Get the time difference between two datetimes

Question

I know I can do anything and some more envolving Dates with momentjs. But embarrassingly, I\'m having a hard time trying to do something that seems simple: geting the differ

Answer 1

The following approach is valid for all cases (difference between dates less than 24 hours and difference greater than 24 hours):

// Defining start and end variables
let start = moment('04/09/2013 15:00:00', 'DD/MM/YYYY hh:mm:ss');
let end   = moment('04/09/2013 14:20:30', 'DD/MM/YYYY hh:mm:ss');

// Getting the difference: hours (h), minutes (m) and seconds (s)
let h  = end.diff(start, 'hours');
let m  = end.diff(start, 'minutes') - (60 * h);
let s  = end.diff(start, 'seconds') - (60 * 60 * h) - (60 * m);

// Formating in hh:mm:ss (appends a left zero when num < 10)
let hh = ('0' + h).slice(-2);
let mm = ('0' + m).slice(-2);
let ss = ('0' + s).slice(-2);

console.log(`${hh}:${mm}:${ss}`); // 00:39:30

Answer 2

var a = moment([2007, 0, 29]);
var b = moment([2007, 0, 28]);
a.diff(b, 'days') //[days, years, months, seconds, ...]
//Result 1 

Worked for me

Answer 3

This should work fine.

var now  = "04/09/2013 15:00:00";
var then = "02/09/2013 14:20:30";

var ms = moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"));
var d = moment.duration(ms);

console.log(d.days() + ':' + d.hours() + ':' + d.minutes() + ':' + d.seconds());

Answer 4

EPOCH TIME DIFFERENCE USING MOMENTJS:

To Get Difference between two epoch times:

Syntax: moment.duration(moment(moment(date1).diff(moment(date2)))).asHours()

Difference in Hours: moment.duration(moment(moment(1590597744551).diff(moment(1590597909877)))).asHours()

Difference in minutes: moment.duration(moment(moment(1590597744551).diff(moment(1590597909877)))).asMinutes().toFixed()

Note: You could remove .toFixed() if you need precise values.

Code:

const moment = require('moment')

console.log('Date 1',moment(1590597909877).toISOString())
console.log('Date 2',moment(1590597744551).toISOString())
console.log('Date1 - Date 2 time diffrence is : ',moment.duration(moment(moment(1590597909877).diff(moment(1590597744551)))).asMinutes().toFixed()+' minutes')

Answer 5

This will work for any date in the format YYYY-MM-DD HH:mm:ss

const moment=require("moment");
let startDate=moment("2020-09-16 08:39:27");
const endDate=moment();


const duration=moment.duration(endDate.diff(startDate))
console.log(duration.asSeconds());
 console.log(duration.asHours());

Answer 6

Instead of

Math.floor(duration.asHours()) + moment.utc(duration.asMilliseconds()).format(":mm:ss")

It's better to do

moment.utc(total.asMilliseconds()).format("HH:mm:ss");
