DateTime.Hour Property

Definition

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

C#
public int Hour { get; }

Property Value

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

Examples

The following example demonstrates the Hour property.

C#
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;

Remarks

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:

C#
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
