Calculating response time including weekends? Use network days?

[stephenohear]

Hi good folks. Greetings from Scotland.
I have a question regarding network days, I've searched the forum but cant find an answer that is looks right.
In the table below I'm trying to calculate the response between the 2 times below, based on a working day of 08:00 to 18:00, and should include weekends.
So as below, call is logged on Friday 5th at 08:50am (cell A1) and closed on the Tuesday at 13:50pm (cell B1).
I'm using excel 2016.
Any assistance would be most appreciated.
Thanks.

What do you want the answer to be:

2 days, 4 hours

Or 24 hours

Or 4 days, 4 hours

Or 44 hours?

Ha! Or none of those!! (Replace the 4hrs with 5hrs)

Hi thanks for the reply. I'm looking for the answer to be in Hh:mm format.
I mooched around the forums and found one that would calculate in hours and minutes based on working 8am to 18.00pm Monday to Friday, so basically, i'm looking for the same that would be Monday to Sunday inclusive.
Formula is below, were B2 is time of logging, and J2 is time of closing. I've formatted the target cell to be time > English (US) > 13:30

=(NETWORKDAYS(B2,J2)-1)*("18:00"-"8:00")+IF(NETWORKDAYS(J2,J2),MEDIAN(MOD(J2,1),"18:00","8:00"),"18:00")-MEDIAN(NETWORKDAYS(B2,B2)*MOD(B2,1),"18:00","8:00")

Anyone have any ideas to solve this?

NETWORKDAYS is the number of (normal) working days between 2 dates.

DAYS is the number of days between 2 dates. i.e. If the formula that you posted above works except for weekends then replace NETWORKDAYS with DAYS.

(Have not tested it)

Tried it this morning and got the dreaded #########
original was:
=(NETWORKDAYS(B2,J2)-1)*("18:00"-"8:00")+IF(NETWORKDAYS(J2,J2),MEDIAN(MOD(J2,1),"18:00","8:00"),"18:00")-MEDIAN(NETWORKDAYS(B2,B2)*MOD(B2,1),"18:00","8:00")

Changed to:
=(DAYS(B2,J2)-1)*("18:00"-"8:00")+IF(DAYS(J2,J2),MEDIAN(MOD(J2,1),"18:00","8:00"),"18:00")-MEDIAN(DAYS(B2,B2)*MOD(B2,1),"18:00","8:00")
but its fell over.
Is it anything to do with the median do you think?

Sorry, forgot that DAYS is the other way round. NETWORKDAYS is start date, end date

DAYS is end date, start date.
