<?php

$date_string = get_field( 'person-birthday', $post->ID ); 

if( $date_string ) {
    // Convert to DateTime object
    $birthday = DateTime::createFromFormat( 'Ymd', $date_string ); 

    if( $birthday ) {
        // Calculate age
        $interval = $birthday->diff( new DateTime() ); 

        // Display formatted date + age
        echo $birthday->format('d M Y') . ' (' . $interval->y . ' ans)';
