A simple PHP API extension for DateTime.

printf("Right now is %s", Carbon::now()->toDateTimeString());
printf("Right now in Vancouver is %s", Carbon::now('America/Vancouver')); // automatically converted to string
$tomorrow = Carbon::now()->addDay();
$lastWeek = Carbon::now()->subWeek();

// Carbon embed 137 languages:
echo $tomorrow->locale('fr')->isoFormat('dddd, MMMM Do YYYY, h:mm');
echo $tomorrow->locale('ar')->isoFormat('dddd, MMMM Do YYYY, h:mm');

$officialDate = Carbon::now()->toRfc2822String();

$howOldAmI = Carbon::createFromDate(1975, 5, 21)->age;

$noonTodayLondonTime = Carbon::createFromTime(12, 0, 0, 'Europe/London');

$internetWillBlowUpOn = Carbon::create(2038, 01, 19, 3, 14, 7, 'GMT');

if (Carbon::now()->isWeekend()) {
    echo 'Party!';
echo Carbon::now()->subMinutes(2)->diffForHumans(); // '2 minutes ago'

Getting Started

1.x is compatible with PHP 5.3+.
2.x version requires PHP 7.1.8+.


The easiest and recommended method to install Carbon is via composer.

Use the following command to install with composer.

$ composer require nesbot/carbon

This will automatically get the latest version and configure a composer.json file.

require 'vendor/autoload.php';

use Carbon\Carbon;

printf("Now: %s", Carbon::now());

If you wish you can create the following composer.json file and run composer install to install it.

    "require": {
        "nesbot/carbon": "^1.33"

Carbon 2 is not yet officially supported by Laravel but if you want to give it a try in your Laravel project, you can follow those steps.

Set explicitly the Carbon version and add the adapter in your composer.json:

    "require": {
        "nesbot/carbon": "2.0.0-beta.4 as 1.25.0"
        "kylekatarnls/laravel-carbon-2": "^1.0.0"

Then update your dependencies by running.

$ composer update

Why are you not using composer?

Download the last release (or any other you want) here: releases.

Release package is the asset named Carbon-x.y.z.zip where x.y.z is the version number.

Extract the zip in a directory in your project, then require the autoload.php file to make any Carbon class available:

require 'path/to/Carbon/autoload.php';

use Carbon\Carbon;
use Carbon\CarbonInterval;

printf("Now: %s", Carbon::now());

printf("1 day: %s", CarbonInterval::day()->forHumans());

Those packages contain symfony/translation to make diffForHumans method vailable in different languages.

Install with composer is still a better option since it allows you to get the symfony/translation (and possible future dependencies) version that suit the best your PHP version and keep the whole think up-to-date via composer update command.
