datetime - Javascript Convert Date Time string to Epoch - Stack Overflow

so I give up...been trying to do this all day;

I have a string that supplies a date and time in the format dd/MM/yyyy hh:mm (04/12/2012 07:00).

I need to turn that into an Epoch date so I can do some calculations upon it. I cannot modify the format in which the date time is sent to me.

JavaScript or jQuery is fine.

• 1 new Date('04/12/2012 07:00')? – gen_Eric Commented Dec 4, 2012 at 16:30
• 1 Thanks Rocket, but that would give me April 12th and I want Dec 4th. – cbm64 Commented Dec 4, 2012 at 16:49

• uhhhh.... @cbm64 you mean new Date('12/04/2012 07:00') . ...? – John Commented Oct 15, 2019 at 21:37
• @cbm64 Hi, I'm facing the same issue. But in my case I only have date not time. New Date for mm/dd/yyyy is working, but I want to use dd/mm/yyyy . If it is new Date(dd/mm/yyyy) giving invalid date. Could you pls pls tell me how did you resolve it? – sai Commented May 23, 2020 at 3:25

var someDate = new Date(dateString);
someDate = someDate.getTime();

You can use Date.parse(date).

function epoch (date) {
  return Date.parse(date)
}

const dateToday = new Date() // Mon Jun 08 2020 16:47:55 GMT+0800 (China Standard Time)
const timestamp = epoch(dateToday)

console.log(timestamp) // => 1591606075000

JavaScript dates are internally stored as milliseconds since epoch. You just need to convert it to a number, e.g. with the unary + operator, to get them. Or you can use the .getTime method.

The harder will be parsing your date string. You likely will use a regex to extract the values from your string and pass them into Date.UTC:

var parts = datestring.match(/(\d{2})\/(\d{2})\/(\d{4}) (\d{2}):(\d{2})/);
return Date.UTC(+parts[3], parts[2]-1, +parts[1], +parts[4], +parts[5]);

This will yield 1354604400000 ms for your example date.

You can use the momentjs library to do this rather easily.

var epoch = moment(str).unix();

http://momentjs.com/

i used this code to convert my string datetime to epoch

new Date(<datetime string>').getTime()

for example :

let epoch = new Date('2016-10-11').getTime()

Number(new Date('04/12/2012 07:00'))

var time = new Date().getTime() / 1000 + 900 + 330*60;

console.log("time = "+time);

getTime() will return current time with milleseconds in last 3 digit so divide it by 1000 first. Now I have added 900 means 15 min which I need from my current time(You can delete if you do not require further delay time), 330*60(5 hr 30) is required to convert GMT time to IST which is my current region time.

Use below site to test your time :-

Hope it will help you :)

Since your date format is dd/MM/yyyy hh:mm, you will need to change the date format (Step 1). Else you can go to (Step 2).

Step 1. Change Date Format to MM/dd/yyyy hh:mm

  var currentTime   = "21/02/2021 12:00"
  var monthPosition = currentTime.split('/', 2).join('/').length
  var day           = currentTime.substring(0, currentTime.indexOf('/'))
  var month         = currentTime.substring(currentTime.indexOf('/') + 1, monthPosition);
  var time          = month + "/" + day + currentTime.substring(month.length + day.length  + 1); //"02/21/2021 12:00"

Step 2: Change Date to Epoch Time

var epochTime = Date.parse(time);

//or get current time of epoch time
var currentEpoch = Date.parse(new Date());

Note: If you trying to do Date.parse() with new Date(), and got an error of parsing date string, add toString()

var currentEpoch = Date.parse(new Date().toString());

My answer is to convert current time to epoch time using JavaScript

const currentDate = Math.floor(new Date() / 1000);

console.log(currentDate); //whatever value it will print you can check the same value to this website https://www.epochconverter.com/ to confirm.

I found this line from jslint code.

https://github.com/jslint-org/jslint/blob/a286a254f3312108cf64553914b99a642af0ac42/asset_codemirror_rollup.js#L268

+new Date

It's pretty obvious that this is Douglas Crockford way.

Easiest way to do is -

const moment = require('moment')


 function getUnixTime () { return this.getTime() / 1000 | 0 }
let epochDateTime = getUnixTime(new Date(moment().add(365, 'days').format('YYYY- 
MM-DD hh:mm:ss')))  

Single Line Code Returns in seconds

let Epoch= Date.parse(date + '') / 1000 //date in Date() Format

This is how I would do it

Math.trunc(new Date(date).getTime()/1000)

result

1671878316

const myDate = new Date("2023-04-15"); // create a new Date object with a specified date
const epochTime = myDate.getTime() / 1000; // divide by 1000 to convert milliseconds to seconds
console.log(epochTime); // output: 1687974000 (the epoch time for the specified date)

In this example, we first create a new Date object with a specified date using the new Date() constructor. We then call the getTime() method on the myDate object to get the time in milliseconds since the Unix epoch (January 1, 1970). Finally, we divide the result by 1000 to convert it to seconds, which is the format commonly used for epoch time.
