Hey everyone,

I'm trying to calculate the number of business hours between 2 dates + times. I've tried using two formulas and was able to get correct values for entries with the same date, but for lines with different created times and resolved times, I'm getting incorrect values. I could use some help asap.

I have intentionally split the work using lot of intermediate columns so that it will be easy to understand the concept.
Split the work in to 6 steps.
1: calculate number of days between the date created and date resolved. it is in col G
2. Part 0 will only handle the cases when it is created and resolved in the same day. it is in col H. If dt created and dt resolved are same dt, part2, part3, part4 will be always 0.
3. Part2, part3, part4 will deal when dt created and dt resolved are different.
a) part2 is the hours spent between hour created and endofthe day of business.
b) part3 is 11 hrs add for every day the ticket remains not closed.
c) part4 is the hours spent on the last day from businessopening to time resolved.
if you add part0, part1, part2, part3 that will give you tot hours ticket remains opened.

you have to decide about error/overtime. what happens if the ticket created is after businessisclosed for the day. do you give them overtime.
what to do if the ticket is closed at 5am, even though business only opens at 7am.
what to do if ticket resolved time is same date but earlier.
etc.
though it can be done in formula like this, it is a good case to write a vba macro function and you can simply use it like any other excel functions.
If it helps, pl mark it as a solution.
