JavaScript - add months to date
0 points
In this article, we would like to show you how to add months to date in JavaScript.
In this example, we create a simple function that takes two arguments:
dateto which we want to add some months,months- a number of months we want to add.
Runnable example:
xxxxxxxxxx1
const addMonths = (date, months) => {2
let result = new Date(date);3
result.setMonth(result.getMonth() + months);4
return result;5
};6
7
let date = new Date('2021-08-30T08:00:00.000Z');8
9
console.log(addMonths(date, 1).toISOString()); // 2021-09-30T08:00:00.000ZOutput:
xxxxxxxxxx1
2021-09-30T08:00:00.000ZIn this example, we add a function to the Date.prototype so we can use it on any date object.
xxxxxxxxxx1
Date.prototype.addMonths = function (months) {2
let date = new Date(this.valueOf());3
date.setMonth(date.getMonth() + months);4
return date;5
};6
7
let date = new Date('2021-08-30T08:00:00.000Z');8
9
console.log(date.addMonths(2).toISOString()); // 2021-10-30T08:00:00.000ZOutput:
xxxxxxxxxx1
