JavaScript - subtract minutes from date
0 points
In this article, we would like to show you how to subtract minutes from date in JavaScript.
Quick solution:
xxxxxxxxxx1
const date = new Date('2021-06-30T00:00:00.000Z');2
3
date.setMinutes(date.getMinutes() - 2); // subtracted 2 minutes from existing date4
5
console.log(date.toISOString()); // 2021-06-29T23:58:00.000Z
In this example, we create a simple function that takes two arguments:
datefrom which we want to subtract some minutes,minutes- a number of minutes we want to subtract.
Runnable example:
xxxxxxxxxx1
const subtractMinutes = (date, minutes) => {2
const result = new Date(date);3
result.setMinutes(result.getMinutes() - minutes);4
return result;5
};6
7
let date = new Date('2021-06-30T00:00:00.000Z');8
9
console.log(subtractMinutes(date, 2).toISOString());Output:
xxxxxxxxxx1
2021-06-29T23:58:00.000ZNote:
As you can see, the function also handles the case of the day change.
In this example, we add a function to the Date.prototype so we can use it on any date object.
xxxxxxxxxx1
Date.prototype.subtractMinutes = function (minutes) {2
let date = new Date(this.valueOf());3
date.setMinutes(date.getMinutes() - minutes);4
return date;5
};6
7
let date = new Date('2021-06-30T00:00:00.000Z');8
9
console.log(date.subtractMinutes(2).toISOString());Output:
xxxxxxxxxx1
