MomentJS not returning correct info - momentjs

I have an ISO formatted date that isn't being converted to the correct time, and I can't figure out why.
const m = (() => {
console.log("Here is the original time: " + periods)
const timeFixed = moment(periods).format("dddd, MMMM Do YYYY, h:mm:ss ");
console.log("Here is the fixed time: " + timeFixed)
return timeFixed;
})();
Using this, returns this:
Here is the original time: 2020-08-12T08:52:55Z
Here is the fixed time: Wednesday, January 1st 2020, 12:00:00
Any help given is appreciated as always.

Solved it, weirdly. It seems Moment was having an issue with the incoming format. Converted it to a string, then it handled it.
const m = (() => {
console.log("Here is the original time: " + periods)
const timeString = new Date(periods);
const timeFixed = moment(timeString).format("dddd, MMMM Do YYYY, hh:mm:ss ");
console.log("Here is the fixed time: " + timeFixed)
return timeFixed;
})();
Resulted in:
Here is the original time: 2020-08-12T08:52:55Z
Here is the fixed time: Wednesday, August 12th 2020, 09:52:55
Yes the time zone is off, but that's another problem for another day. Thanks for helping me find it.

momentjs won't get difference between two dates

I'm trying to get the difference between now and an end date in minutes. I have two date variables, but when i try to subtract them, it says Property 'diff' does not exist on type 'string'.
console.log(now) outputs: November 24th 2019, 11:13:32
console.log(endDate) outputs: November 24th 2019, 12:25:10
so the values are in date format.
I appreciate any help
let endDateTime = moment
.unix(parseInt(auctionEndDateTime))
.format("MMMM Do YYYY, h:mm:ss");
let start=moment(Date.now());
let end=moment(endDateTime);
let duration = moment.duration(end.diff(start));
let hours = duration.asHours();
console.log('hours ' + hours);
console.log('days ' + duration.asDays());
// you can get the difference between two days with javascript Date class
let firstDate = new Date('Sun Nov 24 2019 17:28:33'); //new Date('2019-11-12');
let secondDate = new Date('Tue Nov 26 2019 17:28:33');//new Date('2019-11-20');
let milliSFirst = firstDate.getTime();
let milliSSecond = secondDate.getTime();
console.log("diff in days " + (milliSSecond - milliSFirst)/(1000 * 3600 * 24) )
// take the dates as milliseconds and then you can do the calculations
let start=moment(Date.now());
let end=moment(Date.now() + 1000 * 3600 * 24 );
let duration = moment.duration(end.diff(start));
let hours = duration.asHours();
console.log('hours ' + hours);
console.log('days ' + duration.asDays());

Moment JS getting Date without time [duplicate]

formatCalendarDate = function (dateTime) {
return moment.utc(dateTime).format('LLL');
};
It displays: "28 februari 2013 09:24"
But I would like to remove the time at the end. How can I do that?
I'm using Moment.js.
Sorry to jump in so late, but if you want to remove the time portion of a moment() rather than formatting it, then the code is:
.startOf('day')
Ref: http://momentjs.com/docs/#/manipulating/start-of/
Use format('LL')
Depending on what you're trying to do with it, format('LL') could do the trick. It produces something like this:
Moment().format('LL'); // => April 29, 2016
The correct way would be to specify the input as per your requirement which will give you more flexibility.
The present definition includes the following
LTS : 'h:mm:ss A',
LT : 'h:mm A',
L : 'MM/DD/YYYY',
LL : 'MMMM D, YYYY',
LLL : 'MMMM D, YYYY h:mm A',
LLLL : 'dddd, MMMM D, YYYY h:mm A'
You can use any of these or change the input passed into moment().format().
For example, for your case you can pass moment.utc(dateTime).format('MMMM D, YYYY').
Okay, so I know I'm way late to the party. Like 6 years late but this was something I needed to figure out and have it formatted YYYY-MM-DD.
moment().format(moment.HTML5_FMT.DATE); // 2019-11-08
You can also pass in a parameter like, 2019-11-08T17:44:56.144.
moment("2019-11-08T17:44:56.144").format(moment.HTML5_FMT.DATE); // 2019-11-08
https://momentjs.com/docs/#/parsing/special-formats/
You can also use this format:
moment().format('ddd, ll'); // Wed, Jan 4, 2017
formatCalendarDate = function (dateTime) {
return moment.utc(dateTime).format('LL')
}
Look at these Examples.
Format Dates
moment().format('MMMM Do YYYY, h:mm:ss a'); // December 7th 2020, 9:58:18 am
moment().format('dddd'); // Monday
moment().format("MMM Do YY"); // Dec 7th 20
moment().format('YYYY [escaped] YYYY'); // 2020 escaped 2020
moment().format(); // 2020-12-07T09:58:18+05:30
Relative Time
moment("20111031", "YYYYMMDD").fromNow(); // 9 years ago
moment("20120620", "YYYYMMDD").fromNow(); // 8 years ago
moment().startOf('day').fromNow(); // 10 hours ago
moment().endOf('day').fromNow(); // in 14 hours
moment().startOf('hour').fromNow(); // an hour ago
Calendar Time
moment().subtract(10, 'days').calendar(); // 11/27/2020
moment().subtract(6, 'days').calendar(); // Last Tuesday at 9:58 AM
moment().subtract(3, 'days').calendar(); // Last Friday at 9:58 AM
moment().subtract(1, 'days').calendar(); // Yesterday at 9:58 AM
moment().calendar(); // Today at 9:58 AM
moment().add(1, 'days').calendar(); // Tomorrow at 9:58 AM
moment().add(3, 'days').calendar(); // Thursday at 9:58 AM
moment().add(10, 'days').calendar(); // 12/17/2020
Multiple Locale Support
moment.locale(); // en
moment().format('LT'); // 9:58 AM
moment().format('LTS'); // 9:58:18 AM
moment().format('L'); // 12/07/2020
moment().format('l'); // 12/7/2020
moment().format('LL'); // December 7, 2020
moment().format('ll'); // Dec 7, 2020
moment().format('LLL'); // December 7, 2020 9:58 AM
moment().format('lll'); // Dec 7, 2020 9:58 AM
moment().format('LLLL'); // Monday, December 7, 2020 9:58 AM
moment().format('llll'); // Mon, Dec 7, 2020 9:58 AM
Whenever I use the moment.js library I specify the desired format this way:
moment(<your Date goes here>).format("DD-MMM-YYYY")
or
moment(<your Date goes here>).format("DD/MMM/YYYY")
... etc I hope you get the idea
Inside the format function, you put the desired format. The example above will get rid of all unwanted elements from the date such as minutes and seconds
With newer versions of moment.js you can also do this:
var dateTime = moment();
var dateValue = moment({
year: dateTime.year(),
month: dateTime.month(),
day: dateTime.date()
});
See: http://momentjs.com/docs/#/parsing/object/.
You can use this constructor
moment({h:0, m:0, s:0, ms:0})
http://momentjs.com/docs/#/parsing/object/
console.log( moment().format('YYYY-MM-DD HH:mm:ss') )
console.log( moment({h:0, m:0, s:0, ms:0}).format('YYYY-MM-DD HH:mm:ss') )
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.22.2/moment.min.js"></script>
For people like me want the long date format (LLLL) but without the time of day, there's a GitHub issue for that: https://github.com/moment/moment/issues/2505. For now, there's a workaround:
var localeData = moment.localeData( moment.locale() ),
llll = localeData.longDateFormat( 'llll' ),
lll = localeData.longDateFormat( 'lll' ),
ll = localeData.longDateFormat( 'll' ),
longDateFormat = llll.replace( lll.replace( ll, '' ), '' );
var formattedDate = myMoment.format(longDateFormat);
Try this:
moment.format().split("T")[0]
The thing is - you can run into an issue with timezones. For example, if you parse date like this: '2022-02-26T00:36:21+01:00' it may turn into '25/02/2022' As a solution if your date is in ISO format you can just cut off the time portion from the string, like this:
moment('2022-02-26T00:36:21+01:00'.split('T')[0]).utc().format('DD/MM/YYYY')
This solution is quite blunt, so be careful with string format.
This format works pretty fine
const date = new Date();
const myFormat= 'YYYY-MM-DD';
const myDate = moment(date, 'YYYYMMDDTHHmmss').format(myFormat);
Try
new Date().toDateString()
Result - "Fri Jun 17 2022"
This worked perfectly for me:
moment().format('YYYY-MM-DD')
moment(date).format(DateFormat)
Here DateFormat should be DateFormat = 'YYYY-MM-DD'

Getting one hour less in time when converting to UTC via moment - utcOffset not working

When converting time to UTC its showing one hour less than expected
I am updating a variable of dot net via moment to convert the time & show local system time to user. But post conversion i am getting one hour less. Tried utcOffset but getting error utcOffset is not a function. any suggestion
Where formData.SubmittedDate = "6/7/2019 5:44:59 AM"
$('[data-utcdate]').each(function () {
var d = moment($(this).attr('data-utcdate'));
//var isDST = d.utc().local().isDST();
//var d = moment(d).utcOffset(d);
d = d.utc();
$(this).html(d.format('MMM D, YYYY h:mm A'));
})
Getting :Jun 7, 2019 12:14 AM
Expected : Jun 7, 2019 11:44 AM
From the docs:
Get the UTC offset in minutes.
So you could use a manipulation method like add with it:
$('[data-utcdate]').each(function () {
var d = moment($(this).attr('data-utcdate'));
var offset = d.utcOffset() // will return the offset in minutes
var time = d.add(offset, "m");
$(this).html(time.format('MMM D, YYYY h:mm A'));
})

Why moment.js adds 3 minutes to a date-time when its formatted?

When I'm formatting the date-time with moment.js, I got a strange behavior. It adds 3 minutes to the date-time.
Without specific formatting there is 08:00
moment("2018-03-25T06:00:00Z").format()
"2018-03-25T08:00:00+02:00"
But if I format the date-time, I got 08:03
moment("2018-03-25T06:00:00Z").format("YYYY/MM/DD HH:MM")
"2018/03/25 08:03"
Why is that?
const withoutFormat = moment("2018-03-25T06:00:00Z").format();
const withFormat = moment("2018-03-25T06:00:00Z").format("YYYY/MM/DD HH:MM");
console.log(withoutFormat);
console.log(withFormat);
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.20.1/moment.js"></script>
Change HH:MM to HH:mm because MM is used for months in momentjs
const withoutFormat = moment("2018-03-25T06:00:00Z").format();
const withFormat = moment("2018-03-25T06:00:00Z").format("YYYY/MM/DD HH:mm");
console.log(withoutFormat);
console.log(withFormat);
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.20.1/moment.js"></script>
Its just because MM gives month number. if you want 12 hour use h/hh , for 24 hour H/HH and minute m/mm. Here is doc
const withoutFormat = moment("2018-03-25T06:00:00Z").format();
const withFormat = moment("2018-03-25T06:00:00Z").format("YYYY/MM/DD hh:mm");
console.log(withoutFormat);
console.log(withFormat);

Getting the month number by month name with Moment.js

I am trying to return the month number passing the month name using MomentJS. For example if I pass "July" to moment() I would expect 7 to be returned.
After reading through the docs I tried several different ways, and this way came close...
console.log(moment().month("July"));
In the console, buried in the response I could see this...
_monthsParse: Array[7]
Could anyone please tell me how to return the month number using MomentJS correctly?
Try :
moment().month("July").format("M");
Relevant documentation: http://momentjs.com/docs/#/get-set/month/
alert(moment().month("July").format("M"));
<script src="https://momentjs.com/downloads/moment.min.js"></script>
Anybody looking to get month name from month number then you can try :
const number = 1; // 0 = Jan & 11 = Dec
moment().month(number).format("MMM"); // Feb
Use following to get full month name :
const number = 1; // 0 = January & 11 = December
moment().month(number).format("MMMM"); // February
To use simple month number try this:
const month = 2 //Feb
moment(month, 'M').format('MMMM');
##get month name in moment js with node js
moment() give today date
format("DD-MMMM-YYYY") / output 18-May-2020
format("DD-MM-YYYY") / output 18-05-2020
- sperator you can use /
```
var moment = require('moment');
m_date = moment().format("DD-MMMM-YYYY");
console.log("moment date :", m_date)
```
##output
```
moment date : 18-May-2020
```
