title: how can I make sure a day is a weekday in Rails?
body: <p>I have a message substitution called next_week which basically takes Date.today + 7.days.</p>
  
  <p>However, although I still want to send emails on weekends, if the next_week falls on a weekend, I want it to know this and push to the Monday.</p>
  
  <p>How do i do this?</p>
