Message in Holidays

[Alexisback]

How to view a message for each holiday? example for test: '10/03' => array ('9:00-23:59','Merry X-mas')

I tried so but it doesn't work

/ OPTIONAL
    // Add exceptions (great for holidays etc.)
    // MUST be in a format month/day[/year] or [year-]month-day
    // Do not include the year if the exception repeats annually
    $exceptions = array(
        '2/24'  => array('11:00-18:00'),
        '10/18' => array('11:00-16:00', '18:00-20:30'),
        '10/03' => array ('9:00-23:59','Merry X-mas')
    );
