## Previous Week DAX

Hello everyone, hope you're doing well.

I have an issue regarding Previous Week calculation using DAX. I have sales table that is represented in the weekly basis. How can I calculate the Previous Week Sales since it's more challenging using Standard Date Table?
The purpose of why I want to calculate the previous week is to be a baseline to calculate Current Week vs Previous Week Sales, Current Week vs Same Week in the last month.

Please kindly find the attached link into the PBIX file. Really appreciate your help and support. Thank You!

Hi,

Not sure what you want the answer to be but i get 6000 with this edited measure

``Total Sales Last Week = CALCULATE([Total Sales],DATESBETWEEN('Calendar'[Date],MAX('Calendar'[Date])-6,MAX('Calendar'[Date])))``

Hope this helps.

Hi Ashish, Thanks for replying! The questions are:
1) How to show the value of last week? since in the PBIX file, specifically in the Card Visual, the previous week sales is a cumulative of previous week in March
2) How can I calculate the Current Week vs Same Week in the Last Month?

Thank you!
