Given a date, how do you tell which week in the month is that date?
EG : Given 1-Feb-2005, it is the 1st week in February.
Given 17-Feb-2005, it is the 3rd week in February.

declare @startOfMonth datetime
declare @myDate datetime
declare @weekOfYearForStartOfMonth int
declare @weekInMonth int

select @myDate = '17-feb-2005'
select @startOfMonth = dateadd(d, (day(@myDate)-1)* -1, @myDate)
select @weekOfYearForStartOfMonth = datepart(ww, @startOfMonth)
select datepart(ww, @myDate) - @weekOfYearForStartOfMonth + 1
