Title: Archive Not Returning Correct Date Variable

  (Asked by: username_0 on 2018-01-04)
  
  I'm using the technique for creating an archive that's in the Craft docs: <https://craftcms.com/support/entry-archive>
  
  I'm archiving by day, so my code looks like this:
  
  ```
  {% set agendaEntries = craft.entries.section('agenda').status('live,pending,expired').limit(null) %}
  
  {% for day, entriesInDay in agendaEntries | group('postDate.day') %}
    <h2>{{ day | date('Y-m-d') }}</h2>
  
    <ul>
      {% for entry in entriesInDay %}
         <li>
            {# entry data #}
         </li>
      {% endfor %}
    </ul>
  {% endfor %}
  
  ```
  
  The looping and grouping (heh) works great, but the `{{ day }}` variable doesn't correctly output the date, instead I get the day-before-Epoch date (1969-12-31).
  
  I don't really understand how the `for` loop even knows what the `day` variable is, so I don't know how to troubleshoot.

  Your `postDate.day` will output the number of the day in the month so if your entries `postdate` is 02.dd.yyyy your output is `2`. Your array index will be something like `[2, 3, 5, 12, 31]` thus these values will be converted from the timestamp into a readable day with`<h2>{{ day | date('Y-m-d') }}</h2>`. The first timestamp (0) is `01.01.1970` because of your timezone you'll see only values around this date since you convert all the day numbers from 1-31 as timestamps to your given format.
  
  In case you did not know: the `day` variable represents only the keys of the array and with `| group('postDate.day')` you define the keys. I think your goal is to have keys like `[ 'Monday', 'Tuesday'.... 'Sunday']`. Your filter will look like:
  
  ```
  {% for day, entriesInDay in agendaEntries | group('postDate|date('l')') %}
  
  ```
