Building a business hours with javascript

I been trying to display "Currently opened on Monday - Friday." & going to change to "Currently closed on Saturday - Sunday."

I try to learned by googling but I was not able to achieve:

window.onload = function status() {
    var date = new Date();
    console.log(date);
  //var day  = date.getDay();
    var hour = date.getHours();// 0 = 12am, 1 = 1am, ... 18 = 6pm\
    console.log(hour);

   // check if it's between 9am and 11pm
   if(hour > 12 ) {
      document.getElementById('example').innerHTML = "Currently opened on Monday - Friday.";
    } else if (hour < 23 ) {
      document.getElementById('example').innerHTML = "Currently closed on Saturday - Sunday.";
    } else {
      console.log('Today is not a weekend and hour is between 12 - 23')
    }
  };

setInterval(status, 1000);
console.log(status);

you can use the getDay() method of the Date object to get the day of the week, then you check if it is a day of the week where its opened or not, if its opened then you check the hours.

function status() {
  var date = new Date();
  var day = date.getDay();
  var hour = date.getHours();
  //check if its sunday or saturday
  if (day == 0 || day == 6) {
    document.getElementById('example').innerHTML = "Currently closed on Saturday - Sunday.";
  // check if its between 9am and 11pm (inclusive)
  } else if (hour >= 9 && hour <= 23) {
    document.getElementById('example').innerHTML = "Currently opened on Monday - Friday.";
  } else {
    console.log('Today is not a weekend and hour is between 12 - 23')
  }
}

Here is a simple solution that could help to point you in the right direction.

I think that one of the problems with your code is that it only captured the hour of the day, and not the day of the week.

Below you can set your open days and hours in the open object, but if you have different open times on different days in the future, you will need to define the open object differently and will have to change how the getStatus function works

// set up the interval so that the time can be started and stopped as needed
    var interval;

// set the days and times when open (this could be set up differently, for example it could be a range instead)
    var open = {
        days: [1, 2, 3, 4, 5],
        hours: [12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23]
    }

// given a date, return a message determining if open
    var getStatus = function(currentDate){
        var hour = currentDate.getHours();
        var day = currentDate.getDay();
        var nowIsOpenDay = open.days.indexOf(day) > -1;
        var nowIsOpenHour = open.hours.indexOf(hour) > -1;

        var message = (nowIsOpenDay && nowIsOpenHour) ? 'Currently opened' : 'Currently closed';

        return {
            'message': message,
            'dateInfo': {
                'hour': hour,
                'day': day,
                'nowIsOpenDay': nowIsOpenDay,
                'nowIsOpenHour': nowIsOpenHour
            }
        }

    }

// run the timer and get the current status
    var startInterval = function(updateInterval){
        updateInterval = (typeof updateInterval === 'undefined') ? 1000 : updateInterval;
        interval = setInterval(function(){
            var currentStatus = getStatus(new Date());
            console.log(currentStatus.message)
            console.log(currentStatus.dateInfo.hour, currentStatus.dateInfo.day)
        }, updateInterval);
    }

// optionall stop the interval
    var stopInterval = function(){
        clearInterval(interval);
    }

// start
    startInterval(2000);
