title: Django - iterate number in for loop of a template
body: <p>I have the following for loop in my django template displaying days. I wonder, whether it's possible to iterate a number (in the below case i) in a loop. Or do I have to store it in the database and then query it in form of days.day_number?</p>
  
  <pre><code>{% for days in days_list %}
      &lt;h2&gt;# Day {{ i }} - From {{ days.from_location }} to {{ days.to_location }}&lt;/h2&gt;
  {% endfor %}
  </code></pre>
