Replace Date Format

I prefer to have my dates in human-readable time difference or AP style dates, so this function will replace the default date format and output either the human-readable time difference or if the date difference is more than 180 days, the AP Style date.

function format_date_in_ap_style($date_string, $d = '', $post = null) {
    $post = get_post($post);
    
    if (!$post) {
        return $date_string;
    }

    // Get timestamp based on current filter
    if ('get_the_modified_date' === current_filter()) {
        $timestamp = strtotime($post->post_modified);
    } else {
        $timestamp = strtotime($post->post_date);
    }

    // Get the difference in days
    $days_difference = (current_time('timestamp') - $timestamp) / DAY_IN_SECONDS;

    if ($days_difference <= 180) {
        // Get human-readable time difference
        return human_time_diff($timestamp, current_time('timestamp')) . ' ago';
    } else {
        // Get the date in AP style
        $ap_month_format = array(
            'January' => 'Jan.', 'February' => 'Feb.', 'March' => 'March', 'April' => 'April',
            'May' => 'May', 'June' => 'June', 'July' => 'July', 'August' => 'Aug.',
            'September' => 'Sept.', 'October' => 'Oct.', 'November' => 'Nov.', 'December' => 'Dec.'
        );

        $month_name = $ap_month_format[date("F", $timestamp)];
        $day = date("j", $timestamp);
        $year = date("Y", $timestamp);

        return $month_name . ' ' . $day . ', ' . $year;
    }
}

add_filter('get_the_date', 'format_date_in_ap_style', 10, 3);
add_filter('get_the_modified_date', 'format_date_in_ap_style', 10, 3);
