Solution in C# (Mono 4.6.2.0) (judge verdict: Wrong Answer)

using System;


namespace StillTBD
{
    class Program
    {
        public static void Main(string[] args)
        {
            Console.WriteLine("yyyy/mm/dd 形式で入力して下さい");
            var time = "2019/04/30";
            DateTime dateTime = DateTime.Parse(Console.ReadLine());
            DateTime compTime = DateTime.Parse(time);

            if (dateTime.CompareTo(compTime) == -1 || dateTime.CompareTo(compTime) ==0)
            {
                Console.Write("Heisei");
            }
            else
            {
                Console.Write("TBD");
            }

        }
    }
