I might be missing something, but I don't see a function in Date::Calc. Here's a DateTime solution:

use DateTime;
my $dt = DateTime->now;
my $date = $dt->strftime("%b %Y");
my $week = $dt->week_of_month();
print "It is Week: $week As of $date\n";
__END__
It is Week: 2 As of Oct 2017

However, note that the week number returned here can be zero - from the DateTime docs on week_of_month:

The first week of the month is the first week that contains a Thursday. This is based on the ICU definition of week of month, and correlates to the ISO8601 week of year definition. A day in the week before the week with the first Thursday will be week 0.

So you need to have a clear definition of what the Nth week means for you. (Update: LanX made the same point here.)
