What have you tried till now?
What is "label validation"?

Take a look at past answers: How to program a countdown timer in VB.NET[^]
Without the relevant code we can;t tell you how to fix this.
But ... this is what I'd do.
Set up a Timer on a half-second interval, and handle the Tick event.
Set up a class level DateTime variable called targetTime.
When you start the countdown, set targetTime to the current date and time plus the interval you want:
targetTime = DateTIme.Now.AddSeconds(30)
And start the Timer.
In the Tick event handler, display the difference:
Dim interval As Integer = (targetTime - DateTime.Now).TotalSeconds

If interval <= 0 Then
    interval = 0
End If

timerDisplay.Text = interval.ToString()
