You mentioned when you loaded the .php file directly, does this mean this isn’t a part of a WordPress page? A stand-alone PHP page? I’m not sure whether ACF fields would be accessible through this or not, i’d guess not.

You’d be better off adding a php callback function for your ajax in your functions.php file.

Here’s a simple example of getting a field with AJAX:

In your functions.php:

add_action('wp_ajax_getdatefunction', 'getdate'); 
add_action('wp_ajax_nopriv_getdatefunction', 'getdate'); 
function getdate(){

   the_field('your_date_field');

   die();
}

In your JS file:

$('button').click(function(){
	$.ajax({
		type: "POST", 
		url:'/wp-admin/admin-ajax.php',
		data: 'action=getdatefunction',
		cache: true, 
		success: function(results){
			$('.your-date-container').html(results);
                        alert('The date is: '+results);
		}
	});
});
