I need to calculate week number of the month using MS SQL sample input and output given below 

```
01/04/2016(Friday)  1 (1st week),
04/04/2016(Monday)  2 (2nd week), 
11/04/2016(Monday)  3 (3rd week) 

```

I need output like this
Consider Sunday as week starting date and Saturday as week ending date
I think this examples are clear 

Thanks
