I am trying to fix some display issues with dates, but for some reason I can't figure it out why my code isn't working on today's date, here is what I have, I just can't see where the problem is, and why today's date is matching on L1, since I have to digits starting the first part of the date value,

First, I had some difficulties reading your code. Thus I reformatted it, with no substantial modification:

my $date = "10/13/2006";
if ($date=~/(\d{1})\/(\d{2})\/(\d{4})/) {
    $date="0".$1."\/".$2."\/".$3;
    print "<br>L1 - $date<br>";
    
} elsif ($date=~/(\d{2})\/(\d{1})\/(\d{4})/) {
    $date=$1."\/0".$2."\/".$3;
    print "<br>L2 - $date<br>";
} else {
    $date=~/(\d{1})\/(\d{1})\/(\d{4})/;
    $date="0".$1."\/0".$2."\/".$3;
    # no print here?!?    
}

So it seems that you want to "normalize" month and day to two digits. Then I would switch logic altogether:

my $date = "10/13/2006";
my ($m,$d,$y)=split m(/), $date;
$date=join '/', (map sprintf('%02d', $_), $m, $d), $y;

Update: I don't have the slightest idea of what I was thinking of, but I was reinventing the wheel myself, using awkward logic to implement something that sprintf offers out of the box in the first place:

my $date = "10/13/2006";
$date=sprintf '%02d/%02d/%d', split m(/), $date;

Of course this does not do full validation of the initial $date but that's something you can add easily once you have $m, $d and $y. So I don't know why your code "doesn't work" for today's date, but the lesson is, I hope: do not reinvent the wheel!
