Calculating Sales Per Week (Partial)

[Tuan]

I'm trying to calculate Sales Per Week. The problem i'm having is the Partial weeks since im using a Regular Calendar Year.

Since there are only 2 days in week 27 for June, I was trying to get the June month to use 4.28 as the denominator instead of 5.

I've been wracking my brain on how to calculate this.

My Data is as follows.

@Tuan , You can try divide by distinct count of date

divide(sum(Table[New Sales]),distinctcount(Table[Sales Date]))

Prefer to Date table and have Week there

Assuming you have a Date table, you can just use 

Weeks = COUNTROWS('Date'[Date])/7

If you don't have a Date table, and potentially have no rows on some dates, you could use

Weeks = (DATEDIFF(MIN(Table[Date]), MAX(Table[Date]), DAY)+1)/7

If this works for you, please mark it as the solution.  Kudos are appreciated too.  Please let me know if not.
