Exclude Holiday in existing Networkday code

Hi all

 

I have a code where I exclude the weekends to get the networkdays. Can someone help me to additional exclude the holidays which I want to set up in an excel file?

 

This is my existing code

 

(StartDate as date, EndDate as date) as number =>
let
ListDates = List.Dates(StartDate, Number.From(EndDate-StartDate), #duration(1, 0, 0, 0)),
RemoveWeekends = List.Select(ListDates, each Date.DayOfWeek(_, Day.Monday) < 5),
CountDays = List.Count(RemoveWeekends)
in
CountDays

 

Thanks a lot!

(StartDate as date, EndDate as date) as number =>
List.Count(List.Select(List.Dates(StartDate, Number.From(EndDate-StartDate) + 1, #duration(1, 0, 0, 0)), each Date.DayOfWeek(_, Day.Monday) < 5 or not List.Contains(Holidays, _)))

Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension!

DAX is simple, but NOT EASY!

I don't really know how I should put this in my existing code... Could you write it with my existing code

Thanks a lot! Any idea why the data load takes such a long time? is running for 10min and still didn't load the data...And I only have 3 dates to test in the holiday file.

Hi @jij19,

I'd like to suggest you add buffer functions to these processes to prevent memory leaks and duplicated memory resources spent on these calculations.
