In JavaScript, Moment.js is a commonly used library for manipulating and formatting dates. It provides a simple and intuitive API for working with dates and times.

In this blog post, we will explore how to adjust a Moment.js object to the first day of the month. This can be useful in various scenarios where you need to perform calculations or comparisons within a specific month.

Prerequisites

Before proceeding, make sure you have Moment.js installed in your project. You can easily install it by running the following command:

npm install moment

Adjusting the Moment object

To set the moment object to the first day of the month, we can make use of Moment.js’ startOf() function.

Here’s an example of how you can adjust a moment object to the first day of the month:

const moment = require('moment');

// Create a moment object representing the current date
const today = moment();

// Set the moment object to the first day of the month
const firstDayOfMonth = today.startOf('month');

// Output the adjusted moment object
console.log(firstDayOfMonth.format('YYYY-MM-DD'));

In the above code snippet, we first import the Moment.js library using require. We then create a moment object representing the current date using the moment() function.

We subsequently use the startOf() function with the argument 'month' to set the moment object to the first day of the month. Finally, we format and output the adjusted moment object using the format() function.

By using the startOf() function with the 'month' parameter, Moment.js effectively adjusts the moment object to the first day of the current month, regardless of the current date.

Conclusion

Adjusting a Moment.js object to the first day of the month is a common operation when working with dates and times. Moment.js provides a simple and straightforward way to achieve this using the startOf() function.

In this blog post, we explored how to adjust a Moment.js object to the first day of the month and provided an example code snippet. By following these steps, you can easily perform calculations and comparisons within a specific month in your JavaScript projects.
