Show Last modified date manually in WordPress

Note: Customizing your WordPress theme involves editing it’s different files which may need a little expertise with WordPress coding standard and development. It’s always better to backup your theme before editing. The recommended way to customize your theme is to do it locally (i.e. on a local WordPress installation rather than on your live site).

In order to show the modified date instead of the post published date, you need to edit some of your theme files. So, lets start, if you want to show the last updated date in your single (or full) post, just edit the single.php and look for the <?php the_date(); ?> or <?php get_the_date(); >.

If you’re not able to find the two functions, look for the template that has been called in the file to execute the loop. Try to figure out where these two functions are executing and replace it with the below code:

<?php the_modified_date('l, F j, Y', '<div class="the-modified-date">', '</div>'); >

The first parameter (highlighted in red) in the above function is the format of our date. That value there will display our date in this fashion: Sunday, May 12, 2013. Read more about Formatting WordPress date and time.

Value of the next parameter (highlighted in green) would be text or markup that should appear in the starting of our date. In the example code, I’ve added an opened HTML division tag since I wanted to put the date in a division.

Similarly, the next parameter (highlighted in blue) will carry value that should appear after the date. I’ve added a closing HTML div since I’ve placed and opened div tag in the start of the date. Check out the output I obtained by making the changes.
