## Custom Week Number

Hi
I want to create a custom week column for my financial year (August to July).
FY 2019 is 1st Aug 2019 to 31st July 2020
FY 2020 is 1st Aug 2020 to 31st July 2021
First of August is the first day a week. Second week starts on 8th of August and so on...
Help me create a column.

Try columns like

Date = CALENDAR(date(2014,01,01),date(2020,12,31))
Week Start Date with Year = var _1 =QUOTIENT(DATEDIFF(STARTOFYEAR('Date'[Date],"7/31"),'Date'[Date],DAY),7) return STARTOFYEAR('Date'[Date]) + if(_1<52,_1,51)*7
Week No = var _1=  QUOTIENT(DATEDIFF(STARTOFYEAR('Date'[Date],"7/31"),'Date'[Date],DAY),7)+1 return if(_1<52,_1,52)
Week Day = MOD(DATEDIFF('Date'[Week Start Date with Year],[Date],DAY),7)+1
