[ivandgreat]

Hello,

Im just having a hard time how to come up the results.

I have column date, i wanted to check if it falls from date range 26th from previous  month until 25th of the current month.

Date	Expected Month Output
1/26/2022	Jan
2/5/2022	Jan
2/4/2022	Jan
2/25/2022	Jan
2/27/2022	Feb
3/25/2022	Feb

Thanks in advance.

Hi @ivandgreat ,

• Method1: Add a column in Power Query:

[ 
d=Date.Day([Date]),
f=if d>=26 then [Date] else Date.AddMonths([Date],-1),
m=Text.Start(Date.MonthName(f),3)
][m]

• Method2: Add a column using DAX:

Month = 
var _m=IF(DAY([Date])>=26, MONTH([Date]), MONTH([Date])-1)
return FORMAT( CONVERT(_m &"/1",DATETIME),"mmm")

Hi @ivandgreat ,

I am unsure if you mean the current month is Jun (i.e. now?) or the range at each row.

Below solution applied the conditional formula to replicate the column "Expected Month Output"

if it is what you're looking for, please add a custom column and add formula below:

if ([Date]>Date.AddMonths(#date(Date.Year([Date]),Date.Month([Date]),25),-1)) and ([Date]<#date(Date.Year([Date]),Date.Month([Date]),26)) then Date.ToText(Date.AddMonths([Date],-1),"MMM") else Date.ToText([Date],"MMM")

Let me know if this is what you're looking for.

Regards

Use this formula in a custom column

= Date.ToText(Date.AddDays([Date],-25),"MMM")

See the working here - Open a blank query - Home - Advanced Editor - Remove everything from there and paste the below code to test

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMtQ3MtU3MjAyUorVAfPMEDwjfVNkjgkyxwhFClWXkTmCZ4yi0hihMhYA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}}),
    #"Added Custom1" = Table.AddColumn(#"Changed Type", "Month", each Date.ToText(Date.AddDays([Date],-25),"MMM"), type text)
in
    #"Added Custom1"
