DateDiffW = WorkingDaysValue
End Function

If you guys are will to help, I can email my small Excel files to you
for your expert diagnosis :)
