member this.Hour : int

Public ReadOnly Property Hour As Integer

The hour component, expressed as a value between 0 and 23.

The following example demonstrates the Hour property.

System::DateTime moment = 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;

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;

open System


let moment = System.DateTime(1999, 1, 13, 3, 57, 32, 11)

// Year gets 1999.
let year = moment.Year

// Month gets 1 (January).
let month = moment.Month

// Day gets 13.
let day = moment.Day

// Hour gets 3.
let hour = moment.Hour

// Minute gets 57.
let minute = moment.Minute

// Second gets 32.
let second = moment.Second

// Millisecond gets 11.
let millisecond = moment.Millisecond

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

The value of the Hour property is always expressed using a 24-hour clock. To retrieve a string that represents the hour of a date and time using a 12-hour clock, call the DateTime.ToString(String) or DateTime.ToString(String, IFormatProvider) method with the "h" custom format specifier. For example:

DateTime date1 = new DateTime(2008, 4, 1, 18, 53, 0);
Console.WriteLine(date1.ToString("%h"));              // Displays 6
Console.WriteLine(date1.ToString("h tt"));            // Displays 6 PM

let date1 = DateTime(2008, 4, 1, 18, 53, 0)

date1.ToString "%h"
|> printfn "%s"              // Displays 6

date1.ToString "h tt"        
|> printfn "%s"              // Displays 6 PM

Dim date1 As Date = #04/01/2008 6:53:00PM#
Console.WriteLine(date1.ToString("%h"))      ' Displays 6
Console.WriteLine(date1.ToString("h tt"))    ' Displays 6 PM
