Check If Post Was Published More Than 6 Months Ago Using get_the_date

Inside my content-single template, I have a conditional check that displays text based on how old the post is. The idea is to inform visitors that they might be reading “old” news.

Problem is; the 6+ months old text is displayed on posts that are only days old, and I do not understand why.

This is the code I am using:

<?php
    
    if ( strtotime( get_the_date() ) < strtotime( '-1 year' ) ) { ?>

        <span class="old-post"> 6+ months old </span>&nbsp;/&nbsp;
        
        <?php 
    } 

?>

This is the format I am using in WP admin for date and time:

l the jS of F @ H:i

Please help me understand how to fix this.

Method 1

The problem is that your date format is not a standard format that strtotime() understands. Instead just use get_the_date() with the format set to 'U', which returns the timestamp, and compare that to strtotime( '-1 year' ):

if ( get_the_date( 'U' ) < strtotime( '-1 year' ) ) {

}

Method 2

By using below code, you can check if Post Was published more than 6 Months ago using get_the_date.

place below code inside content-single template, It inform visitors that they are reading “old” news which is plublished 6+ months old.

# get last 6 month date from current date
$last_sixth_month_date = strtotime("-6 month"); 

# publish date
$post_poblish_date = strtotime( get_the_date() );

# get difference from two dates
$year1 = date('Y', $last_sixth_month_date);
$year2 = date('Y', $post_poblish_date);
$month1 = date('m', $last_sixth_month_date);
$month2 = date('m', $post_poblish_date);
$month_diffrence = (($year2 - $year1) * 12) + ($month2 - $month1);

if($month_diffrence < 0 )
{
    # check difference between date is 6 or more than 6
    if(abs($month_diffrence) >= 6 )
    {
        echo  '<span class="old-post"> 6+ months old </span>&nbsp;/&nbsp';
    }
}
