Rolling average working days lost using start and end date

I'm trying to work out the average working days lost for the business by day. The calculation that we use is to divide the total number of days absence over the previous year by the average full time eqivalent number of staff. We would need to see this figure for the last 12 months, meaning we'd need 2 years worth of data.

 

The absence report is set up to include a row for each absence, regardless of length. Each person will have a start and end date, and its this that we would use to determine whether a person has been off on a particular day, or not. 

 

The source of our data doesn't allow us to connect directly (i.e using a data warehouse), so we would have to export into Excel Power Query to manipulate it, before uploading to PowerBI. 

 

Any ideas?
