Start counting week from a fixed date

Hi friends,

 

i want to visualize the perfomance of the new joinees on the basis of weeks, Week will start from the date of joining. for example if Steve joins on 2021-08-01 the i need the next seven days as week 1 and then Next 7 to 14 days as week 2 and so on.

 

I tried to use WEEKNUM but it is counting weeks from year start. 

Any help would be highly appreciated as i've just started in power bi.

Hi @AjaySingh

Weeknum() returns a fixed value, so try another way, 

e.g. 

Steve  join date:2021/9/1,
week1:2021/9/1-2021/9/7,
week2:2021/9/8-2021/9/14,
week3:2021/9/15-2021/9/21,
...

Weeknum = 
    var _joinDate=DATE(2021,9,1)
    var _duration=DATEDIFF(_joinDate,MIN('Table'[Column1]),DAY)
return INT(_duration/7)+1

result
