Hello everyone,

Context : I am trying to calculate how many days one task, and a whole project (which is a compilation of many tasks) takes to be done. The difficulty here is that I need to exclude in the days the hours that are not worked. We assume that we are working between 9:00 and 19:00, which makes 10 worked hours a day. We also assume that we are not working on Sundays.

Knowing this, I have 3 different columns :

- The first tells the date and hour of the beginning of a task
- The second tells how much total time the task takes to be completed
- The third one is supposed to give me the end date and time of the task when it is completed, knowing all of our assumptions.

So I am trying to build this formula where I could calculate the 3rd column.

Does anybody have an idea ? I tried to look in the forum and I was surprised that this question had never been raised

Thank you very much
