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
