How can I add value in Django 2 template

Scenario:I want to make a page for available slots for booking ,for which I want print time slot for 1 hour that is from i To i+1 and color it according to the availability. I am newbie to django and can't figure out the way to make a calendar and that is why I am printing time values in HTML template. Is there any other way to make this page and also is printing 'i+1' possible.

Views.py

@login_required
def slots(request):
    k={  'pro':range(8,17)
    }
    return render(request, 'login/slots.html',k)

slots.html

{% for i in pro %}
          <tr>  
           <td>1</td>
            <td>2</td>
            <td>3</td>
            <td>4</td>
            <td id="demo">{{ i }} to {{ i+1 }}</td>
          </tr>
          {% endfor %}

I know this might be a silly question but I am not able to figure it out, any help is appreciated.

There is a built-in filter in Django template called add. You can add something to a value in templates using {{ value|add:"2" }}.

In this case specifically, try: 

<td id="demo">{{ i }} to {{ i|add:"1" }}</td>
