I often update my older posts with additional information to keep them fresh and accurate. I include both the “Published” date and “Last Updated” date at the top of posts so users know the history and accuracy of the article.
The WordPress function
get_the_modified_date() can be used to list this date, but there’s one small problem. It changes for any update, no matter how minor.
If I’m fixing a typo or adjusting the categories on the post, I don’t want the modified date to change. So I built a plugin.
Limit Modified Date
This plugin works with both the Gutenberg block editor and classic editor.
This plugin adds a checkbox to the Publish box that lets you prevent the modified date from updating. Leave this checked while you’re making your minor content changes.
When it’s time for a notable content update, uncheck the box and save the post.
Whether you’re using the Classic Editor or the new Gutenberg block editor, this plugin will work great for you.
