JavaScript - Get minutes between two dates

Question

If I have two dates, how can I use JavaScript to get the difference between the two dates in minutes?

Answer 1

A simple function to perform this calculation:

function getMinutesBetweenDates(startDate, endDate) {
    var diff = endDate.getTime() - startDate.getTime();
    return (diff / 60000);
}

Answer 2

That's should show the difference between the two dates in minutes.

const currDate = new Date('Tue Feb 13 2018 13:04:58 GMT+0200 (EET)')
const oldDate  = new Date('Tue Feb 13 2018 12:00:58 GMT+0200 (EET)')

(currDate - oldDate) / 60000 # 64.0026

Answer 3

You may checkout this code:

var today = new Date();
var Christmas = new Date("12-25-2012");
var diffMs = (Christmas - today); // milliseconds between now & Christmas
var diffDays = Math.floor(diffMs / 86400000); // days
var diffHrs = Math.floor((diffMs % 86400000) / 3600000); // hours
var diffMins = Math.round(((diffMs % 86400000) % 3600000) / 60000); // minutes
alert(diffDays + " days, " + diffHrs + " hours, " + diffMins + " minutes until Christmas 2009 =)");

or var diffMins = Math.floor((... to discard seconds if you don't want to round minutes.

Answer 4

This problem is solved easily with moment.js, like this example:

var difference = mostDate.diff(minorDate, "minutes");

The second parameter can be changed for another parameters, see the moment.js documentation.

e.g.: "days", "hours", "minutes", etc.

The CDN for moment.js is available here:

Thanks.

EDIT:

mostDate and minorDate should be a moment type.

Answer 5

Here's some fun I had solving something similar in node.

function formatTimeDiff(date1, date2) {
  return Array(3)
    .fill([3600, date1.getTime() - date2.getTime()])
    .map((v, i, a) => {
      a[i+1] = [a[i][0]/60, ((v[1] / (v[0] * 1000)) % 1) * (v[0] * 1000)];
      return `0${Math.floor(v[1] / (v[0] * 1000))}`.slice(-2);
    }).join(':');
}

const millis = 1000;
const utcEnd = new Date(1541424202 * millis);
const utcStart = new Date(1541389579 * millis);
const utcDiff = formatTimeDiff(utcEnd, utcStart);

console.log(`Dates:
  Start   : ${utcStart}
  Stop    : ${utcEnd}
  Elapsed : ${utcDiff}
  `);

/*
Outputs:

Dates:
  Start   : Mon Nov 05 2018 03:46:19 GMT+0000 (UTC)
  Stop    : Mon Nov 05 2018 13:23:22 GMT+0000 (UTC)
  Elapsed : 09:37:02
*/

Answer 6

Subtracting 2 Date objects gives you the difference in milliseconds, e.g.:

var diff = Math.abs(new Date('2011/10/09 12:00') - new Date('2011/10/09 00:00'));

Math.abs is used to be able to use the absolute difference (so new Date('2011/10/09 00:00') - new Date('2011/10/09 12:00') gives the same result).

Dividing the result by 1000 gives you the number of seconds. Dividing that by 60 gives you the number of minutes. To round to whole minutes, use Math.floor or Math.ceil:

var minutes = Math.floor((diff/1000)/60);

In this example the result will be 720
