fixed the issue. Will look into that further of course i found a solution right after posting this, thanks for anyone who looked and tried to help. Here is the solution i found: code :
SET DATEFIRST 1
declare @wk int set @wk = 1
declare @yr int set @yr = 2007
select dateadd (week, @wk, dateadd (year, @yr-1900, 0)) - 4 -
datepart(dw, dateadd (week, @wk, dateadd (year, @yr-1900, 0)) - 4) + 1

fixed the issue. Will look into that further You might want to use strptime and strftime methods from datetime: code :
>>> import datetime
>>> datetime.datetime.strptime('January 11, 2010', '%B %d, %Y').strftime('%A')
'Monday'
>>> datetime.datetime.strptime('January 11, 2010', '%B %d, %Y').strftime('%a')
'Mon'

it helps some times I have a column of strings in my data set formatted as year week (e.g. '201401' is equivalent to 7th April 2014, or the first fiscal week of the year) , Try something like this: code :
> test_set <- c('201401', '201402', '201403')
>
> extractDate <- function(dateString, fiscalStart = as.Date("2014-04-01")) {
+ week <- substr(dateString, 5, 6)
+ currentDate <- fiscalStart + 7 * as.numeric(week) - 1
+ currentDate
+ }
>
> extractDate(test_set)
[1] "2014-04-07" "2014-04-14" "2014-04-21"
