Hi,

I'm currently on a placement where at the moment I'm trying to figure out a calculation too complex for my understanding.

We need to find a way to calculate the duration in minutes between two dates while considering different operating hours (Standard, 24/7, and 3rd party). Standard hours are 7am - 9pm M-F, 8am - 5pm Sat, and closed on Sunday.
We currently use Excel 2016.

Appreciate any help.

Thanks.

14Calculate Duration between Start and End times
15Hours within Standard Operating Hours is needed, anything out of these hours shall be deducted from overall duration.

17However, for 24/7 operating hours, duration is simply total difference between start and end.
183rd Party Defined operating hours will need to remain as a manual input, so cell should be left blank.

Solution
As addition to previous post:

if duration needs to be in minutes just format cell E2 into a Number format and the formula becomes
Excel Formula: 
=(IF(LEFT(D2,8)= "Standard",((NETWORKDAYS.INTL(B2,C2,"0000011",)-1)*($K$4-$J$4)+IF(NETWORKDAYS.INTL(C2,C2,"0000011",),MEDIAN(MOD(C2,1),$K$4,$J$4),$K$4)-MEDIAN(NETWORKDAYS.INTL(B2,B2,"0000011",)*MOD(B2,1),$K$4,$J$4))+((NETWORKDAYS.INTL(B2,C2,"1111101",)-1)*($K$5-$J$5)+IF(NETWORKDAYS.INTL(C2,C2,"1111101",),MEDIAN(MOD(C2,1),$K$5,$J$5),$K$5)-MEDIAN(NETWORKDAYS.INTL(B2,B2,"1111101",)*MOD(B2,1),$K$5,$J$5)),C2-B2))*1440

Hi,

That worked exactly as needed. Thank you for you help, I appreciate it!

As a secondary, would there be any way of adding bank holidays in to the mix so that the hours in those days are not calculated either?

Yes, create a range somewhere on your sheet with dates and insert them into the formula. Never mind the way they're sorted, that has no bearing for the working of the formula.
I assume you want to bank holidays deducted from 24/7 as well. If Yes, change to this:

Apologies, should've been more specific. Bank holidays only need to be deducted from the standard and 3rd Party Operating hours, the 24/7 OH's are for internet facing services etc. so will be calculated 24/7 no matter what.
