One of the problems is that "current week of the year" is not a
well-defined term.  Some companies define the first week as the week that
contains January 1.  Some companies define the first week as the first full
week, so that a partial Jan 1 week is actually part of the previous year.
And you get the whole "does the week start on Sunday or Monday" debate as
well.

You need to make sure that the datetime functions match your business
rules.
