16.1 Formatting Date and time using predefined formats

In Visual Basic 2010, date and time can be formatted using predefined formats and also user-defined formats.

* Instead of “General date”, you can also use the abbreviated format “G” , i.e. Format (Now, “G”). And for “Long Time”, you can use the abbreviated format “T”. As for “Short Time”, you may use the abbreviated format “t”




The predefined formats of date and time are shown in Table 16.1.

Example 16.1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

 Label2.Text = Format(Now, "Long Date")
 Label3.Text = Format(Now, "short Date")
