Full Date Short Time ("f") Format Specifier in C#

The Full Date Short Time ("f") format specifier in C# represents a combination of the long date ("D") and short time ("t") patterns. It displays the complete date information along with hours and minutes in a readable format.

This format specifier is culture-sensitive and will display dates according to the specified culture's formatting conventions.

Syntax

Following is the syntax for using the "f" format specifier −

DateTime.ToString("f")
DateTime.ToString("f", CultureInfo.CreateSpecificCulture("culture-code"))

Using "f" Format Specifier with Default Culture

Example

using System;

class Demo {
   static void Main() {
      DateTime myDate = new DateTime(2018, 8, 29, 13, 45, 30);
      Console.WriteLine("Full Date Short Time: " + myDate.ToString("f"));
      
      DateTime currentDate = DateTime.Now;
      Console.WriteLine("Current Date: " + currentDate.ToString("f"));
   }
}

The output of the above code is −

Full Date Short Time: Wednesday, August 29, 2018 1:45 PM
Current Date: Monday, December 16, 2024 2:30 PM

Using "f" Format Specifier with Different Cultures

Example

using System;
using System.Globalization;

class Demo {
   static void Main() {
      DateTime myDate = new DateTime(2018, 8, 29, 1, 10, 0);
      
      Console.WriteLine("US Format: " + myDate.ToString("f", CultureInfo.CreateSpecificCulture("en-US")));
      Console.WriteLine("UK Format: " + myDate.ToString("f", CultureInfo.CreateSpecificCulture("en-GB")));
      Console.WriteLine("German Format: " + myDate.ToString("f", CultureInfo.CreateSpecificCulture("de-DE")));
      Console.WriteLine("French Format: " + myDate.ToString("f", CultureInfo.CreateSpecificCulture("fr-FR")));
   }
}

The output of the above code is −

US Format: Wednesday, August 29, 2018 1:10 AM
UK Format: 29 August 2018 01:10
German Format: Mittwoch, 29. August 2018 01:10
French Format: mercredi 29 août 2018 01:10

Comparison with Other Date Format Specifiers

Practical Usage Example

Example

using System;
using System.Globalization;

class EventScheduler {
   static void Main() {
      DateTime[] events = {
         new DateTime(2024, 12, 25, 10, 30, 0),
         new DateTime(2024, 7, 4, 14, 15, 0),
         new DateTime(2024, 1, 1, 0, 0, 0)
      };
      
      Console.WriteLine("Upcoming Events:");
      Console.WriteLine("================");
      
      foreach (DateTime eventDate in events) {
         Console.WriteLine("Event Date: " + eventDate.ToString("f"));
      }
   }
}

The output of the above code is −

Upcoming Events:
================
Event Date: Wednesday, December 25, 2024 10:30 AM
Event Date: Thursday, July 4, 2024 2:15 PM
Event Date: Monday, January 1, 2024 12:00 AM
