I need to get the start date and end date in the below format using moment js
startDate = 20160427000000 and
endDate = 20160427235959
Here the start date appended with 000000 and end date appended with 235959
What is the right way to get this result in javascript
You want the format operator. Since it looks like your 0's and 2359's are hardcoded (I assume you're doing start and end of days), try:
startDate = moment().format('YMMDD000000');
endDate = moment().format('YMMDD235959');
EDIT: Or, as RobG pointed out, you can use:
startDate = moment().startOf('day').format("YMMDDHHmmss");
endDate = moment().endOf('day').format("YMMDDHHmmss");
(Which is much neater)
I'm totally confused, I don't know if you want to parse the format or output it. If you want to parse dates using moment.js in that format, then in time zone +05:30:
// Format YYYYMMDDHHmmss for 2016-04-26T00:00:00
var s = '20160426000000';
var x = moment(s, 'YYYYMMDDHHmmss');
// Show date in ISO 8601 extended format
console.log(x.format()); // 2016-04-26T00:00:00+05:30
To shift to the end of the day and output in YYYMMDDHHmmss format:
console.log(x.endOf('day').format('YYYYMMDDHHmmss')); // 20160426235959
In the format string:
YYYY is 4 digit year
MM is two digit month
DD is two digit day
HH is two digit hour in 24 hour format
mm is two digit minute
ss is two digit seconds
For Getting Format Like these in moment.js - (2020-12-15T13:00:00)
let a =2023-01-14T20:15:00-05:00
You can use moment(a).format("YYYY-MM-DDTHH:mm:ss")
Result: 2023-01-14T20:15:00

When I want to convert the Gregorian date to Persian date, it converts the value of the minute in the date conversion to error.
For example I want to convert this date time to Persian date:
2020-09-14T16:51:00+04:30 must convert to this 1399/06/24 16:51 but when convert date it show me this time 1399/06/24 00:06 it mistake to convert 16:51, show this: 00:06.
This is my code to convert date:
toPersianDate(date: any, format = 'YYYY/MM/DD HH:MM'): string {
let dateTime;
const MomentDate = moment(date, 'YYYY/MM/DD');
dateTime = MomentDate.locale('fa').format('jYYYY/jMM/jDD HH:jMM');
return dateTime;
}
What's the problem? How can I solve this problem?
the MM is used for month formatting, so it is trying to format the minutes into a month.
What you need to use is the small mm. Moreover, I don't this you need the j before the mm as the minutes are the same in Jalali time.
So what you actually need is this: MomentDate.locale('fa').format('jYYYY/jMM/jDD HH:mm');
You can read more about the formatting here.
Hi i have been working on the final question for my assignment and i have to check if today's date is greater than a date that is store as a number in a database. ie today's date would be 16122017 dd mm yy as you can see it has no spaces or a "-" or "/" just a number. i can get todays date reverse it and remove the - but a simple < or > does not work for comparison as they are numbers not java date formats.
So i figure i have to add the - back into the date and reverse it so it yy mm dd and then compare it to the current date.
Can any one show me how to add - into the number format, i can simply reverse it back to yy mm dd from dd mm yy once done with
> c = c.split('-').reverse().join('');
where c is the var containing the number date. i assume once it has - back in it i could just do
if (c > LocalDate.now())
or do i need to assign it to a new date var ?
There are some cool addon packages like moment.js that can do this with an elegant call. But, in native javascript you can do this sort of thing, using the handy-dandy setFullYear(y,m,d) function.
var ds = '16122017'
var myDate = new Date();
myDate.setFullYear(ds.substring(4,8),ds.substring(2,4)-1,ds.substring(0,2));
var today = new Date();
today.setHours (0,0,0,0); /* turn now into today */
if (myDate < today) {
/* myDate was before today */
}
Besides using a library that can convert the dates for you, I suggest the good old substring method if you know for sure that the first two numbers are the day, then month, then year, such that
var day = str.substring(1, 2);
and so on. Then you create a new Date object based on your calculations and work with it.
If your input doesn't have trailing zeros, that adds complexity to the problem, but nothing that you can't overcome.
I have a date in the following format var timestamp = "6/9/2016 1:47:31 PM";. I'm trying to get the relative time (4 hours ago, 3 minutes ago, 3 days ago, etc...) from the timestamp compared to the current datetime using from now.
var LastReading = moment(timestamp).fromNow();
but this is returning "2010 years from now". I tried using the format
var LastReading = moment(timestamp, "MM/DD/YYYY HH:mm:ss").fromNow();
but I get the same result. Any ideas? Do I need to format the date in a different way in order to get the fromNow method to work as expected?
To match your timestamp, the format should look like this:
MM/DD/YYYY hh:mm:ss A
HH means 24 hour time, but you're using 12 hour time, for which you need to use hh. Also, A will match AM/PM.
I need to convert date to Java epoch and then read it and convert back. Not sure what I'm doing wrong here?
var date = new Date('1/3/2013');
var timeStamp = date.getTime();
console.log(timeStamp);
var revertDate = new Date(timeStamp);
console.log(revertDate.getDate()+'/'+revertDate.getMonth()+'/'+revertDate.getFullYear());
The output is 3/0/2013 instad 1/3/2013?

You've got two problems here:
The Date constructor is assuming M/d/yyyy format - whereas you're logging d/M/yyyy format. Personally I'd suggest using an ISO-8601 format if at all possible: yyyy-MM-dd
You're not taking into account the fact that getMonth() returns a 0-based value
For the formatting side, you'd be better off using toISOString or something similar, rather than doing the formatting yourself.
(Note that looking at the documentation for the Date constructor it's not clear that the code you've got should work at all, as it's neither an RFC822 nor ISO-8601 format.)
Neither of the problems are to do with converting between Date and a numeric value. If you change your logging, you'll see that clearly:
var date = new Date('1/3/2013');
var timeStamp = date.getTime();
console.log(date);
var revertDate = new Date(timeStamp);
console.log(revertDate);
var date = new Date('1/3/2013');
The Date constructor is parsing this given string this way:
Month / Day / Year
So, in this case, Month is 1, Day is 3 and Year is 2013. What's going on there? Well that's quite simple. This Gregorian representation of a date(which is specifically Day / Month / Year ) isn't the one used by the Date constructor, so it will parse the 1(the month) as January, the 3 as the third day of the month(the third of Jan) and the year correctly, the 2013. Now, due to its 0-based indexing, the constructed Date object will return a month which is n-1 among the one provided. That's why you're getting 3/0/2013. It is the third day(3) of the month 0(which is January) of 2013. If you want to get your real date you have to do this:
var date = new Date('3/1/2013');
console.log(date.getDate()+'/'+(date.getMonth()+1)+'/'+date.getFullYear());
I have a senario where i have to parse two dates for example start date and end date.
var startdate = '02/01/2011';
var enddate = '31/12/2011';
But if we alert start date
alert(Date.Parse(startdate)); i will get 1296498600000
but if i alert enddate
alert(Date.Parse(enddate)); i will get NaN
But this is working in other browsers except Chrome, But in other browsers
alert(Date.Parse(enddate)); i will get 1370889000000
Can anybody know a workaround for this?
If you want to parse a date without local differences, use the following, instead of Date.parse():
var enddate = '31/12/2011'; //DD/MM/YYYY
var split = enddate.split('/');
// Month is zero-indexed so subtract one from the month inside the constructor
var date = new Date(split[2], split[1] - 1, split[0]); //Y M D
var timestamp = date.getTime();

According to this
dateString
A string representing an RFC822 or ISO 8601 date.
I've tried your code and I also get NaN for the end date, but if i swap the date and month around, it works fine.
