title: Why React Big Calendar does not display events?
body: <p>I've followed a documentation and uploaded a project <a href="https://codesandbox.io/s/yq0jr5mp0z" rel="nofollow noreferrer">here</a>.</p>
  
  <p>There are no errors, but events are not displayed. Here's some code:</p>
  
  <pre><code>&lt;BigCalendar
    events={events}
    startAccessor='startDate'
    endAccessor='endDate'
    defaultDate={new Date(2017, 11, 1)}
    views={allViews}
    defaultView='day'
    titleAccessor='tttttttt'
    components={{
      event: Event,
      agenda: {
        event: EventAgenda
      }
    }}
  /&gt;
  </code></pre>
  
  <p>Cannot understand what is the problem. According to this <a href="https://stackoverflow.com/questions/47710223/basic-setup-of-react-big-calendar-events-not-showing">answer</a> I added some style, but the result is the same.
