Convert UTC date time to local date time
JavascriptJqueryDatetimeTimezoneUtcJavascript Problem Overview
From the server I get a datetime variable in this format: 6/29/2011 4:52:48 PM and it is in UTC time. I want to convert it to the current user’s browser time zone using JavaScript.
How this can be done using JavaScript or jQuery?
Javascript Solutions
Solution 1 - Javascript
Append 'UTC' to the string before converting it to a date in javascript:
var date = new Date('6/29/2011 4:52:48 PM UTC');
date.toString() // "Wed Jun 29 2011 09:52:48 GMT-0700 (PDT)"
Solution 2 - Javascript
In my point of view servers should always in the general case return a datetime in the standardized ISO 8601-format.
More info here:
IN this case the server would return '2011-06-29T16:52:48.000Z' which would feed directly into the JS Date object.
var utcDate = '2011-06-29T16:52:48.000Z'; // ISO-8601 formatted date returned from server
var localDate = new Date(utcDate);
The localDate will be in the right local time which in my case would be two hours later (DK time).
You really don't have to do all this parsing which just complicates stuff, as long as you are consistent with what format to expect from the server.
Solution 3 - Javascript
This is an universal solution:
function convertUTCDateToLocalDate(date) {
var newDate = new Date(date.getTime()+date.getTimezoneOffset()*60*1000);
var offset = date.getTimezoneOffset() / 60;
var hours = date.getHours();
newDate.setHours(hours - offset);
return newDate;
}
Usage:
var date = convertUTCDateToLocalDate(new Date(date_string_you_received));
Display the date based on the client local setting:
date.toLocaleString();
Solution 4 - Javascript
For me above solutions didn't work.
With IE the UTC date-time conversion to local is little tricky.
For me, the date-time from web API is '2018-02-15T05:37:26.007' and I wanted to convert as per local timezone so I used below code in JavaScript.
var createdDateTime = new Date('2018-02-15T05:37:26.007' + 'Z');
Solution 5 - Javascript
You should get the (UTC) offset (in minutes) of the client:
var offset = new Date().getTimezoneOffset();
And then do the correspondent adding or substraction to the time you get from the server.
Hope this helps.
Solution 6 - Javascript
This works for me:
function convertUTCDateToLocalDate(date) {
var newDate = new Date(date.getTime() - date.getTimezoneOffset()*60*1000);
return newDate;
}
Solution 7 - Javascript
Put this function in your head:
<script type="text/javascript">
function localize(t)
{
var d=new Date(t+" UTC");
document.write(d.toString());
}
</script>
Then generate the following for each date in the body of your page:
<script type="text/javascript">localize("6/29/2011 4:52:48 PM");</script>
To remove the GMT and time zone, change the following line:
document.write(d.toString().replace(/GMT.*/g,""));
Solution 8 - Javascript
This is a simplified solution based on Adorjan Princ´s answer:
function convertUTCDateToLocalDate(date) {
var newDate = new Date(date);
newDate.setMinutes(date.getMinutes() - date.getTimezoneOffset());
return newDate;
}
or simpler (though it mutates the original date):
function convertUTCDateToLocalDate(date) {
date.setMinutes(date.getMinutes() - date.getTimezoneOffset());
return date;
}
Usage:
var date = convertUTCDateToLocalDate(new Date(date_string_you_received));
Solution 9 - Javascript
After trying a few others posted here without good results, this seemed to work for me:
convertUTCDateToLocalDate: function (date) {
return new Date(Date.UTC(date.getFullYear(), date.getMonth(), date.getDate(), date.getHours(), date.getMinutes(), date.getSeconds()));
}
And this works to go the opposite way, from Local Date to UTC:
convertLocalDatetoUTCDate: function(date){
return new Date(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(), date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds());
}
Solution 10 - Javascript
Add the time zone at the end, in this case 'UTC':
theDate = new Date( Date.parse('6/29/2011 4:52:48 PM UTC'));
after that, use toLocale()* function families to display the date in the correct locale
theDate.toLocaleString(); // "6/29/2011, 9:52:48 AM"
theDate.toLocaleTimeString(); // "9:52:48 AM"
theDate.toLocaleDateString(); // "6/29/2011"
Solution 11 - Javascript
Matt's answer is missing the fact that the daylight savings time could be different between Date() and the date time it needs to convert - here is my solution:
function ConvertUTCTimeToLocalTime(UTCDateString)
{
var convertdLocalTime = new Date(UTCDateString);
var hourOffset = convertdLocalTime.getTimezoneOffset() / 60;
convertdLocalTime.setHours( convertdLocalTime.getHours() + hourOffset );
return convertdLocalTime;
}
And the results in the debugger:
UTCDateString: "2014-02-26T00:00:00"
convertdLocalTime: Wed Feb 26 2014 00:00:00 GMT-0800 (Pacific Standard Time)
Solution 12 - Javascript
Use this for UTC and Local time convert and vice versa.
//Covert datetime by GMT offset
//If toUTC is true then return UTC time other wise return local time
function convertLocalDateToUTCDate(date, toUTC) {
date = new Date(date);
//Local time converted to UTC
console.log("Time: " + date);
var localOffset = date.getTimezoneOffset() * 60000;
var localTime = date.getTime();
if (toUTC) {
date = localTime + localOffset;
} else {
date = localTime - localOffset;
}
date = new Date(date);
console.log("Converted time: " + date);
return date;
}
Solution 13 - Javascript
In case you don't mind usingmoment.js and your time is in UTC just use the following:
moment.utc('6/29/2011 4:52:48 PM').toDate();
if your time is not in utc but any other locale known to you, then use following:
moment('6/29/2011 4:52:48 PM', 'MM-DD-YYYY', 'fr').toDate();
if your time is already in local, then use following:
moment('6/29/2011 4:52:48 PM', 'MM-DD-YYYY');
Solution 14 - Javascript
if you have 2021-12-28T18:00:45.959Z format you can use this in js :
// myDateTime is 2021-12-28T18:00:45.959Z
myDate = new Date(myDateTime).toLocaleDateString('en-US');
// myDate is 12/28/2021
myTime = new Date(myDateTime).toLocaleTimeString('en-US');
// myTime is 9:30:45 PM
you just have to put your area string instead of "en-US" (e.g. "fa-IR").
Solution 15 - Javascript
To me the simplest seemed using
datetime.setUTCHours(datetime.getHours());
datetime.setUTCMinutes(datetime.getMinutes());
(i thought the first line could be enough but there are timezones which are off in fractions of hours)
Solution 16 - Javascript
Using YYYY-MM-DD hh:mm:ss format :
var date = new Date('2011-06-29T16:52:48+00:00');
date.toString() // "Wed Jun 29 2011 09:52:48 GMT-0700 (PDT)"
For converting from the YYYY-MM-DD hh:mm:ss format, make sure your date follow the ISO 8601 format.
Year:
YYYY (eg 1997)
Year and month:
YYYY-MM (eg 1997-07)
Complete date:
YYYY-MM-DD (eg 1997-07-16)
Complete date plus hours and minutes:
YYYY-MM-DDThh:mmTZD (eg 1997-07-16T19:20+01:00)
Complete date plus hours, minutes and seconds:
YYYY-MM-DDThh:mm:ssTZD (eg 1997-07-16T19:20:30+01:00)
Complete date plus hours, minutes, seconds and a decimal fraction of a second
YYYY-MM-DDThh:mm:ss.sTZD (eg 1997-07-16T19:20:30.45+01:00) where:
YYYY = four-digit year
MM = two-digit month (01=January, etc.)
DD = two-digit day of month (01 through 31)
hh = two digits of hour (00 through 23) (am/pm NOT allowed)
mm = two digits of minute (00 through 59)
ss = two digits of second (00 through 59)
s = one or more digits representing a decimal fraction of a second
TZD = time zone designator (Z or +hh:mm or -hh:mm)
Important things to note
- You must separate the date and the time by a
T, a space will not work in some browsers - You must set the timezone using this format
+hh:mm, using a string for a timezone (ex. : 'UTC') will not work in many browsers.+hh:mmrepresent the offset from the UTC timezone.
Solution 17 - Javascript
A JSON date string (serialized in C#) looks like "2015-10-13T18:58:17".
In angular, (following Hulvej) make a localdate filter:
myFilters.filter('localdate', function () {
return function(input) {
var date = new Date(input + '.000Z');
return date;
};
})
Then, display local time like:
{{order.createDate | localdate | date : 'MMM d, y h:mm a' }}
Solution 18 - Javascript
For me, this works well
if (typeof date === "number") {
time = new Date(date).toLocaleString();
} else if (typeof date === "string"){
time = new Date(`${date} UTC`).toLocaleString();
}
Solution 19 - Javascript
This is what I'm doing to convert UTC to my Local Time:
const dataDate = '2020-09-15 07:08:08'
const utcDate = new Date(dataDate);
const myLocalDate = new Date(Date.UTC(
utcDate.getFullYear(),
utcDate.getMonth(),
utcDate.getDate(),
utcDate.getHours(),
utcDate.getMinutes()
));
document.getElementById("dataDate").innerHTML = dataDate;
document.getElementById("myLocalDate").innerHTML = myLocalDate;
<p>UTC<p>
<p id="dataDate"></p>
<p>Local(GMT +7)<p>
<p id="myLocalDate"></p>
Result: Tue Sep 15 2020 14:08:00 GMT+0700 (Indochina Time).
Solution 20 - Javascript
I Answering This If Any one want function that display converted time to specific id element and apply date format string yyyy-mm-dd here date1 is string and ids is id of element that time going to display.
function convertUTCDateToLocalDate(date1, ids)
{
var newDate = new Date();
var ary = date1.split(" ");
var ary2 = ary[0].split("-");
var ary1 = ary[1].split(":");
var month_short = Array('Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec');
newDate.setUTCHours(parseInt(ary1[0]));
newDate.setUTCMinutes(ary1[1]);
newDate.setUTCSeconds(ary1[2]);
newDate.setUTCFullYear(ary2[0]);
newDate.setUTCMonth(ary2[1]);
newDate.setUTCDate(ary2[2]);
ids = document.getElementById(ids);
ids.innerHTML = " " + newDate.getDate() + "-" + month_short[newDate.getMonth() - 1] + "-" + newDate.getFullYear() + " " + newDate.getHours() + ":" + newDate.getMinutes() + ":" + newDate.getSeconds();
}
i know that answer has been already accepted but i get here cause of google and i did solve with getting inspiration from accepted answer so i did want to just share it if someone need.
Solution 21 - Javascript
@Adorojan's answer is almost correct. But addition of offset is not correct since offset value will be negative if browser date is ahead of GMT and vice versa.
Below is the solution which I came with and is working perfectly fine for me:
// Input time in UTC
var inputInUtc = "6/29/2011 4:52:48";
var dateInUtc = new Date(Date.parse(inputInUtc+" UTC"));
//Print date in UTC time
document.write("Date in UTC : " + dateInUtc.toISOString()+"<br>");
var dateInLocalTz = convertUtcToLocalTz(dateInUtc);
//Print date in local time
document.write("Date in Local : " + dateInLocalTz.toISOString());
function convertUtcToLocalTz(dateInUtc) {
//Convert to local timezone
return new Date(dateInUtc.getTime() - dateInUtc.getTimezoneOffset()*60*1000);
}
Solution 22 - Javascript
Based on @digitalbath answer, here is a small function to grab the UTC timestamp and display the local time in a given DOM element (using jQuery for this last part):
https://jsfiddle.net/moriz/6ktb4sv8/1/
<div id="eventTimestamp" class="timeStamp">
</div>
<script type="text/javascript">
// Convert UTC timestamp to local time and display in specified DOM element
function convertAndDisplayUTCtime(date,hour,minutes,elementID) {
var eventDate = new Date(''+date+' '+hour+':'+minutes+':00 UTC');
eventDate.toString();
$('#'+elementID).html(eventDate);
}
convertAndDisplayUTCtime('06/03/2015',16,32,'eventTimestamp');
</script>
Solution 23 - Javascript
You can use momentjs ,moment(date).format() will always give result in local date.
Bonus , you can format in any way you want. For eg.
moment().format('MMMM Do YYYY, h:mm:ss a'); // September 14th 2018, 12:51:03 pm
moment().format('dddd'); // Friday
moment().format("MMM Do YY");
For more details you can refer Moment js website
Solution 24 - Javascript
this worked well for me with safari/chrome/firefox :
const localDate = new Date(`${utcDate.replace(/-/g, '/')} UTC`);
Solution 25 - Javascript
I believe this is the best solution:
let date = new Date(objDate);
date.setMinutes(date.getTimezoneOffset());
This will update your date by the offset appropriately since it is presented in minutes.
Solution 26 - Javascript
using dayjs library:
(new Date()).toISOString(); // returns 2021-03-26T09:58:57.156Z (GMT time)
dayjs().format('YYYY-MM-DD HH:mm:ss,SSS'); // returns 2021-03-26 10:58:57,156 (local time)
(in nodejs, you must do before using it: const dayjs = require('dayjs');
in other environtments, read dayjs documentation.)
Solution 27 - Javascript
In Angular I used Ben's answer this way:
$scope.convert = function (thedate) {
var tempstr = thedate.toString();
var newstr = tempstr.toString().replace(/GMT.*/g, "");
newstr = newstr + " UTC";
return new Date(newstr);
};
Edit: Angular 1.3.0 added UTC support to date filter, I haven't use it yet but it should be easier, here is the format:
{{ date_expression | date : format : timezone}}
Solution 28 - Javascript
I wrote a nice little script that takes a UTC epoch and converts it the client system timezone and returns it in d/m/Y H:i:s (like the PHP date function) format:
getTimezoneDate = function ( e ) {
function p(s) { return (s < 10) ? '0' + s : s; }
var t = new Date(0);
t.setUTCSeconds(e);
var d = p(t.getDate()),
m = p(t.getMonth()+1),
Y = p(t.getFullYear()),
H = p(t.getHours()),
i = p(t.getMinutes()),
s = p(t.getSeconds());
d = [d, m, Y].join('/') + ' ' + [H, i, s].join(':');
return d;
};
Solution 29 - Javascript
I've created one function which converts all the timezones into local time.
I did not used getTimezoneOffset(), because it does not returns proper offset value
Requirements:
1. npm i moment-timezone
function utcToLocal(utcdateTime, tz) {
var zone = moment.tz(tz).format("Z") // Actual zone value e:g +5:30
var zoneValue = zone.replace(/[^0-9: ]/g, "") // Zone value without + - chars
var operator = zone && zone.split("") && zone.split("")[0] === "-" ? "-" : "+" // operator for addition subtraction
var localDateTime
var hours = zoneValue.split(":")[0]
var minutes = zoneValue.split(":")[1]
if (operator === "-") {
localDateTime = moment(utcdateTime).subtract(hours, "hours").subtract(minutes, "minutes").format("YYYY-MM-DD HH:mm:ss")
} else if (operator) {
localDateTime = moment(utcdateTime).add(hours, "hours").add(minutes, "minutes").format("YYYY-MM-DD HH:mm:ss")
} else {
localDateTime = "Invalid Timezone Operator"
}
return localDateTime
}
utcToLocal("2019-11-14 07:15:37", "Asia/Kolkata")
//Returns "2019-11-14 12:45:37"

In my case, I had to find the difference of dates in seconds. The date was a UTC date string, so I converted it to a local date object. This is what I did:
let utc1 = new Date();
let utc2 = null;
const dateForCompare = new Date(valueFromServer);
dateForCompare.setTime(dateForCompare.getTime() - dateForCompare.getTimezoneOffset() *
60000);
utc2 = dateForCompare;
const seconds = Math.floor(utc1 - utc2) / 1000;

tl;dr (new Date('6/29/2011 4:52:48 PM UTC')).toString()
The source string must specify a time zone or UTC.
One-liner:
(new Date('6/29/2011 4:52:48 PM UTC')).toString()
Result in one of my web browsers:
"Wed Jun 29 2011 09:52:48 GMT-0700 (Pacific Daylight Time)"
This approach even selects standard/daylight time appropriately.
(new Date('1/29/2011 4:52:48 PM UTC')).toString()
Result in my browser:
"Sat Jan 29 2011 08:52:48 GMT-0800 (Pacific Standard Time)"

UTC to local to ISO - Using Molp Burnbright answer
because server only accepts ISO date-time so I converted UTC to my local timezone and sent it to server in ISO format
declare this somewhere
function convertUTCDateToLocalDate(date) {
var newDate = new Date(date.getTime() - date.getTimezoneOffset()*60*1000);
return newDate;
}
and do this where you need local datetime in ISO format convertUTCDateToLocalDate(date).toISOString()
Solution 33 - Javascript
This works on my side
Option 1: If date format is something like "yyyy-mm-dd" or "yyyy-mm-dd H:n:s", ex: "2021-12-16 06:07:40"
With this format It doesnt really know if its a local format or a UTC time. So since we know that the date is a UTC we have to make sure that JS will know that its a UTC. So we have to set the date as UTC.
function setDateAsUTC(d) {
let date = new Date(d);
return new Date(
Date.UTC(
date.getFullYear(),
date.getMonth(),
date.getDate(),
date.getHours(),
date.getMinutes(),
date.getSeconds()
)
);
}
and then use it
let d = "2021-12-16 06:07:40";
setDateAsUTC(d).toLocaleString();
// output: 12/16/2021, 6:07:40 AM
Options 2: If UTC date format is ISO-8601. Mostly servers timestampz format are in ISO-8601 ex: '2011-06-29T16:52:48.000Z'. With this we can just pass it to the date function and toLocaleString() function.
let newDate = "2011-06-29T16:52:48.000Z"
new Date(newDate).toLocaleString();
//output: 6/29/2011, 4:52:48 PM
Solution 34 - Javascript
I had a similar problem, I used following code code (JavaScript) to convert UTC to local time
let a = new Date()
a = a.getFullYear().toString() + "-" + (a.getMonth() + 1).toString().padStart(2, "0") + "-" + a.getDate().toString().padStart(2, "0")
console.log(a)
Solution 35 - Javascript
function getUTC(str) {
var arr = str.split(/[- :]/);
var utc = new Date(arr[0], arr[1]-1, arr[2], arr[3], arr[4], arr[5]);
utc.setTime(utc.getTime() - utc.getTimezoneOffset()*60*1000)
return utc;
}
For others who visit - use this function to get a Local date object from a UTC string, should take care of DST and will work on IE, IPhone etc.
We split the string (Since JS Date parsing is not supported on some browsers) We get difference from UTC and subtract it from the UTC time, which gives us local time. Since offset returned is calculated with DST (correct me if I am wrong), so it will set that time back in the variable "utc". Finally return the date object.
Solution 36 - Javascript
You can get it done using moment.js file.
Its simple you have just mention the place of the timezone.
Example: If you to convert your datetime to Asia/Kolkata timezone,you have to just mention the name of the timezone place obtained from moment.js
var UTCDateTime="Your date obtained from UTC";
var ISTleadTime=(moment.tz(UTCDateTime, "Africa/Abidjan")).tz("Asia/Kolkata").format('YYYY-MM-DD LT');

For the TypeScript users, here is a helper function:
// Typescript Type: Date Options
interface DateOptions {
day: 'numeric' | 'short' | 'long',
month: 'numeric',
year: 'numeric',
timeZone: 'UTC',
};
// Helper Function: Convert UTC Date To Local Date
export const convertUTCDateToLocalDate = (date: Date) => {
// Date Options
const dateOptions: DateOptions = {
day: 'numeric',
month: 'numeric',
year: 'numeric',
timeZone: 'UTC',
};
// Formatted Date (4/20/2020)
const formattedDate = new Date(date.getTime() - date.getTimezoneOffset() * 60 * 1000).toLocaleString('en-US', dateOptions);
return formattedDate;
};
