Oh so you wanna conditionally output some day/month/time-related shit in JS without using a library? This is some wack shit you could use. Could be good if you are making a website for a shop that has no back-end logic for open/close times.

getDate

getDate: {
  init: function() {
    var dateContainer = document.getElementById('date'),
        today = new Date(),
        dayNames= ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'],
        monthNames = ['January', 'February', 'March', 'April', 'May', 'June','July', 'August', 'September', 'October', 'November', 'December'],
        dayText = dayNames[today.getDay()],
        monthText = monthNames[today.getMonth()],
        dateText = today.getDate(),
        weekday = today.getDay();
        
    if ([3,4,5,6].indexOf(weekday) > -1) {
      var hours = '12-7PM';
    } else if (weekday === 0) {
      var hours = '12-5PM';
    } else {
      var hours = 'closed';
    }
    
    // outputs something like TUESDAY, NOVEMBER 19, CLOSED
    dateContainer.innerHTML('' + dayText + ', ' + monthText + ' ' + dateText + ', ' + hours + '');
  };
};
