Getting Started with Luxon

Let's start by installing Luxon into your project. You can use a package manager like npm or yarn:

npm install luxon

Now, you can import Luxon into your JavaScript files:

import { DateTime } from 'luxon';

Creating Date and Time Objects

Luxon makes creating dates and times incredibly easy. You can use various methods to create DateTime objects:

From a Date String:

const myDateTime = DateTime.fromFormat('2023-10-26T10:30:00', 'yyyy-MM-ddTHH:mm:ss');
console.log(myDateTime);

From Individual Components:

const myDateTime = DateTime.fromObject({
  year: 2023,
  month: 10,
  day: 26,
  hour: 10,
  minute: 30,
});
console.log(myDateTime);

Getting the Current Date and Time:

const now = DateTime.now();
console.log(now);

Working with Dates and Times: Luxon DateTime Examples

Here are some real-world examples of how Luxon simplifies your work with dates and times:

1. Formatting Dates and Times:

const myDateTime = DateTime.fromFormat('2023-10-26T10:30:00', 'yyyy-MM-ddTHH:mm:ss');

console.log(myDateTime.toFormat('dd/MM/yyyy')); // Output: 26/10/2023
console.log(myDateTime.toFormat('HH:mm:ss')); // Output: 10:30:00
console.log(myDateTime.toFormat('cccc, LLLL dd, yyyy')); // Output: Thursday, October 26, 2023

2. Adding or Subtracting Time:

const myDateTime = DateTime.fromFormat('2023-10-26T10:30:00', 'yyyy-MM-ddTHH:mm:ss');

console.log(myDateTime.plus({ days: 3 })); // Adds 3 days to the date
console.log(myDateTime.minus({ hours: 2 })); // Subtracts 2 hours from the time

3. Checking for a Specific Day:

const myDateTime = DateTime.fromFormat('2023-10-26T10:30:00', 'yyyy-MM-ddTHH:mm:ss');

console.log(myDateTime.weekday === 4); // Returns true if the day is Thursday

4. Working with Durations:

const startTime = DateTime.fromFormat('2023-10-26T10:30:00', 'yyyy-MM-ddTHH:mm:ss');
const endTime = DateTime.fromFormat('2023-10-27T14:15:00', 'yyyy-MM-ddTHH:mm:ss');

const duration = endTime.diff(startTime, ['hours', 'minutes']);
console.log(duration.toObject()); // Output: { hours: 23, minutes: 45 }

5. Time Zone Handling:

const londonDateTime = DateTime.fromFormat('2023-10-26T10:30:00', 'yyyy-MM-ddTHH:mm:ss').setZone('Europe/London');
const newYorkDateTime = londonDateTime.setZone('America/New_York');

console.log(londonDateTime.toFormat('HH:mm:ss z')); // Output: 10:30:00 GMT+01:00
console.log(newYorkDateTime.toFormat('HH:mm:ss z')); // Output: 05:30:00 GMT-04:00
