ellem,
The solution I am providing is applicable to field swapping.
If you need to do real date manipulation, I suggest:
  • Date::Calc
  • Date::Manip
  • Time::Local

    This is OWTDI - there are plenty though: 

    #!/usr/bin/perl -w
use strict;
while (<DATA>) {
   chomp;
   my @fields = split "/" , $_;
   print join "/" , @fields[1,2,0];
   print "\n";  
}
__DATA__
74/05/25
54/03/04
69/08/23
55/08/24

    Hope this gets you pointed in the right direction!
    Cheers and happy hacking - L~R
