I need to calculate total turn around time between a start date and time and an end start and time. The turnaround time would be reported in total hours between the two and need to exclude weekends and holidays.
Example:
Date ReceivedTime ReceivedDate CompletedTime CompletedTurnaround Time in Hours
1/3/238:261/4/238:26
1/3/2313:151/4/2216:33

Please also clarify the cell formats in order for it to work. Thanks,

Okay, the NetWorkDays.INTL function is an inclusive calcuation and not a difference of days. So, it includes the first day in the function So, Tuesday to Wednesday is 2 days, so, I subtracted 1 in the following updated mini worksheet. Toinclude weekends as Fri Sat, Sat instead of doing a enum code you need to use a text string where a 0 counts as a workday and 1 counts as a non workday. So for Fri, Sat, Sun the argument is "0000111".

The only delay is the completion time. We dont want to be negatively affected due to the delay when it is out of our control. We can set them up on the same row if that is easier.

I'm still not sure on what that means regarding a calculation. Does partial mean that you will not start any work until all the information is ready to be processed?

Yes, that is correct so partials will always have an extended turn around time. Which we want to calculate separately so it doesn't skew the normal turn around times. For example, we get in 50 samples but 5 are partials. We enter two rows for that lot. One normal (45 samples) and one partial (5 samples). We want to calculate the normal turnaround time for the ones we can process right away and the partial's turnaround time using the date/time received for all 50 samples, not when we start the partials. Currently there are two separate rows to distinguish the different processing times but if we need to place them on one row with columns to denote the partial info we can.

Any luck on why it is calculating the extra 24 hours with the first formula? I still haven't figured it out.

I think I figured it out. I removed the 24 at the very begining and with the decimal for hours it works now.

What am I doing wrong? Formula is not calculating correctly.

Your image is really tiny. And i can't see your formulas as well, which is what we need to review. Can you post it using the xl2bb add in?
