Need help in date table creation

Hi Navaneetharaju_ 

Here is a MQuery I use to create a date table. It shows the last 5 years and next 6 years automatically, you can adapt this for your needs. It also has the last day of the month amongst other columns

let
  // configurations start
  Today = Date.From(DateTime.LocalNow()),
  // today's date
  FromYear = Date.Year(DateTime.LocalNow()) -5,
  // set the start year of the date dimension. dates start from 1st of January of this year
  ToYear = Date.Year(DateTime.LocalNow()) +6,
  // set the end year of the date dimension. dates end at 31st of December of this year
  StartofFiscalYear = 7,
  // set the month number that is start of the financial year. example; if fiscal year start is July, value is 7
  firstDayofWeek = Day.Monday,
  // set the week's start day, values: Day.Monday, Day, Sunday....
  // configuration end
  FromDate = #date(FromYear,1,1),
  ToDate = #date(ToYear,12,31),
  Source = List.Dates(
        FromDate,
        Duration.Days(ToDate-FromDate)+1,
        #duration(1,0,0,0)
    ),
  #"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
  #"Renamed Columns" = Table.RenameColumns(#"Converted to Table", {{"Column1", "Date"}}),
  #"Changed Type" = Table.TransformColumnTypes(#"Renamed Columns", {{"Date", type date}}),
  #"Inserted Year" = Table.AddColumn(#"Changed Type", "Year", each Date.Year([Date]), Int64.Type),
  #"Inserted Start of Year" = Table.AddColumn(#"Inserted Year", "Start of Year", each Date.StartOfYear([Date]), type date),
  #"Inserted End of Year" = Table.AddColumn(#"Inserted Start of Year", "End of Year", each Date.EndOfYear([Date]), type date),
  #"Inserted Month" = Table.AddColumn(#"Inserted End of Year", "Month", each Date.Month([Date]), Int64.Type),
  #"Inserted Start of Month" = Table.AddColumn(#"Inserted Month", "Start of Month", each Date.StartOfMonth([Date]), type date),
  #"Inserted End of Month" = Table.AddColumn(#"Inserted Start of Month", "End of Month", each Date.EndOfMonth([Date]), type date),
  #"Inserted Days in Month" = Table.AddColumn(#"Inserted End of Month", "Days in Month", each Date.DaysInMonth([Date]), Int64.Type),
  #"Inserted Day" = Table.AddColumn(#"Inserted Days in Month", "Day", each Date.Day([Date]), Int64.Type),
  #"Inserted Day Name" = Table.AddColumn(#"Inserted Day", "Day Name", each Date.DayOfWeekName([Date]), type text),
  #"Inserted Day of Week" = Table.AddColumn(#"Inserted Day Name", "Day of Week", each Date.DayOfWeek([Date]), Int64.Type),
  #"Inserted Day of Year" = Table.AddColumn(#"Inserted Day of Week", "Day of Year", each Date.DayOfYear([Date]), Int64.Type),
  #"Inserted Month Name" = Table.AddColumn(#"Inserted Day of Year", "Month Name", each Date.MonthName([Date]), type text),
  #"Inserted Quarter" = Table.AddColumn(#"Inserted Month Name", "Quarter", each Date.QuarterOfYear([Date]), Int64.Type),
  #"Inserted Start of Quarter" = Table.AddColumn(#"Inserted Quarter", "Start of Quarter", each Date.StartOfQuarter([Date]), type date),
  #"Inserted End of Quarter" = Table.AddColumn(#"Inserted Start of Quarter", "End of Quarter", each Date.EndOfQuarter([Date]), type date),
  #"Inserted Week of Year" = Table.AddColumn(#"Inserted End of Quarter", "Week of Year", each Date.WeekOfYear([Date], firstDayofWeek), Int64.Type),
  #"Inserted Week of Month" = Table.AddColumn(#"Inserted Week of Year", "Week of Month", each Date.WeekOfMonth([Date], firstDayofWeek), Int64.Type),
  #"Inserted Start of Week" = Table.AddColumn(#"Inserted Week of Month", "Start of Week", each Date.StartOfWeek([Date], firstDayofWeek), type date),
  #"Inserted End of Week" = Table.AddColumn(#"Inserted Start of Week", "End of Week", each Date.EndOfWeek([Date], firstDayofWeek), type date),
  FiscalMonthBaseIndex = 13-StartofFiscalYear,
  adjustedFiscalMonthBaseIndex = if(FiscalMonthBaseIndex>=12 or FiscalMonthBaseIndex<0) then 0 else FiscalMonthBaseIndex,
  #"Added Custom" = Table.AddColumn(#"Inserted End of Week", "FiscalBaseDate", each Date.AddMonths([Date], adjustedFiscalMonthBaseIndex)),
  #"Changed Type1" = Table.TransformColumnTypes(#"Added Custom", {{"FiscalBaseDate", type date}}),
  #"Inserted Year1" = Table.AddColumn(#"Changed Type1", "Year.1", each Date.Year([FiscalBaseDate]), Int64.Type),
  #"Renamed Columns1" = Table.RenameColumns(#"Inserted Year1", {{"Year.1", "Fiscal Year"}}),
  #"Inserted Quarter1" = Table.AddColumn(#"Renamed Columns1", "Quarter.1", each Date.QuarterOfYear([FiscalBaseDate]), Int64.Type),
  #"Renamed Columns2" = Table.RenameColumns(#"Inserted Quarter1", {{"Quarter.1", "Fiscal Quarter"}}),
  #"Inserted Month1" = Table.AddColumn(#"Renamed Columns2", "Month.1", each Date.Month([FiscalBaseDate]), Int64.Type),
  #"Renamed Columns3" = Table.RenameColumns(#"Inserted Month1", {{"Month.1", "Fiscal Month"}}),
  #"Removed Columns" = Table.RemoveColumns(#"Renamed Columns3", {"FiscalBaseDate"}),
  #"Inserted Age" = Table.AddColumn(#"Removed Columns", "Age", each [Date] - Today, type duration),
  #"Extracted Days" = Table.TransformColumns(#"Inserted Age",{{"Age", Duration.Days, Int64.Type}}),
  #"Renamed Columns4" = Table.RenameColumns(#"Extracted Days", {{"Age", "Day Offset"}}),
  #"Added Custom1" = Table.AddColumn(#"Renamed Columns4", "Month Offset", each (([Year]-Date.Year(Today))*12)
+([Month]-Date.Month(Today))),
  #"Changed Type2" = Table.TransformColumnTypes(#"Added Custom1", {{"Month Offset", Int64.Type}}),
  #"Added Custom2" = Table.AddColumn(#"Changed Type2", "Year Offset", each [Year]-Date.Year(Today)),
  #"Changed Type3" = Table.TransformColumnTypes(#"Added Custom2", {{"Year Offset", Int64.Type}}),
  #"Added Custom3" = Table.AddColumn(#"Changed Type3", "Quarter Offset", each (([Year]-Date.Year(Today))*4)
+([Quarter]-Date.QuarterOfYear(Today))),
  #"Changed Type4" = Table.TransformColumnTypes(#"Added Custom3", {{"Quarter Offset", Int64.Type}}),
  #"Added custom" = Table.AddColumn(#"Changed Type4", "Datekey", each Date.ToText(Date.From([Date]), "yyyyMMdd")),
  #"Changed column type" = Table.TransformColumnTypes(#"Added custom", {{"Datekey", Int64.Type}}),
  #"Added custom 1" = Table.AddColumn(#"Changed column type", "Month-Text", each Text.PadStart( Text.From([Month]), 2, "0")),
  #"Changed column type 1" = Table.TransformColumnTypes(#"Added custom 1", {{"Month-Text", type text}}),
  #"Inserted merged column" = Table.AddColumn(#"Changed column type 1", "Month-Year", each Text.Combine({[#"Month-Text"], Text.From([Year])}, "-"), type text),
  #"Extracted first characters" = Table.TransformColumns(#"Inserted merged column", {{"Month Name", each Text.Start(_, 3), type text}}),
  #"Extracted first characters 1" = Table.TransformColumns(#"Extracted first characters", {{"Day Name", each Text.Start(_, 3), type text}})
in
    #"Extracted first characters 1"

I then added this in DAX , seems to work.

1st Monday of Month = 
IF ('DIM Date Test'[Day Name] = "Mon" && DAY('DIM Date Test'[Date]) < 7 , 1, 0)

Hope it helps
