week data

Anonymous ,For week you have WEEKNUM([Date],2) or WEEKNUM([Date],1)

////////////////////////////////////

Typically We Join the date (call closed) with date table. There we will date , month, week , year etc and we will group date in visual by that.

In case of date has a timestamp. Then we create the only date

call closed Date = [call closed].date

You can have column in your date table

Month Year = FORMAT([Date],"mmm-yyyy")
Month Year sort = FORMAT([Date],"yyyymm")

Year = FORMAT([Date],"YYYY" )

Qtr No = FORMAT([Date],"Q")
Qtr = FORMAT([Date],"YYYY") & "-Q" & FORMAT([Date],"Q")	

Week Start date = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+1
Week End date = 'Date'[Date]+ 7-1*WEEKDAY('Date'[Date],2)
Week Number = WEEKNUM([Date],2)
Week Rank = RANKX(all('Date'),'Date'[Week Start date],,ASC,Dense)
