Given a Date string such as var input = '2019-09-19 13:07:09'
How can I convert that string to a different time zone? Knowing that input is in UTC.
I tried the following:
var input = '2019-09-19 13:07:09';
var convertTo = "US/Eastern";
var dateConverted = moment.tz(input, "YYYY-MM-DD hh:mm:ss", convertTo);
dateConverted remains the same as input after that code is executed.
I also tried:
var input = '2019-09-19 13:07:09';
var convertTo = "US/Eastern";
var inUTC = (moment(input).utc());
var dateConverted = moment.tz(inUTC, "YYYY-MM-DD hh:mm:ss", convertTo);
But in this case, the problem is that inUTC becomes Thu Sep 19 2019 20:07:09 GMT+0000 after (moment(input).utc());
I expect the date to be converted to EST which would be 2019-09-19 09:07:09
Any ideas how to solve this? Thanks!
try this :
var input = '2019-09-19 13:07:09';
var offUtc = moment.utc(input, 'YYYY-MM-DD HH:mm:ss');
var convertTo = "US/Eastern";
var dateConverted = offUtc.clone().tz(convertTo);

How can I convert this date: 29/12/2022 where:
29 is day,
12 is month,
2022 is year,
to ISO string.
I tried this:
var dateStr = "29/12/2022";
var parts = dateStr.split("/")
var myDate = new Date(parseInt(parts[2]), parseInt(parts[1]) - 1, parseInt(parts[0]));
console.log(myDate.toISOString());
// 2024-05-11T22:00:00.000Z this is wrong
I was expecting different result.
There is no need to parseInt and to remove 1 to the month.
var dateStr = "29/12/2022";
var parts = dateStr.split("/")
var myDate = new Date(`${parts[2]}-${parts[1]}-${parts[0]}`);
console.log(myDate.toISOString());
In my code usually I do something like this:
const dateStr = "29/12/2022";
const parts = dateStr.split("/");
const date = new Date(0); // It will set hours, minutes, and seconds to 0
date.setDate(parts[0]);
date.setMonth(parts[1]-1);
date.setFullYear(parts[2]);
console.log(date.toISOString());
It may not be the most optimal way but you could do it this way as long as the month when it is a single digit is sent with zero at the beginning type: 01 -> January
let date = '29/12/2022';
let dateFormat = date[3]+date[4]+"-"+date[0]+date[1]+"-
"+date[6]+date[7]+date[8]+date[9]
// 12-29-2022
let mydate = new Date(dateFormat)
// Thu Dec 29 2022 00:00:00 GMT-0500
how can i extract time from datetime format.
my datetime format is given below.
var datetime =2000-01-01 01:00:00 UTC;
I only want to get the time 01.00 as 01
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleTimeString
Date.prototype.toLocaleTimeString()
Returns a string with a locality sensitive representation of the time portion of this date based on system settings.
var time = datetime.toLocaleTimeString();
Update:
The new locales and options arguments let applications specify the
language whose formatting conventions should be used and customize the
behavior of the function. In older implementations, which ignore the
locales and options arguments, the locale used and the form of the
string returned are entirely implementation dependent.
// Depending on timezone, your results will vary
var event = new Date('August 19, 1975 23:15:30 GMT+00:00');
console.log(event.toLocaleTimeString('en-US'));
// expected output: 1:15:30 AM
console.log(event.toLocaleTimeString('it-IT'));
// expected output: 01:15:30
What about these methods
new Date().getHours()
new Date().getMinutes()
For example:
var d = new Date();
var n = d.getHours();
Edited
Return the hour, according to universal time:
new Date().getUTCHours()
Example:
var d = new Date();
var n = d.getUTCHours();
As an alternative if you want to get the time from a string -
var datetime ="2000-01-01 01:00:00 UTC";
var myTime = datetime.substr(11, 2);
alert(myTime) //01
with the moment.js library it works in this way:
var result = moment().format('hh');
alert(result);
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.17.1/moment.min.js"></script>
var datetime = ("2000-01-01 01:00:00 UTC");
var d1 = new Date(datetime);
var minute = d1.getUTCMinutes();
var hour = d1.getUTCHours();
if(minute > 0)
alert(hour+"."+minute);
else
alert(hour);
Demo
var date1 = new Date(1945,10,20, 17,30)
var date2 = new Date(1970,1,8, 12,00)
console.log(date1.getHours() - 8 + (date1.getMinutes()/60))
console.log(date2.getHours() - 8 + (date2.getMinutes()/60))
Use the following code:
var datetime = "2000-01-01 01:00:00 UTC";
var dt = new Date(datetime);
var hr = dt.getUTCHours();
if(hr > 12) {
hr -= 12;
}
alert(hr);

I have done it! It looks like this:
console.log(new Date().toLocaleTimeString() + " " + new Date().getSeconds() + " seconds");
Assuming you have a Date object like
var datetime = new Date("2000-01-01 01:00:00 UTC"); // might not parse correctly in every engine
// or
var datetime = new Date(Date.UTC(2000, 0, 1, 1, 0, 0));
then use the getUTCHours method:
datetime.getUTCHours(); // 1
I hope you can find a solution here.
let preDateTime = new Date("2022-03-31 22:26:00");
let newTime = preDateTime.toLocaleTimeString('en-US');

let seconds = newTime.split(":")[2].replace(amPm,'');;
let noAmPm = newTime.replace(amPm,'');
let noAmPmSeconds = noAmPm.replace(":"+seconds,'');
let noSeconds = newTime.replace(":"+seconds,' ');
if(parseInt(hour)<9){
newTime = "0"+newTime;
noAmPm = "0"+noAmPm

I have another question on SO Unable to read date cell. This question is related to last question but more generic. How to convert Raw date, which represents number of days since 1st Jan 1900, to a javascript date type? [ Forget office365 ].
I have number of days elapsed since 1st Jan 1900. How can I get the date from it. For ex: I need a date after 42216 days, since 1st Jan 1900, How can I calculate that date? Answer is : 31-Jul-2015.
Try this:
(function(){
var date = new Date(1900,1,1);
var dayCount = 42216;
date.setDate(date.getDate() + dayCount)
console.log(date);
})()
Try this:
start = "01/01/1900"
newDate = start.split("/");
x = new Date(newDate[2]+"/"+newDate[1]+"/"+newDate[0]);
var numberOfDaysToAdd = 42216;
x.setDate(x.getDate() + parseInt(numberOfDaysToAdd));
var dd = x.getDate();
var mm = x.getMonth() + 1;
var yyyy = x.getFullYear();
var format = dd+'/'+mm+'/'+yyyy;
alert(format);
JSFIDDLE DEMO
Hope it help:
var dateStart= new Date('1900-01-01');
var afterDay=42216;
var newDay=new Date(dateStart.getTime() + afterDay*24*60*60*1000);
alert(newDay);

i get PST date formate from Database and i need to convert IST formate. But my system also in IST Formate. please check this http://jsfiddle.net/sfcdD/9/.
var date = "2012-12-12 05:18:28.541"; // PST date formate fetch from db
var offset = (3600000*(+5.30)); // IST gmtOffset value
var dateformate = 'dd/mm/yyyy "at" h:MM TT';
var dateArray = (date).split(' ');
var year = dateArray[0].split('-');
var time = dateArray[1].split(':');
var d = new Date($.trim(year[0]), $.trim(year[1]-1), $.trim(year[2]), $.trim(time[0]), $.trim(time[1]));
utc = d.getTime() +(d.getTimezoneOffset()*60000); //d.getTimezoneOffset() is taking local timezone
nd = new Date(utc + parseInt(offset));
alert(dateFormat(nd,dateformate)); // dispaly 12/12/2012 at 5:06 AM but need to display 12/12/2012 at 7:48 PM
so my conversion is not work. it display wrong date.
How about this?
var date = "2012-12-12 05:18:28.541";
var offset = (3600000*(+5.50+8));
var dateformate = 'dd/mm/yyyy "at" h:MM TT';

var year = dateArray[0].split('-');
var time = dateArray[1].split(':');
var d = new Date($.trim(year[0]), $.trim(year[1]-1), $.trim(year[2]), $.trim(time[0]), $.trim(time[1]));
var nd = new Date(d.getTime() + offset);
alert(dateFormat(nd,dateformate));
var offset = (3600000*(+5.30)); // IST gmtOffset value
should be
var offset = (3600000*(+5.50)); // IST gmtOffset value
