Answer 1

add to cron
minute hour day month day-of-week <command>
or in C# create a timer and check the current date every second, something like this

using System;
using System.Timers;

public class Demo {
   private static Timer timer;

   public static void Main() {
      timer = new System.Timers.Timer();
      timer.Interval = 1000;

      timer.Elapsed += OnTimedEvent;
      timer.AutoReset = true;
      timer.Enabled = true;

      Console.WriteLine("Press the Enter key to exit anytime... ");
      Console.ReadLine();
   }

   private static void OnTimedEvent(Object source, System.Timers.ElapsedEventArgs e) {
      Console.WriteLine("Raised: {0}", e.SignalTime);
   }
}
