Working Days

[ArchStanton]

I have a Working Days column that produces True / False in my Calendar that works perfectly fine:

Working Days = NOT WEEKDAY('Date'[Date]) IN {1,7}

I would like to incorporate my Public Holidays calendar to the column.

I have tried adding RELATED (see below) but that doesn't work

Working Days = NOT WEEKDAY('Date'[Date]) IN {1,7} &&
RELATED('bank-holidays'[Public Holiday])

Does anyone know how to combine them?

Thanks

@ArchStanton,

Try this calculated column in your Date table. It requires a 1:* relationship between Date and bank-holidays.

Working Days = 
NOT WEEKDAY ( 'Date'[Date] ) IN { 1, 7 } && ISBLANK ( COUNTROWS ( RELATEDTABLE( 'bank-holidays' ) ) )

Can you briefly explain how this works please?

My understanding is that NOT produces a list of FALSE values if the Date is a Weekend (not a work day), then this list is used as Lookup to the Bank Hoilday table where all NONBLANKS (public holidays) are also counted as FALSE - the 2 are then combined.

Is that correct - does it make sense?

@ArchStanton,

The two expressions are evaluated independently. The first one works as described (check if Date is a weekend). The second one checks if the date in the current row of the Date table exists in bank-holidays table; if it doesn't, then it's considered a working day (assuming it's not a weekend). The assumption is that bank-holidays contains only holidays. Hope that helps.
