Some creative urge over took me and i figured out the date calculations to go with your HTML output! ;)

use strict;
use warnings;

use Data::Dumper;
use CGI::Pretty qw(:standard start_table end_table start_Tr end_Tr), (
+-unique_headers);
#use CGI::Carp qw(fatalsToBrowser);

use Date::Calc  qw(Week_of_Year Monday_of_Week Add_Delta_Days Standard
+_to_Business);
my @day    = (2007,2,10);
my @week   = Week_of_Year(@day);

my @weeks = [];
for my $delta  (-15..15) {
    my @n_day   = Add_Delta_Days(@day,$delta);

    #calculate which week we are in
    my @n_week  = Week_of_Year(@n_day);

    #calculate the day of the week
    my @b_day   = Standard_to_Business(@n_day);

    #put it in a nice array of arrayref
    $weeks[$n_week[0]]->[$b_day[2]-1] = $n_day[2];
}

# this seemed easier than calculating the smallest week 
# number and subtracting that from each index
@weeks = grep {defined} @weeks;

print header();
print start_html (-title => "Calendar sample");

my @weekDays = qw(Mon Tue Wed Thur Fri Sat Sun);

print start_table();
print Tr ({-align=>'CENTER',-valign=>'TOP'}, td (\@weekDays));
for my $week (@weeks) {
     print start_Tr({-align=>'CENTER',-valign=>'TOP'});
     for my $date (@$week) {
          if (! defined $date) {
               print td ('');
          } elsif ($date == $day[2]) {  
               print td(strong($date));  
          } else {
               print td ($date);
          }
     }
     
     print end_Tr();
}      

print end_html ();
