• You can first strip the time from the date you are working with.

    This works for me:

    declare @mydate datetime

    set @mydate = GETDATE()

    SELECT DateAdd(day, -1, DATEADD(week, DATEDIFF(week,0,DATEADD(day, DateDiff(day,0,@mydate), 0)), 0))

    Interesting issue. Too bad you have to double the number of calculations you're working with.
