php - Wordpress shortcode to display post date +1 day

I'm trying to create a shortcode that will display the post date +1 day. Example: if the post was published on the 3rd I want a shortcode that will display 4th. I've tried the following but not getting the results I want.

// [nextday]  
function displaydate_next(){  
    return the_time('jS', strtotime('+1 day')); 
}  
add_shortcode('nextday', 'displaydate_next'); 
// end nextday date

Solution:

I think you also need to get the month and year so it can calculate the next day. The below is what you need:

// [nextday]  
function displaydate_next(){  

$time = get_the_time('jS F, Y');
$date = strtotime(date("jS F, Y", strtotime($time)) . " +1 day");
return date('jS', $date); 

}  
add_shortcode('nextday', 'displaydate_next'); 
// end nextday date

Answer

Solution:

You can use WP Date and Time Shortcode for the purpose. Just adddays="+1" as an attribute.

For example:[wp-dt item="custom" format="jS" days="+1"].
