Do not know what i'm doing wrong and would like some help to fix it i am trying to make script to write out the day date and time like this It is currently: 3:15 PM on Wednesday, September 21. this is what i have
function renderTime(){
var mydate = new date();
var year = mydate.getYear();
if(year < 1000){
year +=1900
}
var day = mydate.getDay();
var month = mydate.getMonth();
var daym = mydate.getDate();
var dayarray = new Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday");
var montharray = new Array("Jannuary","Februry","March","April","May","June","July","Augest","September","October","November","December");
var currentTime = new Date();
var h = currentTime.getHour();
var m = currentTime.getMinutes();
var ampm = h >= 12 ? 'pm' : 'am';
if(h == 24){
h = 0;
} else if (h > 12 ){
h = h - 0;
}
if(h < 10){
h = "0" + h;
}
if(m < 10){
m = "0" + m;
}
}
document.write("It is currently"+h+m+"on"+dayarray[day]+ montharray[month]+daym);
You can simplify it by using toLocaleDateString and toLocaleTimeString:
var myDate = (new Date()).toLocaleDateString("en-US", {weekday: 'long',month: 'long',day: 'numeric'});
var myTime = (new Date()).toLocaleTimeString("en-US", {hour: 'numeric',minute: 'numeric'
});
var message = 'It is currently: ' + myTime + ' on ' + myDate;
console.log(message);
var mydate = new Date();
var year = mydate.getYear();
if(year < 1000){
year +=1900
}
var day = mydate.getDay();
var month = mydate.getMonth();
var daym = mydate.getDate();
var dayarray = new Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday");
var montharray = new Array("Jannuary","Februry","March","April","May","June","July","Augest","September","October","November","December");
var currentTime = new Date();
var h = currentTime.getHours();
var m = currentTime.getMinutes();
var ampm = h >= 12 ? 'pm' : 'am';
if(h == 24){
h = 0;
} else if (h > 12 ){
h = h - 12;
}
if(h < 10){
h = "0" + h;
}
if(m < 10){
m = "0" + m;
}
document.write("It is currently "+h+ ":"+ m+ ampm +" on "+dayarray[day] + ' ' + montharray[month] + ' '+daym);
let dateString = new Date().toLocaleDateString("en-US").split("/");
// returns an array ["month", "day as number in month", "year"]
let timeString = new Date().toLocaleTimeString("en-US").split(/:| /);
// returns an array ["hour", "minute", "second", "am or pm"]
let weekDayNumber = new Date().getDay();
let days = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"];
let months = ["Jannuary","Februry","March","April","May","June","July","Augest","September","October","November","December"];
document.write("It is currently"+timeString[0]+timeString[1]+"on"+days[weekDayNumber ]+ months[dateString[0]]+dateString[1]);
You're running all your date rendering in a function which keeps all your interim variables private. This is a good thing, but you're not providing any way to get the result out. Include a return statement in your function to return the formatted string like this:
return ("It is currently "+h+":"+m+" on "+dayarray[day]+" "+ montharray[month]+" "+daym);
You create a new Date object for time, but you should just use the one you created for date, and you missed a letter of a method name. Here's the revised version:
function renderTime(){
var mydate = new Date();
var year = mydate.getYear();
if(year < 1000){
year +=1900
}
var day = mydate.getDay();
var month = mydate.getMonth();
var daym = mydate.getDate();
var dayarray = new Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday");
var montharray = new Array("January","Februry","March","April","May","June","July","Augest","September","October","November","December");
// re-use mydate here instead of creating a new object.
var h = mydate.getHours(); // You missed the 's' off 'getHours()'
var m = mydate.getMinutes();
var ampm = h >= 12 ? 'pm' : 'am';
if(h == 24){
h = 0;
} else if (h > 12 ){
h = h - 0;
}
if(h < 10){
h = "0" + h;
}
if(m < 10){
m = "0" + m;
}
// Return the result. Added some spaces to pretty it up a bit
return ("It is currently "+h+":"+m+ampm+" on "+dayarray[day]+" "+ montharray[month]+" "+daym);
}
// Now output the return value of the function.
document.write(renderTime());
How do you display a JavaScript datetime object in the 12 hour format (AM/PM)?
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));
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
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.
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.
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?
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.
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)
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>
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()));
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
Short RegExp for en-US:
var d = new Date();
d = d.toLocaleTimeString().replace(/:\d+ /, ' '); // current time, e.g. "1:54 PM"
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;
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){
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
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.
<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>
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).
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 -->
you can determine am or pm with this simple code
var today=new Date();
var noon=new Date(today.getFullYear(),today.getMonth(),today.getDate(),12,0,0);
var ampm = (today.getTime()<noon.getTime())?'am':'pm';
try this
var date = new Date();
var hours = date.getHours();
var minutes = date.getMinutes();
var seconds = date.getSeconds();
var ampm = hours >= 12 ? "pm" : "am";
function formatTime( d = new Date(), ampm = true )
{
var hour = d.getHours();
if ( ampm )
{
var a = ( hour >= 12 ) ? 'PM' : 'AM';
hour = hour % 12;
hour = hour ? hour : 12; // the hour '0' should be '12'
}
var hour = checkDigit(hour);
var minute = checkDigit(d.getMinutes());
var second = checkDigit(d.getSeconds());
// https://stackoverflow.com/questions/1408289/how-can-i-do-string-interpolation-in-javascript
return ( ampm ) ? `${hour}:${minute}:${second} ${a}` : `${hour}:${minute}:${second}`;
}
function checkDigit(t)
{
return ( t < 10 ) ? `0${t}` : t;
}
document.querySelector("#time1").innerHTML = formatTime();
document.querySelector("#time2").innerHTML = formatTime( new Date(), false );
<p>ampm true: <span id="time1"></span> (default)</p>
<p>ampm false: <span id="time2"></span></p>
function startTime() {
const today = new Date();
let h = today.getHours();
let m = today.getMinutes();
let s = today.getSeconds();
var meridian = h >= 12 ? "PM" : "AM";
h = h % 12;
h = h ? h : 12;
m = m < 10 ? "0" + m : m;
s = s < 10 ? "0" + s : s;
var strTime = h + ":" + m + ":" + s + " " + meridian;
document.getElementById('time').innerText = strTime;
setTimeout(startTime, 1000);
}
startTime();
<h1 id='time'></h1>
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");
var d = new Date();
var hours = d.getHours() % 12;
hours = hours ? hours : 12;
var test = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'][(d.getMonth() + 1)] + " " +
("00" + d.getDate()).slice(-2) + " " +
d.getFullYear() + " " +
("00" + hours).slice(-2) + ":" +
("00" + d.getMinutes()).slice(-2) + ":" +
("00" + d.getSeconds()).slice(-2) + ' ' + (d.getHours() >= 12 ? 'PM' : 'AM');
document.getElementById("demo").innerHTML = test;

var m = today.getMinutes();
var s = today.getSeconds();
h = twelve_hour_time(h);
m = checkTime(m);
s = checkTime(s);
document.getElementById('clock_display').innerHTML =
h + ":" + m + ":" + s +" "+AM_or_PM;
var t = setTimeout(startTime, 1000);
}
function checkTime(i){
if(i < 10){
i = "0" + i;// add zero in front of numbers < 10
}
return i;
}
// CONVERT TO 12 HOUR TIME. SET AM OR PM
function twelve_hour_time(h){
if(h > 12){
h = h - 12;
AM_or_PM = " PM";
}
return h;
}

function getDateTime() {

var dateTime = monthNames[parseInt(month) - 1] + ' ' + day + ' ' + year + ' ' + timewithampm;
return dateTime;
}
Here my solution
function getTime() {
var systemDate = new Date();
var hours = systemDate.getHours();
var minutes = systemDate.getMinutes();
var strampm;
if (hours >= 12) {
strampm= "PM";
} else {
strampm= "AM";
}
hours = hours % 12;
if (hours == 0) {
hours = 12;
}
_hours = checkTimeAddZero(hours);
_minutes = checkTimeAddZero(minutes);
console.log(_hours + ":" + _minutes + " " + strampm);
}
function checkTimeAddZero(i) {
if (i < 10) {
i = "0" + i
}
return i;
}
const formatAMPM = (date) => {
try {
let time = date.split(" ");
let hours = time[4].split(":")[0];
let minutes = time[4].split(":")[1];
hours = hours || 12;
const ampm = hours >= 12 ? " PM" : " AM";
minutes = minutes < 10 ? `${minutes}` : minutes;
hours %= 12;
const strTime = `${hours}:${minutes} ${ampm}`;
return strTime;
} catch (e) {
return "";
}
};
const startTime = "2021-12-07T17:00:00.073Z"
formatAMPM(new Date(startTime).toUTCString())
This is the easiest Way you can Achieve this using ternary operator or you can also use if else instead !
const d = new Date();
let hrs = d.getHours();
let m = d.getMinutes();
// Condition to add zero before minute
let min = m < 10 ? `0${m}` : m;
const currTime = hrs >= 12 ? `${hrs - 12}:${min} pm` : `${hrs}:${min} am`;
console.log(currTime);
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>
I have a Rails app where I'm displaying a realtime clock in my application layout. I'm using this code to make it work:
<div id="time" class="time_display"></div>
<script type="text/javascript">
function checkTime(i) {
if (i < 10) {
i = "0" + i;
}
return i;
}
function startTime() {
var today = new Date();
var h = today.getHours();
var m = today.getMinutes();
var s = today.getSeconds();
// add a zero in front of numbers<10
m = checkTime(m);
s = checkTime(s);
document.getElementById('time').innerHTML = h + ":" + m + ":" + s;
t = setTimeout(function () {
startTime()
}, 500);
}
startTime();
</script>
What I'd like to be able to do is somehow give the user the option to switch between a realtime clock in military time and regular AM/PM time with the AM/PM included but clicking on the div.
I've done some searching but haven't found anything that works too well. I'm open to any solutions someone might have be it JS or jQuery.
Any help would be greatly appreciated. If my question is not clear, please let me know.
Here is code. It get updated only on next tick, but you can manage to fix that if you want
function checkTime(i) {
if (i < 10) {
i = "0" + i;
}
return i;
}
function startTime() {
var today = new Date();
var h = today.getHours();
var m = today.getMinutes();
var s = today.getSeconds();
var ampm = h >= 12 ? 'pm' : 'am';
// add a zero in front of numbers<10
m = checkTime(m);
s = checkTime(s);
var timer = document.getElementById('time');
if (timer.type == 'r') {
h = h % 12;
h = h ? h : 12;
timer.innerHTML = h + ":" + m + ":" + s + " " + ampm;
} else
timer.innerHTML = h + ":" + m + ":" + s;
t = setTimeout(function () {
startTime()
}, 500);
document.getElementById('time').onclick = function () {
if (this.type == 'r')
this.type = 'm';
else
this.type = 'r';
}
}
startTime();
<div id="time" class="time_display"></div>
Really:
var ampm = 'am';
if(hours > 11){
ampm = 'pm';
if(hours > 12)hours = hours-12;
}
if(hours === 0)hours = 12;
Also, you could do something like:
today.toLocaleString().split(',')[1];

How do you display JavaScript datetime in 12 hour AM/PM format?
(31 answers)
Closed 8 years ago.
Currently shows the time in a 24 Hour clock format. Can this be chnaged to show a 12 Hour clock with AM or PM? Thanks
function startTime() {
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').innerHTML = h+":"+m+":"+s;

}
function checkTime(i) {
if (i<10) {i = "0" + i}; // add zero in front of numbers < 10
return i;
}
Yes, if you want to continue formatting manually, you can use something like this:
element.innerHTML = (h > 12 ? h - 12 : h) + ":" + m + ":" + s + (h >= 12 ? " PM" : " AM");
new Date().toLocaleTimeString()
/* returned value: (String)
eg. 11:25:50 AM
or 8:08:41 PM
*/
function startTime() {
var today = new Date();
var h = today.getHours();
var m = today.getMinutes();
var s = today.getSeconds();
m = checkTime(m);
s = checkTime(s);
var ampm = h >= 12 ? 'pm' : 'am';
h = h % 12;
h = h ? h : 12;
m = m < 10 ? '0' + m : m;
