It's defined in the docs...
=item * %V
The ISO 8601:1988 week number of the current year as a decimal number,
range 01 to 53, where week 1 is the first week that has at least 4
days in the current year, and with Monday as the first day of the
week. See also %U and %W.
'U' => sub { my $dow = $_[0]->day_of_week;
$dow = 0 if $dow == 7; # convert to 0-6, Sun-Sat
my $doy = $_[0]->day_of_year - 1;
return int( ( $doy - $dow + 13 ) / 7 - 1 )
},
But it's not here...
'w' => sub { my $dow = $_[0]->day_of_week;
return $dow % 7;
},
Was it documented and then not implemented?
