Creating a dates table is a universal problem when working with data analysis tools. Here’s a quick solution to this eternal problem.

Create a Parameter for the Start Date

Name this value StartDateParameter. Set this value to 01-Jan-1900.

#date(1900, 1, 1) meta [IsParameterQuery=true, Type="Date", IsParameterQueryRequired=true]

Create a Parameter for the End Date

Name this value EndDateParameter. Set this value to 31-Dec-2999. Of course, you can change the end date if this value does not suit your application needs.

#date(2999, 12, 31) meta [IsParameterQuery=true, Type="Date", IsParameterQueryRequired=true]

Create a Parameter for Duration

Name this value DurationParameter. Set the value to 1 day.

#duration(1, 0, 0, 0) meta [IsParameterQuery=true, Type="Duration", IsParameterQueryRequired=true]

Create a Data Set for Dates

Create a new Blank Query. Open the Advanced Editor and paste in the following text. As you can see, we use StartDateParameter and EndDateParameter to set the bounds for our Dates data set. We use DurationParameter to create the list of dates.

    DayCount = Duration.Days(Duration.From(EndDateParameter - StartDateParameter)),
    Source = List.Dates(StartDateParameter, DayCount, DurationParameter),
    TableFromList = Table.FromList(Source, Splitter.SplitByNothing()),
    RenameColumn1 = Table.RenameColumns(TableFromList, { {"Column1", "Date"} }),
    ChangeDateType = Table.TransformColumnTypes(RenameColumn1, { {"Date", Date.Type} }),
    AddYear = Table.AddColumn(ChangeDateType, "Year", each Date.Year([Date]), Int32.Type),
    AddMonth = Table.AddColumn(AddYear, "Month", each Date.Month([Date]), Int32.Type),
    AddDay = Table.AddColumn(AddMonth, "Day", each Date.Day([Date]), Int32.Type),
    AddDayOfWeek = Table.AddColumn(AddDay, "DayOfWeek", each Date.DayOfWeek([Date]), Int32.Type),
    AddWeekday = Table.AddColumn(AddDayOfWeek, "Weekday", each Date.DayOfWeekName([Date]), Text.Type),
    AddMonthName = Table.AddColumn(AddWeekday, "MonthName", each Date.MonthName([Date]), Text.Type),
    AddShortWeekday = Table.AddColumn(AddMonthName, "ShortWeekday", each Text.Start([Weekday], 3), Text.Type),
    AddShortMonthName = Table.AddColumn(AddShortWeekday, "ShortMonthName", each Text.Start([MonthName], 3), Text.Type),
    AddStartOfMonth = Table.AddColumn(AddShortMonthName, "StartOfMonth", each Date.StartOfMonth([Date]), Date.Type),
    AddEndOfMonth = Table.AddColumn(AddStartOfMonth, "EndOfMonth", each Date.EndOfMonth([Date]), Date.Type),
    AddDaysInMonth = Table.AddColumn(AddEndOfMonth, "DaysInMonth", each Date.DaysInMonth([Date]), Int32.Type),
    AddDayOfYear = Table.AddColumn(AddDaysInMonth, "DayOfYear", each Date.DayOfYear([Date]), Int32.Type),
    AddIsLeapYear = Table.AddColumn(AddDayOfYear, "IsLeapYear", each Date.IsLeapYear([Date]), Logical.Type),
    AddDaysInYear = Table.AddColumn(AddIsLeapYear, "DaysInYear", each if [IsLeapYear] then 366 else 365),
    AddQuarter = Table.AddColumn(AddDaysInYear, "Quarter", each Date.QuarterOfYear([Date]), Int32.Type),
    AddMM = Table.AddColumn(AddQuarter, "MM", each Text.End("0"&Text.From([Month]), 2), Text.Type),
    AddDD = Table.AddColumn(AddMM, "DD", each Text.End("0"&Text.From([Day]), 2), Text.Type),
    AddDDD = Table.AddColumn(AddDD, "DDD", each Text.End("00"&Text.From([DayOfYear]), 3)),
    AddMMDDYYYY = Table.AddColumn(AddDDD, "MM.DD.YYYY", each [MM]&"/"&[DD]&"/"&Text.From([Year])),
    AddDDMMYYYY = Table.AddColumn(AddMMDDYYYY, "DD.MM.YYYY", each [DD]&"/"&[MM]&"/"&Text.From([Year]), Text.Type),
    AddYYYYDDD = Table.AddColumn(AddMMDDYYYY, "YYYY.DDD", each Text.From([Year])&"/"&[DDD], Text.Type),
    AddYYYYQ = Table.AddColumn(AddYYYYDDD, "YYYY.Q", each Text.From([Year])&"/"&Text.From([Quarter]), Text.Type),
    SortTable = Table.Sort(AddYYYYQ, {"Year", "Month", "Day"})

That’s it! Apply the changes to your model. You now have a table of dates for your next Power BI project.
