You can also use DateTime :) Here's an example of something close enough Re: Re: Get date interval from week of year -> Date::Manip

update: here's a direct example

use strict;
use warnings;

use DateTime;


my $now = DateTime->now;
#$now = DateTime->new( year => 1960, month => 3, day => 19 );

my $mon = $now->clone->subtract(
    days => $now->day_of_week_0,
);

my $sun = $mon->clone->add(
    days => 6,
);

printf
    "   Today is %s (%d) %s $/",
        $now->ymd,
        $now->day_of_week,
        $now->day_name,
        ;

printf
    "Week begins %s (%d) %s $/",
        $mon->ymd,
        $mon->day_of_week,
        $mon->day_name,
        ;


printf
    "  Week ends %s (%d) %s $/",
        $sun->ymd,
        $sun->day_of_week,
        $sun->day_name,
        ;
