Dynamically calculate a calendar maintenance table based on a start date

Here is an example of the one for Months.  If it works, you could adapt the approach for weeks and quarters.  To see how it works, just create a blank query, go to Advanced Editor, and replace the text there with the M code below.  This could easily be converted into a function where you could just input the desired start date.

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMtI31DcyMDJQio0FAA==", 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}}),
Date = #"Changed Type"{0}[Date],
Custom1 = List.Transform({0..Number.RoundUp(Duration.Days(Date.EndOfYear(Date)-Date)/30)-2}, each Date.AddMonths(Date, _)),
#"Converted to Table" = Table.FromList(Custom1, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
#"Renamed Columns" = Table.RenameColumns(#"Converted to Table",{{"Column1", "RefreshDates"}}),
#"Changed Type1" = Table.TransformColumnTypes(#"Renamed Columns",{{"RefreshDates", type date}})
in
#"Changed Type1"

If this works for you, please mark it as the solution.  Kudos are appreciated too.  Please let me know if not.
