How do I find the week-of-the-year/day-of-the-year?by faq_monk (Initiate)

Current Perl documentation can be found at perldoc.perl.org.
Here is our local, out-dated (pre-5.6) version:
The day of the year is in the array returned by
$day_of_year = (localtime(time()));
or more legibly (in 5.004 or higher):
use Time::localtime; $day_of_year = localtime(time())->yday;
You can find the week of the year by dividing this by 7:
$week_of_year = int($day_of_year / 7);
Of course, this believes that weeks start at zero. The Date::Calc module from CPAN has a lot of date calculation functions, including day of the year, week of the year, and so on. Note that not all business consider ``week 1'' to be the same; for example, American business often consider the first week with a Monday in it to be Work Week #1, despite ISO 8601, which consider WW1 to be the frist week with a Thursday in it.
