Hi All,

I need formula for Trun around Time (TAT) For Incident.

For Ex. Start Date Time : 25/2/2018 10:00 AM

End time : 28/2/2018 6:00 PM

Manual TAT calculation is :- 53:00

Working hours for Sat to thu is 7:00 Am to 10 Pm  & For Friday is 9:30 AM to 6:30 PM

So I need the Formula as per the Working hours and all days which calculate TAT.

Hi,

With data structured like this

the formula could be

=NETWORKDAYS.INTL(F2+1,G2-1,"1111011")*9/24 +
  (INT(G2-1)-INT(F2+1)+1-NETWORKDAYS.INTL(F2+1,G2-1,"1111011"))*15/24 +
 (IF(WEEKDAY(F2,2)=5,$C$3,$C$2)-MOD(F2,1) +
 MOD(G2,1)-IF(WEEKDAY(G2,2)=5,$B$3,$B$2))

I added helper cells for working hours, in general could be hardcoded using TIME() function.

Sample is attached.
