How to display the day of publication?

You can use something like

{{#formatDate}} DD {{/formatDate}}

for day of the month. The documentation for date formats is in the Template developer guide at the bottom of the reference.

This is great to learn about. I'd never dived into the details of the {{all_entries}} vs. {{archives}}. I've used the info to update my archives page, only providing a break out of year. The code I'm using is below, but I'm struggling with one bit (which may not even be possible).

How would I provide the count of posts within the year? I've attempted various things, but my hunch is that the way the array is structured is making it troublesome.

To provide the number of posts within the year, you can simply do this:

{{#archives}}
       <h2>{{year}} - {{entries.length}} posts</h2>
             ...
```			 

Thank you. I did try this before, but implemented exactly as you described and get the same behavior. No post count shows up.

<h2>Posts ({{all_entries.length}})</h2>
       {{#archives}}
       <h2>{{year}} ({{entries.length}})</h2>
        {{#months}}
       {{#entries}}
       <div class="row">
            <div class="column left">          		
                  <a href="{{{url}}}">{{title}}
                      {{#tagged.linkpost}}
          			&#x21FE;
          			{{/tagged.linkpost}}
                  </a>
            </div>
              <div class="column right">
                  <span class="smalldate">{{date}}</span>
            </div>
        </div>
        {{/entries}}
        {{/months}}
        {{/archives}}

Sorry, that was a case of me expecting a feature to exist which does not actually exist. I have just made this work:

       <h2>{{year}} - {{total}} post{{s}}</h2>

This is now documented in the developer reference

Thanks, David. Truly appreciate the efforts and the pluralization token is just... <chef's kiss>

Many and great thanks for the answer to the original question and important link to the Developers Guide - excellent!
