my purpose is to see , Month by Week Number as per above , instead the Week count from Jan to Dec , 

and below is the Dimdate i use. Kindly assist me how to generate this ? 

 

let fnDateTable = (StartDate as date, EndDate as date, FYStartMonth as number) as table =>

  let

    DayCount = Duration.Days(Duration.From(EndDate - StartDate)),

    Source = List.Dates(StartDate,DayCount,#duration(1,0,0,0)),

    TableFromList = Table.FromList(Source, Splitter.SplitByNothing()),  

    ChangedType = Table.TransformColumnTypes(TableFromList,{{"Column1", type date}}),

    RenamedColumns = Table.RenameColumns(ChangedType,{{"Column1", "Date"}}),

    InsertYear = Table.AddColumn(RenamedColumns, "Year", each Date.Year([Date]),type text),

    InsertYearNumber = Table.AddColumn(RenamedColumns, "YearNumber", each Date.Year([Date])),

    InsertQuarter = Table.AddColumn(InsertYear, "QuarterOfYear", each Date.QuarterOfYear([Date])),

    InsertMonth = Table.AddColumn(InsertQuarter, "MonthOfYear", each Date.Month([Date]), type text),

    InsertDay = Table.AddColumn(InsertMonth, "DayOfMonth", each Date.Day([Date])),

    InsertDayInt = Table.AddColumn(InsertDay, "DateInt", each [Year] * 10000 + [MonthOfYear] * 100 + [DayOfMonth]),

    InsertMonthName = Table.AddColumn(InsertDayInt, "MonthName", each Date.ToText([Date], "MMMM"), type text),

    InsertCalendarMonth = Table.AddColumn(InsertMonthName, "MonthInCalendar", each (try(Text.Range([MonthName],0,3)) otherwise [MonthName]) & " " & Number.ToText([Year])),

    InsertCalendarQtr = Table.AddColumn(InsertCalendarMonth, "QuarterInCalendar", each "Q" & Number.ToText([QuarterOfYear]) & " " & Number.ToText([Year])),

    InsertDayWeek = Table.AddColumn(InsertCalendarQtr, "DayInWeek", each Date.DayOfWeek([Date])),

    InsertDayName = Table.AddColumn(InsertDayWeek, "DayOfWeekName", each Date.ToText([Date], "dddd"), type text),

    InsertWeekEnding = Table.AddColumn(InsertDayName, "WeekEnding", each Date.EndOfWeek([Date]), type date),

    InsertWeekNumber= Table.AddColumn(InsertWeekEnding, "Week Number", each Date.WeekOfYear([Date])),

    InsertMonthnYear = Table.AddColumn(InsertWeekNumber,"MonthnYear", each [Year] * 10000 + [MonthOfYear] * 100),

    InsertQuarternYear = Table.AddColumn(InsertMonthnYear,"QuarternYear", each [Year] * 10000 + [QuarterOfYear] * 100),

    ChangedType1 = Table.TransformColumnTypes(InsertQuarternYear,{{"QuarternYear", Int64.Type},{"Week Number", Int64.Type},{"Year", type text},{"MonthnYear", Int64.Type}, {"DateInt", Int64.Type}, {"DayOfMonth", Int64.Type}, {"MonthOfYear", Int64.Type}, {"QuarterOfYear", Int64.Type}, {"MonthInCalendar", type text}, {"QuarterInCalendar", type text}, {"DayInWeek", Int64.Type}}),

    InsertShortYear = Table.AddColumn(ChangedType1, "ShortYear", each Text.End(Text.From([Year]), 2), type text),

    AddFY = Table.AddColumn(InsertShortYear, "FY", each "FY"&(if [MonthOfYear]>=FYStartMonth then Text.From(Number.From([ShortYear])+1) else [ShortYear]))

Re: How to calculate week number ( 1,2,3,4, ) by Month

Hi there. Are you looking for "Date.WeekOfMonth([DateColumn])"? edit query has this option on the buttons of the transform and add column tab.
