title: Created by user period jobs Django
body: <p>I have a small website which plots Google Calendar data for registered user. I want to add a feature: user should be able to create mailing schedule (site will generate pictures and send them on email on chosen time).</p>
  
  <p><strong>Task:</strong> user should be able to create/modify periodic jobs. </p>
  
  <p><strong>Question:</strong> what is the best way to do this?</p>
  
  <p>I've checked Celery (brokers made me think it's too much for such a small project), things like <a href="http://django-cron.readthedocs.io/en/latest/installation.html" rel="nofollow noreferrer">django-cron</a> doesn't provide jobs created by user as far as I see.</p>
