WordPress Relative Date

Instead of displaying the date that your post was posted, you can make it relative – “6 months ago” or “3 weeks ago” or whatever. Use this in your posts/comments/pages

 # For posts &amp; pages #
<?php echo human_time_diff(get_the_time('U'), current_time('timestamp')) . ' ago'; 
# For comments #
<?php echo human_time_diff(get_comment_time('U'), current_time('timestamp')) . ' ago'; ?>
