Solution in Perl (v5.18.2) (judge verdict: Accepted)

use v5.18;
use warnings;
sub read_line { chomp(my $s = <>); $s }
sub splited_read_line { split / /, read_line }

my ($y, $m, $d) = split /\//, read_line;
say do {
  if ( $y < 2019 ) {
    'Heisei';
  }
  elsif ( $y == 2019 ) {
    $m <= 4 ? 'Heisei' : 'TBD';
  }
  else {
    'TBD';
  }
};
