            DateTime d1 = new DateTime(2017, 6, 10);
            DateTime d2 = new DateTime(2017, 6, 11);

            flag = DateTime.Equals(d1, d2);

            if (flag == true)
                Console.WriteLine("Given dates are equal");
            else
                Console.WriteLine("Given dates are not equal");

            ret = DateTime.Compare(d1, d2);

            if(ret > 0)
                Console.WriteLine("First date is greater");
            else if(ret<0)
                Console.WriteLine("Second date is greater");
            else
