The GetDaylightChanges method returns specific daylight saving information for a given year:

   
  

using System;
using System.Globalization;
public class MainClass {
    public static void Main() {
        TimeZone zone = TimeZone.CurrentTimeZone;
        DaylightTime day = zone.GetDaylightChanges(2008);
        Console.WriteLine(day.Start);
        Console.WriteLine(day.End);
        Console.WriteLine(day.Delta);
    }
}
