title: discord.py send message at a specific hour and date
body: <p>I'm working on a bot to facilitate some of the things we do on hand in my team. With that I started to create some tasks that are running well, I need to create a notification that will run from Monday to Friday at 16, I saw some blogs and I tried to apply only without success, today this is my code and the function I want to call is called &quot;LEMBRAR()&quot;, with that I wanted to know what options I have to be running this.</p>
  <pre><code>import discord
