Moment.js: Subtracting Time from a Date

To subtract time from a given date with moment.js, just follow the steps below:

1. Create a moment object with your date:

const date = moment('2022-15-09 13:30:45');

2. Construct a duration object from your time string with the moment.duration() method:

const duration = momment.duration('9:15:30');

3. Invoke the subtract() method on the moment object with the argument is the duration object created in the previous step:

const result = date.substract(duration);

Let’s examine a couple of examples below for more clarity.

Example 1

import moment from 'moment';

const dateOne = moment('2023-02-19 19:00:05');
const durationOne = moment.duration('13:30:45');
const resultOne = dateOne.subtract(durationOne);
console.log(resultOne.format('YYYY-MM-DD HH:mm:ss'));

Output:

2023-02-19 05:29:20

Example 2

import moment from 'moment';

const dateTwo = moment('2029-12-30 05:19:05');
const durationTwo = moment.duration({
    year: 10,
    month: 2,
    day: 3,
    hour: 4,
    minute: 5,
    second: 6,
  });
const resultTwo = dateTwo.subtract(durationTwo);
console.log(resultTwo.format('YYYY-MM-DD HH:mm:ss'));

Output:

2019-10-27 01:13:59
