(this only works for desktop computers, NOT smartphones or mobile devices. On a mobile phone, you can just keep scrolling down and looking through the posts, and click the arrow at the bottom to continue on, as shown here..
For Desktop or Laptop computers.....
First you scroll down and on the Left side, under the "Archives"..... you click on the Archived Day you are looking for ...
Once you have selected a day, you can scroll through that days posts. And if you get to the bottom of scrolling through that day and you haven't seen the post you are looking for yet….you click on the ">Older" link on the right side underneath the Archives.
That will take you back another 10-20 posts or so…and you can keep clicking the "<Older" link, until you find the post you are looking for in that Archived Day….
