Networkdays with start and end times on different days due to multi country shifts

[SteelBird]

Hi,






I am faced with this scenario where I need to calculate the number of minutes between two date & time stamps with the Start and End time in different hours . My scenario is as below


Excluding Hours between 7:00 PM to 11:00 PM EST all other time, excluding Saturday and Sunday and Holidays need to be calculated


I am currently using this formula, but it yields incorrect results due to the the start and end times spanning multiple days




=IF(U3="Y",,((NETWORKDAYS.INTL(Q3,R3,1,HolidayRef!$A$1:$A$2)-1)*(TimeRef!$A$2-TimeRef!$B$2)+IF(NETWORKDAYS.INTL(R3,R3,1,HolidayRef!$A$1:$A$2),MEDIAN(MOD(R3,1),TimeRef!$A$2,TimeRef!$B$2),TimeRef!$A$2)-MEDIAN(NETWORKDAYS.INTL(Q3,Q3,1,HolidayRef!$A$1:$A$2)*MOD(Q3,1),TimeRef!$A$2,TimeRef!$B$2))*24*60)


Where Y is an internal control variable and my TimeRef sheet has Start Time as 23:01 and End time as ​19:00


I get incorrect results when the time stamps are in the same day or the next day. Some examples are below




Start Date End Date ElapsedTime
5/31/2019 8:42 5/31/2019 9:49 0.00
5/31/2019 9:49 6/6/2019 9:35 -964.00​


Any help would be greatly appreciated!
