I need a SQL server Func that will calculate a complete date from the week of the year : <p>I need to calculate to a string of dd-MM-yyyy </p>

<p>From a wwyy string (I need the first day of the week or any other day of the week)</p>

<p>for exmpl: Now we are in week 42 of 18 so if I'll enter 4218
I'll get 15-10-2018 or 14-10-2018</p>

<p>BR,
Idan</p>
