I think the original poster's code only gets files within the directory, not subdirectories. If the subdirectories are needed, then you could do a recursive solution, like - 
use File::Find;
@ARGV = ('.') unless @ARGV;  #start at . unless given 
                             # as command line argument
sub ProcessFiles {
    &CheckAndFixFile($File::Find::name);
}
find(\&ProcessFiles, @ARGV);  # find is recursive

sub CheckAndFixFile {
    my $filename = shift @_;
    #Put code here to check if $filename meets criteria, and delete li
+ne if needed.
}

The CheckAndFixFile subroutine is where you would use Date::Manip, or whichever Date module you like, to compare dates. It's easier than writing your own regular expression, as you did in your post, and it's code that's been tested and works.
