Calculate fully completed scheduled work hours

[Michael_N]

Hi

I am trying to calculate the number of complete hours staff has worked at different times during the day. It is a 24/7 schedule. 

Below is an example of how the data looks (there are thousands and thousands of rows like this). An Id that represent a staff member, and date/time when they start work and end work. 

I am trying to figure out how to calculate the number of fully completed scheduled working hours that there are at different times during the day, i.e. between  0800 - 0900, 0900 - 1000, 2200 - 2300 (at all hours during the day). I am interested in both fully completed hours but also partly completed hours, i.e. start at 0730...or end at 1615. 

I want to be able to select several days or weeks to see aggregated statistics for scheduled hours at different times during the day.

Right now I am stuck, so any help is appreciated.

This way I can heck if it's within an interval, but it doesn't feel like I am going about it in a QlikView way.
