So I have a start and an end date and I need to calculate turnaround time in working days.
Excel has NETWORKDAYS which does the removing of weekends all by itself.
Is there an equivalent for M-Code? I have googled and can only find complex code to work out days, weeks, weekends etc and subtracting these.
Thanks!

Solved! Go to Solution.
You would invoke it in your original table as Add Columns->Invoke Custom Function. Set each argument as column and use your start date column and end date column.
Edit: Or alternately use it in Advanced Editor, and pass on Start & End as variable (from calculation, another query etc).
Oh, custom function should be copied and pasted into new blank query (using advanced editor). Name it something that makes sense. (Ex: fnWorkday).
No built-in "M" function to do it. You can create custom function like below.
Ex: Week starting Monday, Sat & Sun as weekend.
(sDate as date, eDate as date)=> let vDur = Duration.Days(Duration.From(eDate - sDate)), Source = List.Dates(sDate, vDur + 1, #duration(1, 0, 0, 0)), #"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error), #"Added Custom" = Table.AddColumn(#"Converted to Table", "Weekday", each Date.DayOfWeek([Column1],Day.Monday)), #"Filtered Rows" = Table.SelectRows(#"Added Custom", each ([Weekday] <> 5 and [Weekday] <> 6)), Row_Count = Table.RowCount(#"Filtered Rows") in Row_Count
Edit: There are other ways to write custom function (such as using List.Generate/List.Accumulate), but above should be easier to maintain/change if you needed to.
Thanks! I suspect this is something I'm expected to do in DAX but I can think in M, DAX gives me headaches 🙂
Hello again Chihiro,
Where should I insert your formula? Into a new custom column within Query Editor?
I am trying to avoid the creation of a new table with a row of dates - it seems a fairly inefficient way of doing something so I don't mind a function even if it is complex if it does the job in one column or measure!

Could you not create a custom dates table and denote when a date is a weekend and when it is a weekday?
