Get time from datetime format

I'm getting this date format from back-end: 1970-01-01T10:59:00Z
How can I get the time from it with JavaScript and put it in this input:
<input type="time" ng-model='content.time' />
Thanks for your help!

You could use the getHours(), getMinutes() and getSeconds() function and concatenate the values.
var result = document.getElementById("result");
var dateTime = new Date();
var hours = new Date().getHours();
var minutes = new Date().getMinutes();
var seconds = new Date().getSeconds();
result.innerHTML = hours + ":" + minutes + ":" + seconds;
<p id="result"></p>

var date = new Date($scope.content.time);
var converted = date.getHours() + ":" + date.getMinutes();
console.log(converted);

This might help you:
var dt = new Date();
var tm = dt.getUTCHours();
For UTC.
Also you can use:
new dt.getHours()
new dt.getMinutes()

var date = new Date("1970-01-01T10:59:00Z");
var converted = date.toLocaleString();
console.log(converted);
Then you'd just assign the converted value to the model.

With angular, and not just vanilla javascript/DOM manipulation, in your controller js:
var dateTime=<referenceToDataRetrievedFromBackEnd>;
/*Format the date you've retrieved*/
var hours = new Date().getHours();
var minutes = new Date().getMinutes();
var seconds = new Date().getSeconds();
var formattedTimeString=hours + ":" + minutes + ":" + seconds
/*This is the part that actual ties the retrieved and reformatted data to the view*/
$scope.content.time=formattedTimeString;

In your controller add this function
var parseDateTime = function (input) {
vars = input.split('T');
date = vars[0].split('-');
time = vars[1].split(':');
//return date in 'yyyy-MM-dd H:i:s'
return date[0] + '-' + date[1] + '-' + date[2] + ' ' + time[0] + ':' + time[1] + ':00';
}
Then you can use it with your datetime
var dateTime = DATE_RECEIVED_FROM_BACKEND;
$scope.content.time = parseDateTime(dateTime);
Hope this helps :)

place this code in the controller where after the data u receive from backend
var d = new Date("1970-01-01T10:59:09Z");//pass the object which have ur date
$scope.content.time=d.getHours() + ":" + d.getMinutes()+":"+ d.getSeconds();

Moment.js Get difference between two dates in the dd:hh:mm:ss format?

I am calculating the time until 11:59PM of the current day. Here is an example.
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.9.0/moment.js"></script>
<script>
setInterval(function() {
var now = moment();
var mid = moment();
mid = mid.endOf('day');
var diffHours = mid.diff(now, 'hours');
var diffMinutes = mid.diff(now, 'minutes');
var diffSeconds = mid.diff(now, 'seconds');
console.log(diffHours + "h " + diffMinutes + "m " + diffSeconds + "s");
}, 1000)
</script>
However, I was hoping it would show me a time such as 20h 13m 49s, instead I am getting 20h 1255m 73500s
I understand this is working as intended pretty much, but how can I achieve the format I am seeking?

You'll want to modify your now variable after each diff.
var hours = mid.diff(now, 'hours'); //Get hours 'till end of day
now.hours(now.hours() + hours);
var minutes = mid.diff(now, 'minutes');

Just for comparison, here's David Stampher's moment.js example from a comment on another answer giving the time until 23:59:59.999 "today" and the same functionality in plain JS:
// Moment.js version
var now = moment();
var mid = moment();
mid = mid.endOf('day');
var diff1 = moment.utc(moment(mid, "DD/MM/YYYY HH:mm:ss")
.diff(moment(now, "DD/MM/YYYY HH:mm:ss")))
.format("HH:mm:ss");
console.log('moment.js: ' + diff1);
// POJS version
var z = (n) => (n<10? '0' : '') + n;
var ms = new Date().setHours(23,59,59,999) - new Date();
var diff2 = z(ms/3.6e6|0) + ':' +
z(ms%3.6e6/6e4|0) + ':' +
z(ms%6e4/1e3|0);
console.log('plain js : ' + diff2);
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.20.1/moment.min.js"></script>

Javascript days +/- from today

For a datepicker I need two dates:
from: today - 7 days,
to: today + 7 days.
I get a currentDate with:
var toDay = new Date();
var curr_date = toDay.getDate();
var curr_month = toDay.getMonth();
curr_month++;
var curr_year = toDay.getFullYear();
var toDay = (curr_month + "/" + curr_date + "/" + curr_year);
How to get 7 days+ and 7 days- dates ? With corresponding month!

As per comment, You can use following code
var myDate = new Date();
myDate.setDate(myDate.getDate() + 7);
var nextWeekDate = ((myDate.getMonth() + 1) + "/" + myDate.getDate() + "/" + myDate.getFullYear());
myDate = new Date();
myDate.setDate(myDate.getDate() -7 );
var prevWeekDate = ((myDate.getMonth() + 1) + "/" + myDate.getDate() + "/" + myDate.getFullYear());
Modified Demo

Pretty simple:
nextWeek.setDate(toDay.getDate() + 7);
lastWeek.setDate(toDay.getDate() - 7);

Javascript saves a date as the number of milliseconds since midnight on january 1st 1970. You can get this time by calling "getTime()" on the Date object. You can then add 7X24X60X60X1000 to get 7 days later, or substract them for 7 days earlier represented in milliseconds. Then call Date.setTime() again.
edit: both these other methods involving getDate() get unpredictable when you are around the start or end of a month.

You can also extend your javascript Date object like this
Date.prototype.addDays = function(days) {
this.setDate(this.getDate() + days);
return this;
};
Date.prototype.substractDays = function(days) {
this.setDate(this.getDate() - days);
return this;
};
//then
var dateDiff=7;
var toDay = new Date();
var futureDay= new Date(toDay.addDays(dateDiff));
var prevDay = new Date(toDay.substractDays(dateDiff*2)); // substracted 14 daysbecause 'toDay' value has been incresed by 7 days
Hope this helps.

You can add /subtract like following
var fdate= new Date();
var numberofdayes= 7;
fdate.setDate(fdate.getDate() + numberofdayes);
(Not sure whether you are asking that or not)
Then you can format it in dd/mm/yyyy using getDate(), getMonth() and getFullYear().
(Don't forget to add 1 to fdate.getMonth())
var formateddate = fdate.getDate()+ '/'+ fdate.getMonth()+1 + '/'+ fdate.getFullYear();

Get last week date with jQuery/Javascript

I'm trying to get the last week date in JavaScript, without the time.
So for example, 10-02-2012, instead of 10-02-12 13:34:56 GMT.
Is there an easy solution out there for this?
Thank you!
Edit:
I'm trying to make this dynamic, so that the resulting variable is always one week before the current date. Here's what I've done to calculate the today variable, if this helps or can be used!
var currentTime = new Date();
var month = currentTime.getMonth() + 1
var day = currentTime.getDate();
var year = currentTime.getFullYear();
var today = month + "-" + day + "-" + year;
alert(today)

I prefer something like this
​
function getLastWeek() {
var today = new Date();
var lastWeek = new Date(today.getFullYear(), today.getMonth(), today.getDate() - 7);
return lastWeek;
}
var lastWeek = getLastWeek();
var lastWeekMonth = lastWeek.getMonth() + 1;
var lastWeekDay = lastWeek.getDate();
var lastWeekYear = lastWeek.getFullYear();
var lastWeekDisplay = lastWeekMonth + "/" + lastWeekDay + "/" + lastWeekYear;
var lastWeekDisplayPadded = ("00" + lastWeekMonth.toString()).slice(-2) + "/" + ("00" + lastWeekDay.toString()).slice(-2) + "/" + ("0000" + lastWeekYear.toString()).slice(-4);
console.log(lastWeekDisplay);
console.log(lastWeekDisplayPadded);
And if you're using jQuery UI, you can do this instead of the manual steps to build the string
var lastWeekDisplay = $.datepicker.formatDate('mm/dd/yy', getLastWeek());
Or for today
var todayDisplay = $.datepicker.formatDate('mm/dd/yy', new Date());

var firstDay = new Date("2009/10/02");
var previousweek= new Date(firstDay.getTime() - 7 * 24 * 60 * 60 * 1000);

We can't have a javascript date question answered without mentioning Moment.js.
moment().subtract('days', 7).format('MM-DD-YYYY')

Possible without external dependencies
new Date().setDate(new Date().getDate() - 7)

If you really want to create this from a full timestamp like 10-02-12 13:34:56 GMT, you might want to do this:
var time = '10-02-12 13:34:56 GMT';
document.write(time.substr(0,7));

use this code to subtract any number of days as i have selected 9 it will give last 10 days result including today
var date = new Date();
var day=date.getDate();
var month=date.getMonth() + 1;
var year=date.getFullYear();
var startDate=day+"/"+month+"/"+year;
var dayBeforeNineDays=moment().subtract(9, 'days').format('DD/MM/YYYY');
startDate=dayBeforeNineDays;
var endDate=day+"/"+month+"/"+year;

function getLastWeek() {
let today = new Date();
let day = today.getDay();
let t = day-1;
let monday = new Date(today.getFullYear(), today.getMonth(), today.getDate() - t - 7); //monday from last week
let sunday = new Date(today.getFullYear(), today.getMonth(), today.getDate() - t - 1); //sunday from ast week
return [monday, sunday];
}
var last_week = getLastWeek();

Getting current date and time in JavaScript

I have a script that prints the current date and time in JavaScript, but the DATE is always wrong. Here is the code:
var currentdate = new Date();
var datetime = "Last Sync: " + currentdate.getDay() + "/" + currentdate.getMonth()
+ "/" + currentdate.getFullYear() + " # "
+ currentdate.getHours() + ":"
+ currentdate.getMinutes() + ":" + currentdate.getSeconds();
It should print 18/04/2012 15:07:33 and prints 3/3/2012 15:07:33

.getMonth() returns a zero-based number so to get the correct month you need to add 1, so calling .getMonth() in may will return 4 and not 5.
So in your code we can use currentdate.getMonth()+1 to output the correct value. In addition:
.getDate() returns the day of the month <- this is the one you want
.getDay() is a separate method of the Date object which will return an integer representing the current day of the week (0-6) 0 == Sunday etc
so your code should look like this:
var currentdate = new Date();
var datetime = "Last Sync: " + currentdate.getDate() + "/"
+ (currentdate.getMonth()+1) + "/"
+ currentdate.getFullYear() + " # "
+ currentdate.getHours() + ":"
+ currentdate.getMinutes() + ":"
+ currentdate.getSeconds();
JavaScript Date instances inherit from Date.prototype. You can modify the constructor's prototype object to affect properties and methods inherited by JavaScript Date instances
You can make use of the Date prototype object to create a new method which will return today's date and time. These new methods or properties will be inherited by all instances of the Date object thus making it especially useful if you need to re-use this functionality.
// For todays date;
Date.prototype.today = function () {
return ((this.getDate() < 10)?"0":"") + this.getDate() +"/"+(((this.getMonth()+1) < 10)?"0":"") + (this.getMonth()+1) +"/"+ this.getFullYear();
}
// For the time now
Date.prototype.timeNow = function () {
return ((this.getHours() < 10)?"0":"") + this.getHours() +":"+ ((this.getMinutes() < 10)?"0":"") + this.getMinutes() +":"+ ((this.getSeconds() < 10)?"0":"") + this.getSeconds();
}
You can then simply retrieve the date and time by doing the following:
var newDate = new Date();
var datetime = "LastSync: " + newDate.today() + " # " + newDate.timeNow();
Or call the method inline so it would simply be -
var datetime = "LastSync: " + new Date().today() + " # " + new Date().timeNow();

To get time and date you should use
new Date().toLocaleString();
>> "09/08/2014, 2:35:56 AM"
To get only the date you should use
new Date().toLocaleDateString();
>> "09/08/2014"
To get only the time you should use
new Date().toLocaleTimeString();
>> "2:35:56 AM"
Or if you just want the time in the format hh:mm without AM/PM for US English
new Date().toLocaleTimeString('en-US', { hour12: false,
hour: "numeric",
minute: "numeric"});
>> "02:35"
or for British English
new Date().toLocaleTimeString('en-GB', { hour: "numeric",
minute: "numeric"});
>> "02:35"

Short
I develop Steve answer to get exactly what OP need
new Date().toLocaleString().replace(',','')
console.log(new Date().toLocaleString().replace(',',''));

var currentdate = new Date();
var datetime = "Last Sync: " + currentdate.getDate() + "/"+(currentdate.getMonth()+1)
+ "/" + currentdate.getFullYear() + " # "
+ currentdate.getHours() + ":"
+ currentdate.getMinutes() + ":" + currentdate.getSeconds();
Change .getDay() method to .GetDate() and add one to month, because it counts months from 0.

This should do the trick:
function dateToString(date) {
var month = date.getMonth() + 1;
var day = date.getDate();
var dateOfString = (("" + day).length < 2 ? "0" : "") + day + "/";
dateOfString += (("" + month).length < 2 ? "0" : "") + month + "/";
dateOfString += date.getFullYear();
return dateOfString;
}
var currentdate = new Date();
var datetime = "Last Sync: ";
datetime += dateToString(currentdate );
datetime += + currentdate.getHours() + ":"
+ currentdate.getMinutes() + ":"
+ currentdate.getSeconds();

Basic JS (good to learn): we use the Date() function and do all that we need to show the date and day in our custom format.
var myDate = new Date();
let daysList = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];
let monthsList = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Aug', 'Oct', 'Nov', 'Dec'];
let date = myDate.getDate();
let month = monthsList[myDate.getMonth()];
let year = myDate.getFullYear();
let day = daysList[myDate.getDay()];
let today = `${date} ${month} ${year}, ${day}`;
let amOrPm;
let twelveHours = function (){
if(myDate.getHours() > 12)
{
amOrPm = 'PM';
let twentyFourHourTime = myDate.getHours();
let conversion = twentyFourHourTime - 12;
return `${conversion}`
}else {
amOrPm = 'AM';
return `${myDate.getHours()}`}
};
let hours = twelveHours();
let minutes = myDate.getMinutes();
let currentTime = `${hours}:${minutes} ${amOrPm}`;
console.log(today + ' ' + currentTime);
Node JS (quick & easy): Install the npm pagckage using (npm install date-and-time), then run the below.
let nodeDate = require('date-and-time');
let now = nodeDate.format(new Date(), 'DD-MMMM-YYYY, hh:mm:ss a');
console.log(now);

Short and simple:-
console.log(new Date().toLocaleString());
Reference

I have found the simplest way to get current date and time in JavaScript from here - How to get current Date and Time using JavaScript
var today = new Date();
var date = today.getFullYear()+'-'+(today.getMonth()+1)+'-'+today.getDate();
var time = today.getHours() + ":" + today.getMinutes() + ":" + today.getSeconds();
var CurrentDateTime = date+' '+time;

getDay() gets the day of the week. 3 is Wednesday. You want getDate(), that will return 18.
Also getMonth() starts at 0, you need to add 1 to get 4 (April).
DEMO: http://jsfiddle.net/4zVxp/

You need to use getDate() to get the date part. The getDay() function returns the day number (Sunday = 0, Monday = 1...), and the getMonth() returns a 0 based index, so you need to increment it by 1.
var currentdate = new Date();
var datetime = "Last Sync: " + currentdate.getDate() + "/"+ (parseInt(currentdate.getMonth()) + 1)
+ "/" + currentdate.getFullYear() + " # "
+ currentdate.getHours() + ":"
+ currentdate.getMinutes() + ":" + currentdate.getSeconds();

const date = new Date()
console.log(date.toLocaleTimeString("en-us", {timeStyle: "medium"})) // Only Time
console.log(date.toLocaleString()) // For both Date and Time
For Documentation

function getTimeStamp() {
var now = new Date();
return ((now.getMonth() + 1) + '/' + (now.getDate()) + '/' + now.getFullYear() + " " + now.getHours() + ':'
+ ((now.getMinutes() < 10) ? ("0" + now.getMinutes()) : (now.getMinutes())) + ':' + ((now.getSeconds() < 10) ? ("0" + now
.getSeconds()) : (now.getSeconds())));
}

get current date and time
var now = new Date();
var datetime = now.getFullYear()+'/'+(now.getMonth()+1)+'/'+now.getDate();
datetime += ' '+now.getHours()+':'+now.getMinutes()+':'+now.getSeconds();

This question is quite old and the answers are too. Instead of those monstrous functions, we now can use moment.js to get the current date, which actually makes it very easy. All that has to be done is including moment.js in our project and get a well formated date, for example, by:
moment().format("dddd, MMMM Do YYYY, h:mm:ss a");
I think that makes it way easier to handle dates in javascript.

.getDay returns day of week. You need .getDate instead.
.getMonth returns values from 0 to 11. You'll need to add 1 to the result to get "human" month number.

This little code is easy and works everywhere.
<p id="dnt"></p>
<script>
document.getElementById("dnt").innerHTML = Date();
</script>
there is room to design

function UniqueDateTime(format='',language='en-US'){
//returns a meaningful unique number based on current time, and milliseconds, making it virtually unique
//e.g : 20170428-115833-547
//allows personal formatting like more usual :YYYYMMDDHHmmSS, or YYYYMMDD_HH:mm:SS
var dt = new Date();
var modele="YYYYMMDD-HHmmSS-mss";
if (format!==''){
modele=format;
}
modele=modele.replace("YYYY",dt.getFullYear());
modele=modele.replace("MM",(dt.getMonth()+1).toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false}));
modele=modele.replace("DD",dt.getDate().toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false}));
modele=modele.replace("HH",dt.getHours().toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false}));
modele=modele.replace("mm",dt.getMinutes().toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false}));
modele=modele.replace("SS",dt.getSeconds().toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false}));
modele=modele.replace("mss",dt.getMilliseconds().toLocaleString(language, {minimumIntegerDigits: 3, useGrouping:false}));
return modele;
}

dt= new Date();
alert(dt.toISOString().substring(8,10) + "/" +
dt.toISOString().substring(5,7)+ "/" +
dt.toISOString().substring(0,4) + " " +
dt.toTimeString().substring(0,8))

var datetime = new Date().toLocaleString().slice(0,9) +" "+new Date(new Date()).toString().split(' ')[4];
console.log(datetime);

I needed to figure this out for a slate in after effects. Here's what I came up with after taking elements from a few different sources -- Formatting is MM/DD/YYYY HH:MM AM/PM
D = new Date(Date(00));
M = D.getMonth()+1;
H = D.getHours();
Mi = D.getMinutes();
N = "AM"
if (H >= 12)
N = "PM"
if (H > 12)
{
H = H-12
}
amtOfZeroes = 2;
isNeg = false;
if (M < 0)
{
M = Math.abs(M);
isNeg = true;
}
Mo = Math.round(M) + "";
while(Mo.length < amtOfZeroes)
{
Mo = "0" + Mo;
}
if (isNeg)
Mo = "-" + Mo;
if (H < 0)
{
H = Math.abs(H);
isNeg = true;
}
Ho = Math.round(H) + "";
while(Ho.length < amtOfZeroes)
{
Ho = "0" + Ho;
}
if (isNeg)
Ho = "-" + Ho;
if (Mi < 0)
{
Mi = Math.abs(Mi);
isNeg = true;
}
Min = Math.round(Mi) + "";
while(Min.length < amtOfZeroes)
{
Min = "0" + Min;
}
if (isNeg)
Min = "-" + Min;
T = Ho + ":" + (Min)
Mo + "/" + D.getDate() + "/" + D.getFullYear() + " " + T + " " + N

If someone is in search of function
console.log(formatAMPM());
function formatAMPM() {
var date = new Date();
var hours = date.getHours();
var minutes = date.getMinutes();
var seconds = date.getSeconds();
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;
return strTime = date.getMonth() + '/' + date.getDay()+'/'+date.getFullYear()+' '+ hours + ':' + minutes +':'+ seconds + " " +ampm;
}

function display_c(){
var refresh = 1000; // Refresh rate in milli seconds
mytime = setTimeout('display_ct()', refresh)

This example of UK Time Zone.. set offset for specific Time Zone.
Example : for India : +05:30 , UK : +1
function realUKTime() {
// create Date object for current location
var d = new Date();
offset ='+1';
// convert to msec
// subtract local time zone offset
// get UTC time in msec
var utc = d.getTime() + (d.getTimezoneOffset() * 60000);
// create new Date object for different city
// using supplied offset
var nd = new Date(utc + (3600000*offset));
// return time as a string
var s = nd.getSeconds();
var i = nd.getMinutes();
var h = nd.getHours();
var cDate = nd.getDate();
var m = nd.getUTCMonth();
var y = nd.getFullYear();
var newUkTime = nd.toDateString() + " "+ (Number(h)-1)+":"+i+':'+s
$("#realTime").html(newUkTime);
}
setInterval(realUKTime(),1000);
Output :: Mon Dec 27 2021 12:6:3

we can use :
new Date().toLocaleDateString() to fetch current date and
new Date().toLocaleTimeString() to fetch current time
Ex:
const date = new Date().toLocaleDateString();
const time = new Date().toLocaleTimeString();
