            string time = Console.ReadLine();

            byte hour = byte.Parse(time[0].ToString() + time[1].ToString());
            byte mins = byte.Parse(time[2].ToString() + time[3].ToString());
            if (hour == 21 || hour == 22 || hour == 23 || hour == 00 || hour == 01 || hour == 02 || hour == 03)
            {
                if (mins < 60 && mins >= 0)
                {
                    if (hour == 03 && mins > 00)
                        Console.WriteLine("Invalid");
                    else if (hour == 21 && mins < 01)
                        Console.WriteLine("Invalid");
                    else
                        Console.WriteLine("Valid");
                }
                else
                    Console.WriteLine("Invalid");
            }
            else
                Console.WriteLine("Invalid");
            
            Console.ReadLine();

This code works... it's self explanatory.
There might be (which I am like 99% sure there is) a more compact version of this code.. but hey.. this one works!

Made it in like 2 mins... should be beginner stuff...
