DateTime.Year Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets the year component of the date represented by this instance.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public ReadOnly Property Year As Integer

public int Year { get; }

Property Value

Type: System.Int32
The year component, expressed as a value between 1 and 9999.

Remarks

The Year property returns the year of the current instance in the Gregorian calendar. It does not return the year using the default calendar of the current culture. To retrieve the year using a particular calendar, you can call that calendar's GetYear method. The following example, which assumes that the target computer's current culture is th-TH, illustrates this.

Imports System.Globalization

Module Example
   Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      ' Initialize date variable and display year
      Dim date1 As Date = #1/1/2008 6:32:00 AM#
      outputBlock.Text &= date1.Year & vbCrLf       ' Displays 2008

      ' display year using current culture's calendar 
      Dim thaiCalendar As Calendar = CultureInfo.CurrentCulture.Calendar
      outputBlock.Text &= thaiCalendar.GetYear(date1) & vbCrLf    ' Displays 2551
   End Sub
End Module

using System;
using System.Globalization;
using System.Threading;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      // Initialize date variable and display year
      DateTime date1 = new DateTime(2008, 1, 1, 6, 32, 0);
      outputBlock.Text += date1.Year + "\n";                    // Displays 2008

      outputBlock.Text += date1.Year + "\n";                    // Displays 2008

      // display year using current culture's calendar 
      Calendar thaiCalendar = CultureInfo.CurrentCulture.Calendar;
      outputBlock.Text += thaiCalendar.GetYear(date1) + "\n";   // Displays 2551
   }
}

Examples

The following example demonstrates the Year property.

Dim moment As New System.DateTime(1999, 1, 13, 3, 57, 32, 11)

' Year gets 1999.
Dim year As Integer = moment.Year

' Month gets 1 (January).
Dim month As Integer = moment.Month

' Day gets 13.
Dim day As Integer = moment.Day

' Hour gets 3.
Dim hour As Integer = moment.Hour

' Minute gets 57.
Dim minute As Integer = moment.Minute

' Second gets 32.
Dim second As Integer = moment.Second

' Millisecond gets 11.
Dim millisecond As Integer = moment.Millisecond

System.DateTime moment = new System.DateTime(
                        1999, 1, 13, 3, 57, 32, 11);
// Year gets 1999.
int year = moment.Year;

// Month gets 1 (January).
int month = moment.Month;

// Day gets 13.
int day = moment.Day;

// Hour gets 3.
int hour = moment.Hour;

// Minute gets 57.
int minute = moment.Minute;

// Second gets 32.
int second = moment.Second;

// Millisecond gets 11.
int millisecond = moment.Millisecond;
