How to make weekly data

Hello,

So I have a date column in my table; however, I need to create a measure or column that gives the week number of every month and resets every month. For example, the first 7 days in june correspond to 1, and the next 7 days correspond to 2 (week 2). I have been trying to figure this out for a long time, but with no hope and I am a beginner in the software. I would really appreciate your help, thank you!!
