title: Schedule using time in tkinter
body: <p>I am very new to tkinter and I need some help coding it. So, I am trying to code a type of schedule in tkinter where if the current day is a specified day (for example, Sunday) and if the current time on that day is in between 2 times, then a messagebox pops up. For example, if it is Monday and the current time is in between 11:30 and 12:00, then a message box saying, &quot;Eat lunch!&quot; pops up.</p>
  <p>I have been able to code an incomplete version of this on python, but I don't know how to add the current day part and the in between 2 times part and how to apply this to tkinter.</p>
