Right now I am using the code below to post a message between 12 and 1.

How would I post the same message but only for the times of 12:00pm to 12:15pm as same Monday - Friday?

Tried several things using timers but it isn't working. Thanks in advance!...
Dim now As DateTime = DateTime.Now
        If Not (now.DayOfWeek = DayOfWeek.Saturday Or now.DayOfWeek = DayOfWeek.Sunday) Then
            If now.Hour = 12 Then
                lblMessage.Text = "Lunch Time"
            Else
                lblMessage.Text = String.Empty
            End If
        End If

Try something like this:
Public Class Form1
 
    Private LunchTimeSpanStart As New TimeSpan(12, 0, 0)
    Private LunchTimeSpanEnd As New TimeSpan(12, 15, 0)
 
    Private WithEvents tmr As System.Windows.Forms.Timer
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        tmr = New System.Windows.Forms.Timer
        tmr.Interval = 1000
        tmr.Start()
    End Sub
 
    Private Sub tmr_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles tmr.Tick
        Select Case DateTime.Now.DayOfWeek
            Case DayOfWeek.Sunday, DayOfWeek.Saturday
                lblMessage.Text = String.Empty
 
            Case Else
                Dim dtNow As DateTime = DateTime.Now
                Dim LunchDateTimeStart As DateTime = DateTime.Today.Add(LunchTimeSpanStart)
                Dim LunchDateTimeEnd As DateTime = DateTime.Today.Add(LunchTimeSpanEnd)
                If dtNow >= LunchDateTimeStart AndAlso dtNow <= LunchDateTimeEnd Then
                    lblMessage.Text = "Lunch Time"
                Else
                    lblMessage.Text = String.Empty
                End If
        End Select
    End Sub
 
End Class
