An international PHP extension for DateTime.


use Carbon\Carbon;

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

$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');

// Don't really want this to happen so mock now
Carbon::setTestNow(Carbon::createFromDate(2000, 1, 1));

// comparisons are always done in UTC
if (Carbon::now()->gte($internetWillBlowUpOn)) {

// Phew! Return to normal behaviour

if (Carbon::now()->isWeekend()) {
    echo 'Party!';
// Over 200 languages (and over 500 regional variants) supported:
echo Carbon::now()->subMinutes(2)->diffForHumans(); // '2 minutes ago'
echo Carbon::now()->subMinutes(2)->locale('zh_CN')->diffForHumans(); // '2分钟前'
echo Carbon::parse('2019-07-23 14:51')->isoFormat('LLLL'); // 'Tuesday, July 23, 2019 2:51 PM'
echo Carbon::parse('2019-07-23 14:51')->locale('fr_FR')->isoFormat('LLLL'); // 'mardi 23 juillet 2019 14:51'

// ... but also does 'from now', 'after' and 'before'
// rolling up to seconds, minutes, hours, days, months, years

$daysSinceEpoch = Carbon::createFromTimestamp(0)->diffInDays(); // something such as:
                                                                // 19817.6771
$daysUntilInternetBlowUp = $internetWillBlowUpOn->diffInDays(); // Negative value since it's in the future:
                                                                // -5037.4560

// Without parameter, difference is calculated from now, but doing $a->diff($b)
// it will count time from $a to $b.
Carbon::createFromTimestamp(0)->diffInDays($internetWillBlowUpOn); // 24855.1348


With Composer

$ composer require nesbot/carbon
    "require": {
        "nesbot/carbon": "^3"
require 'vendor/autoload.php';

use Carbon\Carbon;

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

Without Composer

Why are you not using composer? Download the Carbon latest release and put the contents of the ZIP archive into a directory in your project. Then require the file autoload.php to get all classes and dependencies loaded on need.

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

use Carbon\Carbon;

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


⚠️ Documentation is being updated to reflect behavior on the version 3 See the migration section listing the main differences between Carbon 2 and Carbon 3

If you see a section referring to Carbon 2 behavior outside this section or have any doubt about other documentation part, do not hesitate to open an issue to raise it.
