How to add 1 year to a Date in JavaScript

In this tutorial, we are going to learn about how to add 1 year to the current date in JavaScript with the help of examples.

Adding 1 year to a current Date

1. To add the 1 year to a current date, first we need to access the current date inside the JavaScript using the new Date() constructor.

const currentDate = new Date();

2. Now, we can add the 1 year to a current date using the combination of getFullYear() and

setFullYear() methods.

// it adds 1 year to a current date
currentDate.setFullYear(currentDate.getFullYear() + 1);
console.log(currentDate.toDateString());

This above code adds a 1 year to the current date, for example If today’s date is “Wed Jan 17 2024” then it adds 1 year to it and returns “Fri Jan 17 2025” .

Full example:

const currentDate = new Date();

currentDate.setFullYear(currentDate.getFullYear() + 1);
console.log(currentDate.toDateString());

Definitions

• The setFullYear() method sets the year of a Date.
• The getFullYear() method gets the current year in 4-digit format (eg: 2024).
