public:
 static int Day(DateTime DateValue);
public static int Day (DateTime DateValue);
static member Day : DateTime -> int
Public Function Day (DateValue As DateTime) As Integer

Parameters

DateValue
DateTime DateTime DateTime DateTime

Required. A Date value from which you want to extract the day.

Returns

An integer value from 1 through 31 representing the day of the month.

Examples

The following example uses the Day function to obtain the day of the month from a specified date. In the development environment, the date literal is displayed in standard short format (such as "02/12/1969") using the locale settings of your code.

Dim oldDate As Date
Dim oldDay As Integer
' Assign a date using standard short format.
oldDate = #2/12/1969#
oldDay = Microsoft.VisualBasic.DateAndTime.Day(oldDate)
' oldDay now contains 12.

Day is qualified to distinguish it from the System.Windows.Forms.Day enumeration.

Remarks

If you use the Day function, you might have to qualify it with the Microsoft.VisualBasic namespace, because the System.Windows.Forms namespace defines Day as an enumeration. The following example shows how qualifying Day resolves this ambiguity:

Dim thisDay As Integer = Microsoft.VisualBasic.DateAndTime.Day(Now)  

You can also obtain the day of the month by calling DatePart and specifying DateInterval.Day for the Interval argument.
