begin

declare @WeekOfYear int

select
— Compute week of year as (days since start of year/7)+1
— Division by 7 gives whole weeks since start of year.
— Adding 1 starts week number at 1, instead of zero.
@WeekOfYear =
(datediff(dd,
— Case finds start of year
case
when NextYrStart <= @date
then NextYrStart
when CurrYrStart <= @date
then CurrYrStart
else PriorYrStart
end,@date)/7)+1

CurrYrStart =
dateadd(dd,(datediff(dd,-53690,aa.Jan4)/7)*7,-53690),

Otherwise your dependent on the settings on the server.

Note that all your TIME and DATEs are just VARCHARs
You should do this formation in the front end application

or

If you use SQL Server 2008, make use of new datatypes Time and Date
