				if(Validation.get('IsEmpty').test(v)) return true;
				var regex = /^(\d{2})\-(\d{2})\-(\d{4})$/;
				if(!regex.test(v)) return false;
				var d = new Date(v.replace(regex, '$2/$1/$3'));
				return ( parseInt(RegExp.$2, 10) == (1+d.getMonth()) ) && 
							(parseInt(RegExp.$1, 10) == d.getDate()) &&
