How to Get Month Name from a Date in JavaScript

Use the toLocaleString() Method

You can simply use the toLocaleString() method to get the month name from a date in JavaScript.

This method is supported in all major modern browsers. Let's take a look at an example:

// Creating a date object
var today = new Date();

// Getting full month name (e.g. "June")
var month = today.toLocaleString('default', { month: 'long' });
console.log(month);

Similarly, you can get the month name from a date string as shown in the following example:

// Creating a date object
var today = new Date('2021-10-06'); // yyyy-mm-dd

// Getting short month name (e.g. "Oct")
var month = today.toLocaleString('default', { month: 'short' });
console.log(month);

To specify options but use the browser's default locale, use 'default'. Possible values for month property are "numeric", "2-digit", "narrow", "short", "long".
