I want to convert date to timestamp, my input is 26-02-2012. I used
new Date(myDate).getTime();
It says NaN.. Can any one tell how to convert this?
Split the string into its parts and provide them directly to the Date constructor:
Update:
var myDate = "26-02-2012";
myDate = myDate.split("-");
var newDate = new Date( myDate[2], myDate[1] - 1, myDate[0]);
console.log(newDate.getTime());
Try this function, it uses the Date.parse() method and doesn't require any custom logic:
function toTimestamp(strDate){
var datum = Date.parse(strDate);
return datum/1000;
}
alert(toTimestamp('02/13/2009 23:31:30'));
this refactored code will do it
let toTimestamp = strDate => Date.parse(strDate)
this works on all modern browsers except ie8-
There are two problems here.
First, you can only call getTime on an instance of the date. You need to wrap new Date in brackets or assign it to variable.
Second, you need to pass it a string in a proper format.
Working example:
(new Date("2012-02-26")).getTime();
UPDATE: In case you came here looking for current timestamp
Date.now(); //as suggested by Wilt
or
var date = new Date();
var timestamp = date.getTime();
or simply
new Date().getTime();
/* console.log(new Date().getTime()); */
You need just to reverse your date digit and change - with ,:
new Date(2012,01,26).getTime(); // 02 becomes 01 because getMonth() method returns the month (from 0 to 11)
In your case:
var myDate="26-02-2012";
myDate=myDate.split("-");
new Date(parseInt(myDate[2], 10), parseInt(myDate[1], 10) - 1 , parseInt(myDate[0]), 10).getTime();
P.S. UK locale does not matter here.
To convert (ISO) date to Unix timestamp, I ended up with a timestamp 3 characters longer than needed so my year was somewhere around 50k...
I had to devide it by 1000:
new Date('2012-02-26').getTime() / 1000
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())));
}
For those who wants to have readable timestamp in format of, yyyymmddHHMMSS
> (new Date()).toISOString().replace(/[^\d]/g,'') // "20190220044724404"
> (new Date()).toISOString().replace(/[^\d]/g,'').slice(0, -3) // "20190220044724"
> (new Date()).toISOString().replace(/[^\d]/g,'').slice(0, -9) // "20190220"
Usage example: a backup file extension. /my/path/my.file.js.20190220
Your string isn't in a format that the Date object is specified to handle. You'll have to parse it yourself, use a date parsing library like MomentJS or the older (and not currently maintained, as far as I can tell) DateJS, or massage it into the correct format (e.g., 2012-02-29) before asking Date to parse it.
Why you're getting NaN: When you ask new Date(...) to handle an invalid string, it returns a Date object which is set to an invalid date (new Date("29-02-2012").toString() returns "Invalid date"). Calling getTime() on a date object in this state returns NaN.
JUST A REMINDER
Date.parse("2022-08-04T04:02:10.909Z")
1659585730909
Date.parse(new Date("2022-08-04T04:02:10.909Z"))
1659585730000
/**
* Date to timestamp
* #param string template
* #param string date
* #return string
* #example datetotime("d-m-Y", "26-02-2012") return 1330207200000
*/
function datetotime(template, date){
date = date.split( template[1] );
template = template.split( template[1] );
date = date[ template.indexOf('m') ]
+ "/" + date[ template.indexOf('d') ]
+ "/" + date[ template.indexOf('Y') ];
return (new Date(date).getTime());
}
The below code will convert the current date into the timestamp.
var currentTimeStamp = Date.parse(new Date());
console.log(currentTimeStamp);
The first answer is fine however Using react typescript would complain because of split('')
for me the method tha worked better was.
parseInt((new Date("2021-07-22").getTime() / 1000).toFixed(0))
Happy to help.
In some cases, it appears that some dates are stubborn, that is, even with a date format, like "2022-06-29 15:16:21", you still get null or NaN. I got to resolve mine by including a "T" in the empty space, that is:
const inputDate = "2022-06-29 15:16:21";
const newInputDate = inputDate.replace(" ", "T");
const timeStamp = new Date(newInputDate).getTime();
And this worked fine for me! Cheers!
It should have been in this standard date format YYYY-MM-DD, to use below equation. You may have time along with example: 2020-04-24 16:51:56 or 2020-04-24T16:51:56+05:30. It will work fine but date format should like this YYYY-MM-DD only.
var myDate = "2020-04-24";
var timestamp = +new Date(myDate)
You can use valueOf method
new Date().valueOf()
a picture speaks a thousand words :)
Here I am converting the current date to timestamp and then I take the timestamp and convert it to the current date back, with us showing how to convert date to timestamp and timestamp to date.
The simplest and accurate way would be to add the unary operator before the date
console.log(`Time stamp is: ${Number(+new Date())}`)
Answers have been provided by other developers but in my own way, you can do this on the fly without creating any user defined function as follows:
var timestamp = Date.parse("26-02-2012".split('-').reverse().join('-'));
alert(timestamp); // returns 1330214400000
Simply performing some arithmetic on a Date object will return the timestamp as a number. This is useful for compact notation. I find this is the easiest way to remember, as the method also works for converting numbers cast as string types back to number types.
let d = new Date();
console.log(d, d * 1);
This would do the trick if you need to add time also
new Date('2021-07-22 07:47:05.842442+00').getTime()
This would also work without Time
new Date('2021-07-22 07:47:05.842442+00').getTime()
This would also work but it won't Accept Time
new Date('2021/07/22').getTime()
And Lastly if all did not work use this
new Date(year, month, day, hours, minutes, seconds, milliseconds)
Note for Month it the count starts at 0 so Jan === 0 and Dec === 11
+new Date(myDate)
this should convert myDate to timeStamp
I have a date string like this 20/09/2018 12:00 AM. I need to stop to put the previous date than today. I have searched the web for it, but no answer found with this format.
I need the default date format of JavaScript so that I can compare with new Date() value. When I use the following format it show the message that says invalid date because of my dd/MM/yyyy hh:mm tt format.
alert(new Date("20/09/2018 12:00 AM"));
Igor recommended using moment.js to solve this — it is a widely used date/time library.
With moment.js you can do this:
var m = moment("20/09/2018 3:14 PM", "DD/MM/YYYY h:mm a");
var d = m.toDate();
The first line creates a "moment" object by parsing the date according to the format string specified as the second argument. See http://momentjs.com/docs/#/parsing/
The second line gets the native javascript Date object that the moment object encapsulates; however, moment can do so many things you may not need to get back that native object.
See the moment docs.
Your format isn't valid, thus you're getting invalid date error. So, using your format(dd/MM/yyyy hh:mm tt) we'll grab the year, month, day, hours and the minutes, then we'll reformat it as an acceptable format by the Date constructor and create a Date instance.
Here's a function that do all what being said and returns a Date instance which you can compare it with another Date instance:
function convertToDate(str) {
// replace '/' with '-'
str = str.replace(/\//ig, '-');
/**
* extracting the year, month, day, hours and minutes.
* the month, day and hours can be 1 or 2 digits(the leading zero is optional).
* i.e: '4/3/2022 2:18 AM' is the same as '04/03/2022 02:18 AM' => Notice the absence of the leading zero.
**/
var y = /\-([\d]{4})/.exec(str)[1],
m = /\-([\d]{2}|[\d])/.exec(str)[1],
d = /([\d]{2}|[\d])\-/.exec(str)[1],
H = /\s([\d]{2}|[\d]):/.exec(str)[1],
i = /:([\d]{2})/.exec(str)[1],
AMorPM = /(AM|PM)/.exec(str)[1];
// return a Date instance.
return new Date(y + '-' + m + '-' + d + ' ' + H + ':' + i + ' ' + AMorPM)
}
// testing...
var str1 = '20/09/2018 12:00 AM';
var str2 = '8/2/2018 9:00 PM'; // leading zero is omitted.
console.log(convertToDate(str1));
console.log(convertToDate(str2));
The Date depends on the user's/server's location, two users may have
different results.

Javascript:I have a function which has s parameter s contains this s=07:05:45PM;s has time which is in form of string i want to use it in new Date() but gives error i had to get hours mins seconds convert this time to 24 hour format please help me output:invalid date
function time Conversion(s) {
var date=new Date(s);
console.log(date);
}
According to specification, you can pass the dateString as a parameter to the Date constructor. There is a bunch of dateString format limitations, and in you case your dateString (named s) is invalid for date constructor (actually, your s is even has not any date, it consists of time only).
The possible solution is to handle your s parameter manually: cut verbal part, split time by :, then pass params to the Date constructor in sequence year, month, date, hours, minutes, seconds, or construct your own ISO String, format:
{year}-{month}-{date}T{hours}:{minutes}:{seconds}.{milliseconds}Z
Note, that hours in both cases should be in 24-hours format, so you should manually handle your 12-h formatted hours.
The reason you're getting an invalid Date from the built-in parser is covered by Why does Date.parse give incorrect results?
To convert a string like 07:05:45PM to 24 hour time, you can parse the parts and generate an new string, adding 12 to the hour if it ends in PM or not if it ends in AM (and change 12am to 00). e.g.
function to24HrFormat(s) {
var z = n => (n<10?'0':'')+n;
var b = s.match(/\d+/g);
var ap = /am$/i.test(s)? 0 : 12;
return z((b[0]%12) + ap) + ':' + b[1] + ':' + b[2];
}
// Tests
['07:05:45PM', '06:23:49AM', '12:15:00AM', '11:59:59pm']
.forEach(s => console.log(s + ' => ' + to24HrFormat(s)));
You should validate the input string, and maybe allow for missing seconds.
From the time string, remove the AM/PM (need to have a 24hr timestring)
var time = "07:05:45";
var datetime = new Date('1970-01-01T' + time + 'Z');
Now do your time based operations.
Try using Date.parse(string) instead. See referene.
From Server I get Date in UTC format like ,
2016-04-13T02:37:13.211316121-04:00
When I use this to display using new Date(data.Created_at) I get 7 min time difference. Like as I am displaying my date in format {{my_date | date: 'h:mm a'}}, insted showing 12:05 PM, it dispalys 11:58 AM. So I tried this,
data.Created_at = new Date(Date.UTC(data.Created_at))
which returns null value. Is there any problem in my code? How should I get perfect date?
If you check syntax of Date.UTC,
Date.UTC(year, month[, day[, hour[, minute[, second[, millisecond]]]]])
It expects value in different variables and not in date string. You can split it and manually parse it.
You can try something like this:
JSFiddle
var d = "2016-04-13T02:37:13.211316121-04:00";
var date_arr = d.split(/[-|T|\.|:]/);
var o = new Date(Date.UTC(date_arr[0], date_arr[1], date_arr[2], date_arr[3], date_arr[4], date_arr[5]));
console.log(date_arr, o);
Also, it gives me 8:07 AM, considering the time is 2:37 and my timezone is +5:30.
Use it like this
Date.UTC(year,month,day,hours,minutes,seconds,millisec)
The code you are using is invalid way to handle date. You can use this code
new Date('2016-04-13T02:37:13.211316121-04:00').toISOString();
var created_at = new Date(createdAt);
var created_at_date = (created_at.getUTCMonth()+1) + "/" + created_at.getUTCDate() + "/" + created_at.getUTCFullYear() + "/" + created_at.getHours() + ":"
+ created_at.getMinutes() + ":" + created_at.getSeconds();
Hope this will work for you!!!
can i get help coverting this string to date format.
Here is the JSon name and value
notBefore: 1413936000000
notAfter: 1479427199000
I believe this needs to be converted to US format date mm/dd/yyyy
The callback string looks like this:
response.endpoints[0].details.cert.notBefore
response.endpoints[0].details.cert.notAfter
Just go ahead and craft up a new Date
new Date(notBefore)
If your values are indeed strings, you can parseInt() them
JSFiddle Example
If you need a simple example for mm/dd/yyyy format, here is a working fiddle to get you up and running.
var notBefore = 1413936000000;
var date = new Date(notBefore);
var formattedDate = (date.getMonth() + 1) + '/' + date.getDate() + '/' + date.getFullYear();
