Date::Calc and Date::Manip are both available from the ActiveState PPM Repository. I'd seriously suggest that your client install these.

If that's absolutely positively impossible, then you're stuck with something like the following: 

my $day = (localtime())[7];
my $week_num = int($day/7) + 1;

Come to think of it, that's not so bad after all.
