title: Tumblr blog: how to add a list of all posts sorted by dates
body: <p>I'm customizing a Tumblr blog and I cannot find a good way to access all the posts by date. 
  Tumblr allows you to display a particular post from a day using their <a href="http://www.tumblr.com/docs/en/custom_themes#day-pages" rel="nofollow">Day Pages</a>, but I want to find all posts and their dates, and then display them as a list sub-divided by months and years (really, it's like Wordpress's default sidebar). See example image here: <a href="http://i.stack.imgur.com/28gGH.png" rel="nofollow">http://i.stack.imgur.com/28gGH.png</a></p>
  
  <p>I've been looking through Tumblr's <a href="http://www.tumblr.com/docs/en/custom_themes" rel="nofollow">Custom Theme Documentation</a> but have not found a way to generate this information. Perhaps they offer it through their API? I haven't found anything yet.</p>
  
  <p>I appreciate any direction here. Thanks.</p>
