NETWORKDAYS dynamically filtering by dates and person

[Albatross810]

I want to calculate the working days between dates with varying holidays within a specified period. For example, I have a table that lists personal holidays:

Person	Holidays
Jane	02-Feb-23
Jane	03-Mar-23
Jane	21-Jul-23
Michael	01-Mar-23

And I have a table with jobs

Jobs
Job	Person	Start	End	Availability
Job 1	Jane	01-Jan	04-Feb	(Working days - holidays)
Job 2	Michael	10-Feb	21-Apr

I need the Availability column to include working days between those dates (or dates i select from a slicer, for example all of February), removing dates from the other table where the person has a holiday. Can anyone help me find a solution for this please?

@Albatross810 New way: NETWORKDAYS function (DAX) - DAX | Microsoft Learn

Old way: Net Work Days - Microsoft Power BI Community

Been working with NETWORKDAYS all day, can't seem to solve this one. It doesn't sum multiple periods if I'm selecting several for example and won't let me use the holiday table dynamically by owner. But thank you for sharing.

@Albatross810 So like this?

Measure = 
    VAR __Person = MAX('Jobs'[Person])
    VAR __Result = NETWORKDAYS(MAX([Start]), MAX([End]), 1, SELECTCOLUMNS(FILTER('Holidays', [Person] = __Person),"__Holidays",[Holidays]))
RETURN
    __Result

Thanks so much, this worked well!
