I think you need to add the start_time alias definition inside the model you use for your events, here I have this inside my app/models/evento.rb

def start_time
  self.fecha
end

Here 'fecha' is the start date for my event. Then you have to manipulate your events as Carlos Ramirez explains, so you have to have something like this inside your 'calendar.html.erb':

<h3>Eventos (<%= @eventos.count %>)</h3>
<%= month_calendar events: @eventos do |date, eventos| %>
  <%= date.day %>
  <% eventos.each do |evento| %>
    <div>
      <%= link_to evento.title, evento %>
    </div>
  <% end %>
<% end %>

That should render the link to your event.

Copied files from https://github.com/excid3/simple_calendar/tree/master/lib directory into my applications lib directory

edited my calendar.html.erb file 

<%= month_calendar do |date| %>
<%= date %>
<% end %>

Restarted server and got a calendar displaying

As per the documentation, the calendar helper takes a parameter which is a Hash. In your code snippet you've passed in a collection of events (@events), not a Hash of options.

If you want to pass the events in, the documentation shows how to do it. 

<%= month_calendar events: @meetings do |date, meetings| %>
  <%= date %>

  <% meetings.each do |meeting| %>
    <div>
      <%= meeting.name %>
    </div>
  <% end %>
<% end %>

Source: https://github.com/excid3/simple_calendar#rendering-events

So in your case, you'll want to pass your @events collection in as a key value pair like so: <%= calendar events: @events do %>.
