Hi Monks,
I want to check if two given dates have a difference of maximum 6 months. I go about like this:
use Date::Calc qw(:all);
use strict;

my @data_date_confirm=();
my @data_date_birth=();

my $diab_confirm = '29/08/2013';
my $date_birth = '21/02/2013';
    if($diab_confirm=~/(\d+)\/(\d+)\/(\d+)/) 
    {
        my $day_confirm = $1;
        my $month_confirm = $2;
        my $year_confirm = $3;

        @data_date_confirm = ($year_confirm, $month_confirm, $day_conf
+irm);
    }

    if($date_birth=~/(\d+)\/(\d+)\/(\d+)/) 
    {
        my $day_birth = $1;
        my $month_birth = $2;
        my $year_birth = $3;

        @data_date_birth = ($year_birth, $month_birth, $day_birth);
    }

    my $dd = Delta_Days(@data_date_birth, @data_date_confirm);
    my $months_until_confirm = sprintf("%.1f", $dd/30);
    
    if($months_until_confirm<=6)
    {
        print "They are different by more than 6 months!\n";
    }

I realise though that this is not entirely correct, since I divide by 30 days. Is it a way to be more precise?
Thank you!
