DateTime.IsDaylightSavingTime() Method in C#

The DateTime.IsDaylightSavingTime() method in C# is used to indicate whether this instance of DateTime is within the daylight saving time range for the current time zone.

Syntax

Following is the syntax −

public bool IsDaylightSavingTime ();

Example

Let us now see an example to implement the DateTime.IsDaylightSavingTime() method −

using System;
public class Demo {
   public static void Main() {
      DateTime d = new DateTime(2019, 10, 11, 7, 10, 40);
      bool res = d.IsDaylightSavingTime();
      if (res)
         Console.WriteLine("TRUE: This instance of DateTime is within the daylight saving time range for the current time zone.");
      else
         Console.WriteLine("FALSE: This instance of DateTime is within the daylight saving time range for the current time zone.");
   }
}

Output

This will produce the following output −

FALSE: This instance of DateTime is within the daylight saving time range for the current time zone.

Example

Let us now see another example to implement the DateTime.IsDaylightSavingTime() method −

using System;
public class Demo {
   public static void Main() {
      DateTime d = DateTime.Now;
      bool res = d.IsDaylightSavingTime();
      if (res)
         Console.WriteLine("TRUE: This instance of DateTime is within the daylight saving time range for the current time zone.");
      else
         Console.WriteLine("FALSE: This instance of DateTime is within the daylight saving time range for the current time zone.");
   }
}

Output

This will produce the following output −

FALSE: This instance of DateTime is within the daylight saving time range for the current time zone.
