Custom Weeknum

Hello,

 

I'm trying to create a column with custom week numbers (Operating periods) that end in the dates below:

 

1/1/2022 - 1/12/2022  - Week 1

1/13/2022 - 1/19/2022  - Week 2
1/20/2022 - 1/26/2022 - Week 3

Until the last week of the year. 


Any ideas on how I can accomplish this? I a pprecite your help!

  • To close the loop on this, this is what ended up working:

     

    Operating Period = WEEKNUM('Calendar'[Date]+4, 21)-1

     

    It gave me this: 

     

    To correct the first 5 days of the week that defaulted to Operating Period 0, I added this:

     

    Operating Periods = if('Calendar'[Operating Period] = 0,1,WEEKNUM('Calendar'[Date]+4, 21)-1)

     

    The result was this, which is what I needed:

    NPC What is the pattern? Is the first week 1/1 - 1/12 and then each week is the next 7 days? You could do something like maybe: WEEKNUM([Date],14) ? 14 starts weeks on Thursday.

      Unfortunatley with this approach week 1 ends on 1/5. To answer your question though, yes - each week is the next 7 days after the first 12 days of the year.
