using System.Linq;
using System.Text;

namespace DateTimeDemo
{class Program
    {static void Main(string[] args)
        {
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "Char In use ", "Description ", "Out put"));
            Console.WriteLine(string.Format("{0}", "---------------------------------------------------"));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "d", "Short Format", DateTime.Now.ToString("d")));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "D", "Long Format", DateTime.Now.ToString("D")));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "T", "Long Time", DateTime.Now.ToString("T")));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "t", "short Time", DateTime.Now.ToString("t")));

            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "f", "Full Date and time ", DateTime.Now.ToString("f")));

            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "F", "Full date and Time-Long", DateTime.Now.ToString("F")));

            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "G", "Default date and time -Long", DateTime.Now.ToString("G")));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "g", "Default date and time", DateTime.Now.ToString("g")));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "M", "Day / Month", DateTime.Now.ToString("M")));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "r", "RFC1123 date", DateTime.Now.ToString("r")));
           
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "s     ", "Sortable date/time", DateTime.Now.ToString("s")));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "u     ", "Universal time, local timezone ", DateTime.Now.ToString("u")));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "Y ", "    Month / Year ", DateTime.Now.ToString("Y")));
            
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "ss     ", "seconds ", DateTime.Now.ToString("ss")));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "tt     ", "AM/PM ", DateTime.Now.ToString("tt")));


            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "hh     ", "2 digit hour ", DateTime.Now.ToString("hh")));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "HH     ", "2 digit hour (24 hour)", DateTime.Now.ToString("HH")));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "mm     ", "2 digit minute ", DateTime.Now.ToString("mm")));

            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "dd     ", "Day     08", DateTime.Now.ToString("dd")));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "ddd     ", "Short Day Name ", DateTime.Now.ToString("ddd")));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "dddd     ", "Full Day Name ", DateTime.Now.ToString("dddd")));

            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "MM     ", "Month     ", DateTime.Now.ToString("MM")));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "MMM     ", "Short Month name ", DateTime.Now.ToString("MMM")));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "MMMM     ", "Month name ", DateTime.Now.ToString("MMMM")));
           
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "yy     ", "2 digit year ", DateTime.Now.ToString("yy")));
            Console.WriteLine(string.Format("{0}\t{1}\t{2}", "yyyy", "     4 digit year ", DateTime.Now.ToString("yyyy")));
            
           

            Console.ReadLine();
        }
    }
