Creating a 30/60/90 day column in power bi

Hi Everyone,

How can I create a calculated column in power bi that can look at the past 30/60/90 days?

For something like this, I would recommend doing it in Power Query, in your date table.
NOTE, this means refreshing your data at least once a day

Adding a custom column that looks at the row date and compares it to today’s date, adding the 30, 60, 90 day flag if is hits the criteria.

Here’s the M Code, and I’ve also attached a PBIX so you can see how this is working, the bonus here is that you can use the ranges as a filter since its in your datasource.

let
Source = List.Dates( #date(2020, 7, 1), 180, #duration(1,0,0,0)),
// for this example, source is only to get a list of dates to work with
// (not needed if working with an existing date table)

CurrentDate = DateTime.Date( DateTime.FixedLocalNow ()),
   // Current Date is not connected to any step in this code 
   // (not Source, or Converted to Table) - 
   // it is used IN the "Added Custom" step

#"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}}),
// these steps are not needed if working with an existing date table

#"Added Custom" = Table.AddColumn
  (#"Changed Type", "Past Range", each 
  if [Date] < Date.AddDays( CurrentDate, -90 ) then null else 
  if [Date] <= Date.AddDays( CurrentDate, -60 ) then "90 days" else 
  if [Date] <= Date.AddDays( CurrentDate, -30 ) then "60 days" else 
  if [Date] > CurrentDate then null else "30 days" )
// this is the only step that creates the date ranges - 
// using the Current Date which was added at step two for comparison

in
#“Added Custom”

@Tausif124,

Here is another way to accomplish this in Power Query, if you wish to use those periods in a slicer.
Here is the M Code:

let
    TodaysDate = Date.From(DateTimeZone.FixedUtcNow()),
    Ranges = {
                {"Today", TodaysDate, TodaysDate, 1},
                {"Yesterday", Date.AddDays(TodaysDate,-1), Date.AddDays(TodaysDate,-1), 2},
                {"Last 30 Days",  Date.AddDays(TodaysDate,-30), TodaysDate, 3},
                {"Last 60 Days",  Date.AddDays(TodaysDate,-60), TodaysDate, 4},
                {"Last 90 Days",  Date.AddDays(TodaysDate,-90), TodaysDate, 5}
                                   
             },
    fxCreatePeriodTabe = ( PeriodName as text, StartDate as date, EndDate as date, SortOrder as number ) as table =>
        let
            DayCount = Duration.Days(EndDate-StartDate)+1,
            DateList = List.Dates(StartDate,DayCount,#duration(1,0,0,0)),
            AddPeriodName = List.Transform(DateList, each {PeriodName,_,SortOrder}),
            CreateTable = #table( type table[Period=text, Date=date, Sort=number], AddPeriodName)
        in
            CreateTable,
    
    GetTables = List.Transform(Ranges, each fxCreatePeriodTabe(_{0}, _{1}, _{2}, _{3})),
    Output = Table.Combine(GetTables)
in
    Output

I’ve also attached the PBIX

Hi @Tausif124

Welcome to the forum.

I just want to share another approach using DAX. You can use those periods in Slicer.
