Determine Weekday Of Date

The code is ok until I hit a month with 4weeks in it and days left over.
The code puts a week total in place of a Sunday, but as some months end before a Sunday appears the code just builds a Month end total sheet.

What I need in this case is a Week total even if there is no Sunday before it builds the Month end Total.

I hope i'm being clear

Sub NewSheets()
Dim Dte As Date, Dy As Date
Dim i As Long, j As Long, Dys As Long
Dim CountWeek As Boolean
Dim Shts As Long...
