How do you display JavaScript datetime in 12 hour AM/PM format?

How do you display a JavaScript datetime object in the 12 hour format (AM/PM)?

Answers:

Answer

function formatAMPM(date) {
  var hours = date.getHours();
  var minutes = date.getMinutes();
  var ampm = hours >= 12 ? 'pm' : 'am';
  hours = hours % 12;
  hours = hours ? hours : 12; // the hour '0' should be '12'
  minutes = minutes < 10 ? '0'+minutes : minutes;
  var strTime = hours + ':' + minutes + ' ' + ampm;
  return strTime;
}

console.log(formatAMPM(new Date));

Answer

If you just want to show the hours then..

var time = new Date();
console.log(
  time.toLocaleString('en-US', { hour: 'numeric', hour12: true })
);  

Output : 7 AM

If you wish to show the minutes as well then...

var time = new Date();
console.log(
  time.toLocaleString('en-US', { hour: 'numeric', minute: 'numeric', hour12: true })
);

Output : 7:23 AM

Answer

You can also consider using something like date.js:

<html>
<script type="text/javascript" src="http://www.datejs.com/build/date.js"></script>

<script>
   (function ()
   {
      document.write(new Date().toString("hh:mm tt"));
   })();
</script>
</html>

Answer

Here's a way using regex:

console.log(new Date('7/10/2013 20:12:34').toLocaleTimeString().replace(/([\d]+:[\d]{2})(:[\d]{2})(.*)/, "$1$3"))
console.log(new Date('7/10/2013 01:12:34').toLocaleTimeString().replace(/([\d]+:[\d]{2})(:[\d]{2})(.*)/, "$1$3"))

This creates 3 matching groups:

  • ([\d]+:[\d]{2}) - Hour:Minute
  • (:[\d]{2}) - Seconds
  • (.*) - the space and period (Period is the official name for AM/PM)

Then it displays the 1st and 3rd groups.

WARNING: toLocaleTimeString() may behave differently based on region / location.

Answer

If you don't need to print the am/pm, I found the following nice and concise:

var now = new Date();
var hours = now.getHours() % 12 || 12;  // 12h instead of 24h, with 12 instead of 0. 

This is based off @bbrame's answer.

Answer

As far as I know, the best way to achieve that without extensions and complex coding is like this:

     date.toLocaleString([], { hour12: true});

Javascript AM/PM Format

<!DOCTYPE html>
<html>
<body>
    <p>Click the button to display the date and time as a string.</p>

    <button onclick="myFunction()">Try it</button>
    <button onclick="fullDateTime()">Try it2</button>
    <p id="demo"></p>
    <p id="demo2"></p>
    <script>
        function myFunction() {
            var d = new Date();
            var n = d.toLocaleString([], { hour: '2-digit', minute: '2-digit' });
            document.getElementById("demo").innerHTML = n;
        }
        function fullDateTime() {
            var d = new Date();          
            var n = d.toLocaleString([], { hour12: true});
            document.getElementById("demo2").innerHTML = n;
        }
    </script>
</body>
</html>

I found this checking this question out.

How do I use .toLocaleTimeString() without displaying seconds?

Answer

My suggestion is use moment js for date and time operation.

https://momentjs.com/docs/#/displaying/format/

console.log(moment().format('hh:mm a'));
<script src="//cdnjs.cloudflare.com/ajax/libs/moment.js/2.17.1/moment.min.js"></script>

Answer

use dateObj.toLocaleString([locales[, options]])

Option 1 - Using locales

var date = new Date();
console.log(date.toLocaleString('en-US'));

Option 2 - Using options

var options = { hour12: true };
console.log(date.toLocaleString('en-GB', options));

Note: supported on all browsers but safari atm

Answer

Please find the solution below

var d = new Date();
var amOrPm = (d.getHours() < 12) ? "AM" : "PM";
var hour = (d.getHours() < 12) ? d.getHours() : d.getHours() - 12;
return   d.getDate() + ' / ' + d.getMonth() + ' / ' + d.getFullYear() + ' ' + hour + ':' + d.getMinutes() + ' ' + amOrPm;
Answer

Short RegExp for en-US:

var d = new Date();
d = d.toLocaleTimeString().replace(/:\d+ /, ' '); // current time, e.g. "1:54 PM"
Answer

Check out Datejs. Their built in formatters can do this: http://code.google.com/p/datejs/wiki/APIDocumentation#toString

It's a really handy library, especially if you are planning on doing other things with date objects.

Answer

I fount it's here it working fine.

var date_format = '12'; /* FORMAT CAN BE 12 hour (12) OR 24 hour (24)*/


var d       = new Date();
var hour    = d.getHours();  /* Returns the hour (from 0-23) */
var minutes     = d.getMinutes();  /* Returns the minutes (from 0-59) */
var result  = hour;
var ext     = '';

if(date_format == '12'){
    if(hour > 12){
        ext = 'PM';
        hour = (hour - 12);

        if(hour < 10){
            result = "0" + hour;
        }else if(hour == 12){
            hour = "00";
            ext = 'AM';
        }
    }
    else if(hour < 12){
        result = ((hour < 10) ? "0" + hour : hour);
        ext = 'AM';
    }else if(hour == 12){
        ext = 'PM';
    }
}

if(minutes < 10){
    minutes = "0" + minutes; 
}

result = result + ":" + minutes + ' ' + ext; 

console.log(result);

and plunker example here

Answer
<script>
var todayDate = new Date();
var getTodayDate = todayDate.getDate();
var getTodayMonth =  todayDate.getMonth()+1;
var getTodayFullYear = todayDate.getFullYear();
var getCurrentHours = todayDate.getHours();
var getCurrentMinutes = todayDate.getMinutes();
var getCurrentAmPm = getCurrentHours >= 12 ? 'PM' : 'AM';
getCurrentHours = getCurrentHours % 12;
getCurrentHours = getCurrentHours ? getCurrentHours : 12; 
getCurrentMinutes = getCurrentMinutes < 10 ? '0'+getCurrentMinutes : getCurrentMinutes;
var getCurrentDateTime = getTodayDate + '-' + getTodayMonth + '-' + getTodayFullYear + ' ' + getCurrentHours + ':' + getCurrentMinutes + ' ' + getCurrentAmPm;
alert(getCurrentDateTime);
</script>
Answer

Use Moment.js for this

Use below codes in JavaScript when using moment.js

H, HH       24 hour time
h, or hh    12 hour time (use in conjunction with a or A)

The format() method returns the date in specific format.

moment(new Date()).format("YYYY-MM-DD HH:mm"); // 24H clock
moment(new Date()).format("YYYY-MM-DD hh:mm A"); // 12H clock (AM/PM)
moment(new Date()).format("YYYY-MM-DD hh:mm a"); // 12H clock (am/pm)
Answer

In modern browsers, use Intl.DateTimeFormat and force 12hr format with options:

    let now = new Date();

    new Intl.DateTimeFormat('default',
        {
            hour12: true,
            hour: 'numeric',
            minute: 'numeric'
        }).format(now);

    // 6:30 AM

Using default will honor browser's default locale if you add more options, yet will still output 12hr format.

Here is another way that is simple, and very effective:

        var d = new Date();

        var weekday = new Array(7);
        weekday[0] = "Sunday";
        weekday[1] = "Monday";
        weekday[2] = "Tuesday";
        weekday[3] = "Wednesday";
        weekday[4] = "Thursday";
        weekday[5] = "Friday";
        weekday[6] = "Saturday";

        var month = new Array(11);
        month[0] = "January";
        month[1] = "February";
        month[2] = "March";
        month[3] = "April";
        month[4] = "May";
        month[5] = "June";
        month[6] = "July";
        month[7] = "August";
        month[8] = "September";
        month[9] = "October";
        month[10] = "November";
        month[11] = "December";

        var t = d.toLocaleTimeString().replace(/:\d+ /, ' ');

        document.write(weekday[d.getDay()] + ',' + " " + month[d.getMonth()] + " " + d.getDate() + ',' + " " + d.getFullYear() + '<br>' + d.toLocaleTimeString());

    </script></div><!-- #time -->

Or just simply do the following code:

    <script>
        time = function() {
            var today = new Date();
            var h = today.getHours();
            var m = today.getMinutes();
            var s = today.getSeconds();
            m = checkTime(m);
            s = checkTime(s);
            document.getElementById('txt_clock').innerHTML = h + ":" + m + ":" + s;     
            var t = setTimeout(function(){time()}, 0);
        }

        time2 = function() {
            var today = new Date();
            var h = today.getHours();
            var m = today.getMinutes();
            var s = today.getSeconds();
            m = checkTime(m);
            s = checkTime(s);
            if (h>12) {
                document.getElementById('txt_clock_stan').innerHTML = h-12 + ":" + m + ":" + s;
            }               
            var t = setTimeout(function(){time2()}, 0);
        }

        time3 = function() {
            var today = new Date();
            var h = today.getHours();
            var m = today.getMinutes();
            var s = today.getSeconds();
            if (h>12) {
                document.getElementById('hour_line').style.width = h-12 + 'em'; 
            }
            document.getElementById('minute_line').style.width = m + 'em';  
            document.getElementById('second_line').style.width = s + 'em';  
            var t = setTimeout(function(){time3()}, 0);
        }

        checkTime = function(i) {
            if (i<10) {i = "0" + i};  // add zero in front of numbers < 10
            return i;
        }           
    </script>

Answer

A short and sweet implementation:

// returns date object in 12hr (AM/PM) format
var formatAMPM = function formatAMPM(d) {
    var h = d.getHours();
    return (h % 12 || 12)
        + ':' + d.getMinutes().toString().padStart(2, '0')
        + ' ' + (h < 12 ? 'A' : 'P') + 'M';
};
Answer

It will return the following format like

09:56 AM

appending zero in start for the hours as well if it is less than 10

Here it is using ES6 syntax

const getTimeAMPMFormat = (date) => {
  let hours = date.getHours();
  let minutes = date.getMinutes();
  const ampm = hours >= 12 ? 'PM' : 'AM';
  hours = hours % 12;
  hours = hours ? hours : 12; // the hour '0' should be '12'
  hours = hours < 10 ? '0' + hours : hours; // appending zero in the start if hours less than 10
  minutes = minutes < 10 ? '0' + minutes : minutes;
  return hours + ':' + minutes + ' ' + ampm;
};
console.log(getTimeAMPMFormat(new Date)); // 09:59 AM
