Calculate Business Days

NETWORKDAYS function (DAX) - DAX | Microsoft Learn

Hi roscas ,

If you want to mark up Business Days in PowerQuery, please refer to the steps below:

let
    Source = List.Transform({Number.From(#date(2024,1,1)) .. Number.From(#date(2024,12,31))},Date.From),
    #"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), {"Date"}, null, ExtraValues.Error),
    #"Changed Type" = Table.TransformColumnTypes(#"Converted to Table",{{"Date", type date}}),
    ListOfWeekDays = List.Select(#"Changed Type"[Date], each List.Contains({0,1,2,3,4},Date.DayOfWeek(_, Day.Monday))),
    Holidays = { #date(2024,1,1), #date(2024, 12, 25) },
    ListOfWorkDays = List.Select(List.Difference(ListOfWeekDays, Holidays ?? {}),each _ >= Inicio{0} and _ <= End{0}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Business Days", each if List.Contains(ListOfWorkDays,[Date]) then "xxx" else null)
in
    #"Added Custom"

If you want to count Business Days, then undoubtedly Ibendlin's method is the most recommended.
