DateTime.Subtract() Method in C# Last Updated : 11 Jul, 2025 Comments Improve Suggest changes Like Article Like Report This method is used to subtract the specified time or duration from this instance. There are 2 methods in the overload list of this method as follows: Subtract(DateTime) Subtract(TimeSpan) DateTime.Subtract(DateTime) This method is used to subtract the specified date and time from this instance. Syntax: public TimeSpan Subtract (DateTime value); Return Value: This method returns a time interval that is equal to the date and time represented by this instance minus the date and time represented by value. Exception: This method will give ArgumentOutOfRangeException if the result is less than MinValue or greater than MaxValue. Below programs illustrate the use of DateTime.Subtract(DateTime) Method: Example 1: csharp // C# program to demonstrate the // DateTime.Subtract(DateTime) // Method using System; using System.Globalization; class GFG { // Main Method public static void Main() { try { // creating object of DateTime DateTime date1 = new DateTime(2011, 1, 1, 4, 0, 15); // creating object of DateTime DateTime date2 = new DateTime(2010, 1, 1, 4, 0, 15); // getting ShortTime from DateTime // using Subtract() method; TimeSpan value = date1.Subtract(date2); // Display the TimeSpan Console.WriteLine("TimeSpan between date1"+ " and date2 is {0}", value); } catch (ArgumentOutOfRangeException e) { Console.Write("Exception Thrown: "); Console.Write("{0}", e.GetType(), e.Message); } } } Output: TimeSpan between date1 and date2 is 365.00:00:00 Example 2: csharp // C# program to demonstrate the // DateTime.Subtract(DateTime) // Method using System; using System.Globalization; class GFG { // Main Method public static void Main() { try { // creating object of DateTime DateTime date1 = DateTime.MinValue; // creating object of DateTime DateTime date2 = new DateTime(11119999, 1, 1, 4, 0, 15); // getting ShortTime from DateTime // using Subtract() method; TimeSpan value = date1.Subtract(date2); // Display the TimeSpan Console.WriteLine("TimeSpan between date1 "+ "and date2 is {0}", value); } catch (ArgumentOutOfRangeException e) { Console.Write("Exception Thrown: "); Console.Write("{0}", e.GetType(), e.Message); } } } Output: Exception Thrown: System.ArgumentOutOfRangeException DateTime.Subtract(TimeSpan) This method is used to subtract the specified duration from this instance. Syntax: public DateTime Subtract (TimeSpan value); Return Value: This method returns an object that is equal to the date and time represented by this instance minus the time interval represented by value. Exception: This method will give ArgumentOutOfRangeException if the result is less than MinValue or greater than MaxValue.
