using System;
using System.Collections.Generic;
using System.Linq;

namespace ABC119A
{
    static class MainClass
    {

        static string[] s;
        static int[] n;

        public static void Main(string[] args)
        {

            s = Console.ReadLine().Split().ToArray();
            DateTime d = DateTime.Parse(s[0]);

            if (d <= DateTime.Parse("2019/04/30"))
            {
                Console.WriteLine("Heisei");
            }
            else
            {
                Console.WriteLine("TBD");
