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

Question

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

Strother

Don't waste your time https://mcmap.net/q/37345/-how-do-you-display-javascript-datetime-in-12-hour-am-pm-format its working.. – Garget

@Garget WARNING: toLocaleTimeString() may behave differently based on region / location. Measure twice, cut once. – Malpractice

@AbandonedCart is that actually a saying? – Cavendish

Answer 1

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 2

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

What about hour, minutes, and AM/PM? – Fret

As of Feb 2018 its working just fine on chrome Neolisk - developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/… – Doth

it should return 07:23, IMO – Sharl

@HumbleDolt You might be confusing 'numeric' with '2-digit'. – Ardehs

@Katie in 2019 too – Trott

Source: caniuse.com/#search=toLocaleString() - "...supported in effectively all browsers (since IE6+, Firefox 2+, Chrome 1+ etc)" – Cp

this is the best answer but how do you change the capitalization of AM/PM – Erwin

Great answer! Here's a link to the MDN docs for information on the options if anyone needs it: Intl.DateTimeFormat() – Herbart

@Ardehs hour: '2-digit', minute: '2-digit' – Ambulate

Answer 3

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.

People don't use Regex enough. This worked for me without adding the jquery/microsoftajax library suggestions above. – Pileup

What would be the regex be to have a trailing zero at the beginning of the hour if it was a single digit. Say in your first example of 8:12 PM it would be 08:12 PM? – Segmental

@404 it's the same, ([\d]+:[\d]{2}) is the part we are interested in. Use the colon (:) as the separator and we see the first part is [\d]+. The plus means one or more. So it's looking for one or more digit (including zero. If you had to guarantee a zero is there, it would be (0[\d]:[\d]{2}). This now reads, look for 0 plus one other digit, then colon, then the rest. – Kilian

console.log(new Date().toLocaleTimeString().replace(/([\d]+:[\d]{2})(:[\d]{2})(.*)/, "$1$3")); To get current time – Corrales

Doesn't work in Australia. new Date('7/10/2013 20:12:34').toLocaleTimeString() gives 20:12:34, and regex just gave 20:12. @abhay-kumar answer time.toLocaleString('en-US', { hour: 'numeric', minute: 'numeric', hour12: true }) worked. – Alba

Answer 4

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.

Translator

@koolinc for midnight it shows 12. I'm not sure what else the desired behavior would be. – Translator

I stand corrected. In my country the 24-hour clock is used, so I'm not that familiar with the 12-hour clock. Indeed midnight is 12:00am. – Continuance

This method is perfect if need only hour in 12 hr format – Tagore

Answer 5

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.

Longlived

to use this, assign the new string to a variable eg: let result = new Intl.DateTi.... alert(result); – Palmy

Can also do: const time = new Date().toLocaleString([], { hour: 'numeric', minute: 'numeric' }); //"6:30 AM" – Especial

Answer 6

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?

Gaddis

This is the most simple answer. Vote up because is a javascript native solution. Thanks – Harter

This is a nice native solution. – Cocytus

Answer 7

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)

Simonne

This 12H format saved my day, thanks. – Athelstan

Answer 8

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

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

console.log(moment().format('hh:mm a'));

Updated for more compression

const formatAMPM = (date) => {
  let hours = date.getHours();
  let minutes = date.getMinutes();    
  const ampm = hours >= 12 ? 'pm' : 'am';

  hours %= 12;
  hours = hours || 12;    
  minutes = minutes < 10 ? `0${minutes}` : minutes;

  const strTime = `${hours}:${minutes} ${ampm}`;

  return strTime;
};

console.log(formatAMPM(new Date()));

Answer 10

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 11

Short RegExp for en-US:

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

Worst

this doesn´t work on latest safari and firefox browsers, time still uses 24 hour format – Juxon

answers get outdated as time goes by. Feel free to edit and update! – Worst

This actually will make the string look like 1:54 PM CDT. To remove the CDT alter your regex to the following .replace(/:\d+ |\CDT/g, ' '). Although, CDT is just my timezone. If you have a different timezone I suppose you would need to change to that zone code. – Ovotestis

The output of toLocaleTimeString is implementation dependent, so not reliably the same format everywhere. – Televise

Answer 12

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;

Pink

Should be less than or equal to for hour calculation else noon shows up as 0. So: var hour = (d.getHours() <= 12). Still has issue with midnight so you have to check if zero then set to 12 too. – Alee

Answer 13

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

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);
        result = hour;

        if(hour < 10){

Answer 15

Hopefully this answer is a little more readable than the other answers (especially for new comers).

Here's the solution I've implemented in some of my sites for informing the last time the site code was modified. It implements AM/PM time through the options parameter of date.toLocaleDateString (see related Mozilla documentation).

// Last time page code was updated/changed
const options = {
    year: "numeric",
    month: "long",
    weekday: "long",
    day: "numeric",
    hour: "numeric",
    minute: "numeric",
    second: "numeric",
    hour12: true // This is the line of code we care about here
    /*
        false: displays 24hs format for time
        true: displays 12, AM and PM format
    */
};

let last = document.lastModified;
let date = new Date(last);
let local = date.toLocaleDateString("en-US", options);
let fullDate = `${local}`;
document.getElementById("updated").textContent = fullDate;

Which output is in the format:

Saturday, May 28, 2022, 8:38:50 PM

This output is then displayed in the following HTML code:

<p>Last update: <span id="updated">_update_date_goes_here</span></p>

NOTE: In this use case, document.lastModified has some weird behaviors depending if it's run locally or on a external server (see this Stack Overflow question). Though it works correctly when I run it in my GitHub page (you should see it in action in the site at the footer).

Answer 16

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.

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

        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 -->

Answer 19

If you have time as string like so var myTime = "15:30", then you can use the following code to get am pm.

var hour = parseInt(myTime.split(":")[0]) % 12;
var timeInAmPm = (hour == 0 ? "12": hour ) + ":" + myTime.split(":")[1] + " " + (parseInt(parseInt(myTime.split(":")[0]) / 12) < 1 ? "am" : "pm");

Answer 20

If anyone is looking for a 1-liner:

const formatAMPM = date => `${(date.getHours() % 12) || 12}:${date.getMinutes().toString().padStart(2, '0')} ${date.getHours() < 12 ? 'AM' : 'PM'}`    

OR more readable 3-liner (or if you don't have padStart in your browser):

const formatAMPM = (date) => {
  let minutes = date.getMinutes()
  minutes = minutes < 10 ? '0' + minutes : minutes
  return `${(date.getHours() % 12) || 12}:${minutes} ${date.getHours() < 12 ? 'AM' : 'PM'}`

This is incorrect. The hours could be greater than 12. – Patterman

When 12.00 pm the var ampm will be "pm". So 12.00 PM to 11.00 PM hours will be 12 to 23 that store "pm" value and for others, var ampm will store "am" value. Hope you understand. – Varicotomy

Hi Juyel ! Indeed when the hours is greater than 12, the value would be PM. But the question is "How do you display JavaScript datetime in 12 hour AM/PM format?" - you need to help OP convert the entire time to the AM/PM format. For example, 14:30 would be 2:30 PM. – Patterman

This is the easiest Way you can Achieve this using ternary operator or you can also use if else instead !

const d = new Date();
let hrs = d.getHours();

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 34

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';
};
