How to find month of date in angular

by | Aug 30, 2024 | Technology

To find the month of a date in Angular, you can use JavaScript’s built-in Date object, or you can leverage third-party libraries like Moment.js or date-fns if you need more advanced date manipulation features.

Here’s how to do it using the native JavaScript Date object and some alternatives.

1. Using JavaScript Date Object

The Date object provides a method getMonth() that returns the month of the date as a zero-indexed number (January is 0, February is 1, etc.).

Example:

typescript

const date = new Date('2023-08-30'); // August 30, 2023
const month = date.getMonth(); // Returns 7 (0 for January, so 7 is August)
console.log(month); // Output: 7

// To get the human-readable month (1-12), add 1 to the result:
const humanReadableMonth = month + 1;
console.log(humanReadableMonth); // Output: 8 (August)

2. Using JavaScript Intl.DateTimeFormat

You can use Intl.DateTimeFormat for a localized month name if you want a more readable format.

Example:

typescript

const date = new Date('2023-08-30');
const monthName = new Intl.DateTimeFormat('en', { month: 'long' }).format(date);
console.log(monthName); // Output: "August"
  • The { month: 'long' } option returns the full month name.
  • { month: 'short' } will give you the abbreviated month name like “Aug”.

3. Using Moment.js (If you are using Moment.js in your project)

Moment.js simplifies date manipulation, and you can extract the month easily.

Installation:

bash

npm install moment --save

Example:

typescript

import * as moment from 'moment';

const date = moment('2023-08-30');
const month = date.month(); // Returns 7 (0-indexed)
console.log(month); // Output: 7

// To get the human-readable month (1-12):
const humanReadableMonth = month + 1;
console.log(humanReadableMonth); // Output: 8 (August)

// To get the month name:
const monthName = date.format('MMMM');
console.log(monthName); // Output: "August"

4. Using date-fns (If you prefer a smaller library)

date-fns is a lightweight alternative to Moment.js for date manipulation.

Installation:

bash

npm install date-fns --save

Example:

typescript

import { format } from 'date-fns';

const date = new Date('2023-08-30');

// To get the month number (1-12):
const month = format(date, 'M');
console.log(month); // Output: "8"

// To get the month name:
const monthName = format(date, 'MMMM');
console.log(monthName); // Output: "August"

Summary:

  • JavaScript Date Object: Use getMonth() and add 1 for a human-readable month number.
  • Intl.DateTimeFormat: Use for localized month names.
  • Moment.js or date-fns: Great for more advanced date handling and formatting.
