Displaying the operating mode according to the day of the week?

Question

JavaScript

Hello. Please tell me the code with which you can display in the top-header block, the operating mode according to the day of the week.

For example, our hours of operation are Monday to Friday from 10:00 to 19:00. When you enter the site on one of these days, there will be a text - Today we work from 10 to 19 hours.

What script is needed, or can it be implemented through a function? Or even better, by adding data to the file responsible for the top header block on the site, or header.php for example.

For example, there is such an option, but it simply displays the current date.

Day today: <?php echo date('l, j F Y'); ?>

Answer 1

$('класс ссылки').on('click', function(event){
  event.preventDefault();
  var $el = $(event.currentTarget),
    img = $el.data('target');

  // stop slides
  // fire fancybox
});

$working_hours = [
  '1' => '10:00 — 19:00', // понедельник
  '2' => '10:00 — 19:00',
  '3' => '10:00 — 19:00',
  '4' => '10:00 — 19:00',
  '5' => '10:00 — 20:00', // пятница
  '6' => '10:00 — 15:00', // суббота
  '7' => __( 'Day off', 'textdomain' ) // воскресенье
];

$current_day = date( 'N' );

echo strtr( $current_day, $working_hours );
