Hi Friends 👋,

Welcome To Infinitbility! ❤️

To add weeks in the date using moment js, just use the moment().add() method by passing two parameters, first is the number of weeks you want to add, and the second parameter is 'weeks' it’s means want to add weeks.

Just import moment in your file and invoke moment().add(30, 'weeks'); it will show the current date time plus 30 weeks.

moment().add(20, 'weeks');

Today, I’m going to show How do I add weeks in moment js, here I will use the momentjs common method add() to add weeks in the date object.

Installation

Use the below installation command as per your package manager, moment support npm, Yarn, NuGet, spm, and meteor.

npm install moment --save   # npm
yarn add moment             # Yarn
Install-Package Moment.js   # NuGet
spm install moment --save   # spm
meteor add momentjs:moment  # meteor

Example in reactjs

In the following example, we are going to do

  1. import the moment package
  2. create a function and console the current time.
  3. add weeks in the current time and re-console it.

let’s write the code.

import moment from "moment";

// create a function and console moment
function consoleTheMoment() {
    let currentDateTime = moment();
    console.log("currentDateTime", currentDateTime)
    // add weeks in current time and re console it.
    currentDateTime =  moment(currentDateTime).add(30, 'weeks')
    console.log("currentDateTime plus 30s", currentDateTime)
}

function App() {
  consoleTheMoment()
  return (
    <div>
        {/* moment in react render */}
      {moment().format("hh:mm:ss")}
    </div>
  );
}

export default App;

In the above program, we call moment().add() in simple custom function and and add 30 weeks in it.

let’s check the output.
