Days between 2 date columns to be calculated but also exclude saturdays and sundays

[mitchpj75]

Requirement - I am trying to calculate the number of days between 2 date columns ('Date of referral' and 'Date of initial attempted contact) , excluding saturday and sunday.  Then convert the total days to hrs as I need to show whether the time between the 2 dates is <= or => 24 hrs.

Method:

1) In Power Query Editor, on table called 'Case atts and case atts values merged', I have a custom column called 'Date of intial attempted contact minus date of referral - KPI 3'. 

The custom query is = [Date of initial attempted contact]-[Date of referral] fields.

This gives me the days between dates.

I also have a date table (called 'Date") which sets out a column called 'IsWorkingDay' showing Saturday and Sunday as False (all other days are True).

How do I use the date table to exlude saturday and sunday from my custom query of [Date of initial attempted contact]-[Date of referral] days between dates??

Really looking for some help as struggling!

Thanks!

Thank you for the response! I did look at these as the solution but I still struggled however through further searching I was able to do what I need with the following:

Watched this first - https://www.youtube.com/watch?v=kRACuS4eKWA

Then used the code here to setup the UI and it worked - https://www.thebiccountant.com/2020/02/20/date-networkdays-function-for-power-query-and-power-bi/

All seems overly complicated to work out the number of working days between dates but the solutions worked.
