Column to set a value if date is between two dates with M language?

[Anonymous]

I have a Sub Date column that simply has dates: 1/1/2020, 1/16/2020, etc. I want to add a custom column in the query that checks IF the date is between first of the month to the 8th of the month, and if so, set value to either TRUE or 1 to signify it's within that date range

How can I achieve this in M?

Hi, @Anonymous 

Based on your description, I created data to reproduce your scenario. The pbix file is attached in the end.

Table:

You may add a custom column with the following m codes.

=if Date.Day([Sub Date])>=1 and Date.Day([Sub Date])<=8 
then 1 else 0

Result:

Hello @Anonymous ,

Please find the steps to achieve the result in query editor.

let
Source = Excel.Workbook(File.Contents("C:\Users\kgawale\Documents\Test 15 March 2021.xlsx"), null, true),
Sheet7_Sheet = Source{[Item="Sheet7",Kind="Sheet"]}[Data],
#"Promoted Headers" = Table.PromoteHeaders(Sheet7_Sheet, [PromoteAllScalars=true]),
#"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"Contract Date", type date}}),
#"Inserted Month" = Table.AddColumn(#"Changed Type", "Month", each Date.Month([Contract Date]), Int64.Type),
#"Added Conditional Column" = Table.AddColumn(#"Inserted Month", "Custom.1", each if [Month] <= 8 then 1 else 0)
in
