title: Rufus Scheduler: How to specify "on the first day of the month, at 8:00am"?
body: <p>I am trying to configure a schedule that uses the <a href="https://github.com/jmettraux/rufus-scheduler" rel="nofollow">rufus-scheduler gem</a>. I want to create a "once per month" schedule that runs at a specific time. I am trying to use the <code>every</code> syntax for defining it. How can I write this configuration so that it runs every month, on the first day, at 8:00am?</p>
