    First go to query editor >create an index column;

    Then create 2 columns as below:

    rankx = RANKX(FILTER('Table',MOD('Table'[Index],4)=0),'Table'[Index],,ASC)
    4 Wk Ended = 
var _mindate=CALCULATE(MIN('Table'[Time]),FILTER('Table','Table'[rankx]=EARLIER('Table'[rankx])))
Return
_mindate+21

    And you will see:

ryan_b_fiting , You can create a date table, and there you can create week start and week end is +28 days.

and create a bucket based on that.

 

example , new columns in date table

Week Start date = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+1
Week End date = [Week Start date] +4
Week = if('Date'[Week Number]<10,'Date'[Year]*10 & 'Date'[Week Number],'Date'[Year]&'Date'[Week Number])

of you can get on the week start date and create 4-week period post that

Min Week Start date = min([Week Start date])

4 Week No = Quotient(datediff([Min Week Start date],date,day),28)+1
