title: calendar day view logic
body: <p>I don't know if my logic is right, but I'm trying to implement the calendar day view from scratch. And for implementing the sharing of same space with the same time, its kinda tricky for me.</p>
  
  <p>I have a list of time:</p>
  
  <p>A. 1am - 2am</p>
  
  <p>B. 1am - 2.30am</p>
  
  <p>C. 1.30am - 3am</p>
  
  <p>So basically A-C have a common time of 2am, so they need to share in the same space. So how can do the logic of that?</p>
