my Date $feb15-grg;
my Date::Calendar::Julian $palindrome-jul;

$feb15-grg      .= new(2020, 2, 15);
$palindrome-jul .= new-from-date($feb15-grg);

say $palindrome-jul;
# --> 2020-02-02
$palindrome-jul.locale = 'nl';
say $palindrome-jul.strftime("%A %e %B %Y");
# --> zaterdag  2 februari 2020

my Str $s1 = $palindrome-jul.strftime("%Y%m%d");
if $s1 eq $s1.flip {
  say "$s1 is a palindrome in YYYYMMDD format!";
}
$s1 = $palindrome-jul.strftime("%d%m%Y");
if $s1 eq $s1.flip {
  say "$s1 is a palindrome in DDMMYYYY format!";
}
$s1 = $palindrome-jul.strftime("%m%d%Y");
if $s1 eq $s1.flip {
  say "$s1 is a palindrome in MMDDYYYY format!";
}
```
