// comparisons are always done in UTC

    die();
}

// Phew! Return to normal behaviour
Carbon::setTestNow();

if (Carbon::now()->isWeekend()) {

}
// 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
